Layering is a method of asexual plant propagation where roots form on a stem or branch while it is still attached to the parent plant. There are several types of layering including simple/tongue layering, compound/serpentine layering, mound/stool layering, air/goottee layering, trench/continuous layering, and tip layering. Layering has advantages such as not requiring specialized facilities or precise environmental control and producing larger plants in less time compared to other propagation methods. Factors that affect layering success include plant nutrition, stem treatment, etiolation treatment, and environmental conditions.
Layering
Layering is a method of asexual plant propagation where a stem or root is induced to form roots while still attached to the parent plant. It has the advantage of allowing the developing plant to receive water and nutrients from the parent through the connection. However, it takes more time than other propagation methods and fewer new plants can be produced from each parent plant. There are several types of layering including simple, air, compound, mound, and trench layering.

Layering propagation
Layering is a method of vegetative propagation where a stem is induced to root while still attached to the parent plant. There are several types of layering including simple layering, where a stem is bent to the ground and covered with soil, and air layering, where a stem is girdled and surrounded with moist moss to promote root formation. Layering has advantages over other propagation methods as it prevents water and carbohydrate stress on the new plant and ensures a high success rate. Factors like wounding, moisture, and growth regulators can influence the rooting of layers.
Asexual reproduction
Asexual reproduction in plants involves propagating new plants using only vegetative parts of the parent plant, allowing plants that do not produce seeds or have difficult to germinate seeds to be cultivated. Some common asexual propagation methods are cuttings, separation, division, layering, grafting, budding, and tissue culture. Tissue culture offers advantages like producing large numbers of identical plants quickly in a small space while eliminating diseases from the parent plant.

Adaptations of plants- Xerophytes and hydrophytes
Xerophytes and hydrophytes have evolved different adaptations to survive in their environments. Xerophytes, like marram grass and cacti, have adaptations such as thick waxy cuticles, sunken stomata, reduced leaves, and the ability to store water to conserve water in dry conditions. Hydrophytes, like water lilies, have adaptations like thin cuticles, many open stomata, wide flat leaves, and air spaces to thrive in aquatic environments where water is abundant. Both plant types have specialized anatomical features to maximize resource uptake and minimize water loss depending on their habitat.
Layering
Layering is a plant propagation technique where a stem or root of a plant forms roots while still attached to the parent plant. When root formation is complete, the layered portion is then removed from the parent plant. There are several types of layering including simple, trench, serpentine, stool/mound, tip, and air layering. Air layering is a technique where a portion of the stem is girdled and wrapped in moist sphagnum moss to induce root formation, without burying the stem in soil. It has the advantages of being relatively simple and usually very successful, but requires more time and effort than other layering methods.
Grafting budding
T-budding is the most common budding method for fruit and ornamental plants. It involves inserting a single bud from a budstick into a T-shaped cut made in the actively growing rootstock. An experienced propagator can perform over 2,000 T-buds in a single day. The method uses buds efficiently. Materials needed include a grafting knife, budsticks, and grafting strips. Rootstocks are selected based on traits like dwarfing and are grown indoors before budding. The process involves making cuts in the rootstock and shield bud to insert the bud, then wrapping with grafting strips. After 2-3 weeks, the graft union will form and the scion can begin growing on
Plant adaptations (bd mod)
This document discusses structural adaptations, tropisms, and hormonal control in plants. It covers how plants photosynthesize and use water and nutrients. It describes how plants adapt structurally to factors like light, temperature, water availability, and fire. It discusses tropisms like phototropism, geotropism, and thigmotropism which allow plants to grow toward beneficial stimuli. Finally, it outlines the roles of major plant hormones like auxins, gibberellins, cytokinins, abscisic acid, and ethylene in controlling growth, development, and responses to environmental conditions.

Grafting
Forsythia is a shrub with yellow blooms in early spring that grows 6-10 feet tall and 5-8 feet wide, thriving in partial shade to full sun and moist soil. Grafting involves joining two plants together so they grow as one, allowing for improved varieties by combining desirable roots and shoots. There are different types of grafting including hardwood grafting done in winter for fruit trees and ornamentals, cleft grafting, and bark grafting. Tomato grafting involves grafting greenhouse tomato varieties susceptible to disease onto rootstocks with strong disease resistance.
Cutting propagation
Stem cuttings are the most common method of vegetative plant propagation. A stem cutting is a portion of a stem that includes at least one node and is rooted to form a new plant. There are several types of stem cuttings including softwood, semi-hardwood, and hardwood cuttings. Softwood cuttings are taken from new, succulent growth while hardwood cuttings are taken from dormant, mature stems. Leaf cuttings can also be used to propagate some plants by rooting leaf blades or sections. Proper environmental conditions and sometimes treatment with rooting hormones helps promote root formation on cuttings.
Presentation
The document discusses various adaptations that plants have evolved to prevent excessive water loss in dry conditions. It provides examples of xerophytic plants and describes several key adaptations: thick waxy cuticles to reduce evaporation; sunken stomata surrounded by hairs to maintain high humidity near openings; fewer stomata and rolled or folded leaves to decrease surface area and retain moisture inside. One example analyzed in more detail is marram grass, which possesses rolled leaves, leaf hairs, and sunken stomata to tolerate dry sandy dune environments with poor water retention.
Ecolawns for the Pacific Northwest
The document discusses the concept of "ecolawns" as a more sustainable alternative to traditional grass lawns. Ecolawns aim to mimic naturally occurring lawn mixtures by including drought-tolerant grasses and broadleaf plants. Initial trials incorporated perennial ryegrass, yarrow, clovers, and daisies. These ecolawns have stayed green with minimal irrigation and no pesticide use. Further research is still needed to expand the plant palette and commercial availability of ecolawn mixtures tailored to different regions. The goal is to provide low-maintenance lawn options that require fewer inputs than traditional grass lawns.
Principle & different method of cutting & layering]
This document discusses different types of cuttings used for plant propagation, including stem cuttings, root cuttings, leaf cuttings, and leaf bud cuttings. It focuses on stem cuttings, dividing them into hardwood, semi-hardwood, softwood and herbaceous cuttings. Hardwood cuttings are taken from mature, lignified growth and include straight, mallet and heel cuttings. Semi-hardwood cuttings are taken from partially woody shoots and require treatment with auxins, cool temperatures, shade and high humidity for proper rooting. Physiological and anatomical factors that influence the rooting of cuttings are also examined.
Plant propagation techniques
This document discusses asexual plant propagation techniques used in horticulture. It describes various methods such as stem cuttings, leaf cuttings, budding, layering, separation, tissue culture, and grafting. For each method, it provides details on the process and diagrams for visual explanation. The advantages of asexual propagation and tissue culture are also summarized, such as reproducing exact clones of plants and producing new plants faster than seed propagation.
Anatomical adaptations of plants
Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place.
This explains why certain plants are found in one area, but not in another. For example, you wouldn't see a cactus living in the Arctic. Nor would you see lots of really tall trees living in grasslands.
This presentation focuses on anatomical adaptations of three major types of plants: Hydrophytes, mesophytes and xerophytes.
Kaixin's UROP_symposium_poster
The document describes an experiment testing different times for propagating hazelnut stem cuttings. Cuttings collected in September and October did not survive or root well when prepared immediately, while cuttings collected in November rooted equally well whether prepared in November, December, or January (with at least 3 weeks of cold stratification not being necessary). Cuttings started in September and October rooted significantly less than those started later, and those started in January rooted faster than those started in November. Overall, it is possible to root dormant cuttings collected in November right away with little stratification, but not cuttings collected before fall dormancy.
Xerophytes
This document discusses plant adaptations to different habitats. It focuses on xerophytes, which are plants adapted to dry habitats. The aims of the session are to measure leaf mass loss, see if xerophytes lose mass differently, learn about xerophyte adaptations, and have students ask questions about xerophytes. It then lists some common xerophyte adaptations like thick waxy cuticles, sunken stomata, leaf hairs, and extensive roots, which help prevent excessive water loss. Specific plant examples like marram grass and cacti are provided.
Plant propogation
Plant propagation can occur through seeds, cuttings, grafting, or tissue culture. Seeds contain dormant plant embryos that germinate under suitable environmental conditions like water, oxygen, temperature, and light. Cuttings involve rooting stem or branch cuttings, while grafting combines tissues from similar or dissimilar plants. Tissue culture grows plants from collected plant tissues in a sterile nutrient solution. Sexual propagation uses seeds to create genetically variable offspring, while asexual propagation through cuttings, grafting, and tissue culture replicates the exact parent plant. Propagation allows multiplying plant species, protecting endangered plants, and improving plant qualities and yields commercially.
ASEXUAL PROPAGATION.pptx
This document discusses various methods of asexual plant propagation including grafting, budding, layering, and taking cuttings. Grafting involves joining plant parts such as the stock and scion to produce a new plant. Budding uses a single detached bud. Layering roots a stem while still attached to the parent plant. Cuttings are stem, leaf, or root portions placed under conditions to form new roots. The document provides details on specific techniques for each method and their advantages such as reproducing desired varieties or combating disease.
Plants Without Seeds
There are three main types of plants without seeds: algae, mosses/liverworts/hornworts, and ferns. Algae were the earliest plants and come in green, red, and brown varieties depending on their pigments. They live in water and were the first to use photosynthesis. Mosses and related plants are small and nonvascular but can cover areas. Ferns have vascular tissue allowing them to be larger but still require water to reproduce.
5 13 establishing lawns
This document provides instructions for establishing a lawn from seed or sod. It discusses soil preparation such as tilling, fertilizing, and adjusting the pH. Different grass seed types like Kentucky bluegrass, fescue, and ryegrass are described along with their seeding rates. Proper seeding techniques like dividing the seed in half and sowing in different directions are covered. The document also addresses watering, overseeding existing lawns, sod installation, and types of grass like Bermuda grass.
Nutrient Master Class for Turf Managers and Greenskeepers
This document summarizes key ideas from a presentation on turf and lawn fertilization. It discusses choosing Iron DDP as a better source of iron that results in greener grass for longer with better uptake and less staining compared to granular iron. It also recommends using PROTINUS Seed Nutrition to give grass seeds a stronger start with earlier and more even emergence. Additionally, it stresses the importance of not overlooking other nutrients like zinc, manganese, boron, and suggests Wolf Trax DDP Nutrients which are guaranteed under their Growing Forward Guarantee.

A Modern Method for Determining Turfgrass Nutrient Requirements
This presentation was delivered at the Turfgrass Society of Korea conference on 22 January 2014. It explains how an estimate of nutrient use can be developed and compared to the minimum levels for sustainable nutrition (MLSN) guidelines. This method ensures turfgrass will be supplied with just enough nutrients to meet the plant requirements.
Plant nutrition
Plants obtain food through photosynthesis, a process where they use sunlight, water, carbon dioxide, and minerals from the soil to produce their own food. They are able to do this through structures like roots that take in water and minerals, stems that transport nutrients throughout the plant, leaves where photosynthesis occurs using chloroplasts to produce food, and pores called stomata that take in carbon dioxide. Plants also respire and take in oxygen to break down nutrients for energy, releasing carbon dioxide as a byproduct.
Turfgrass science: new developments in an exciting field, carefully illustrat...
My work with the Asian Turfgrass Center involves lots of travel, research, writing, and teaching. I usually travel to four countries each month, although this month is a treat, with only three: USA, Thailand, and Japan. As I do this work, the things that especially interest me are choosing the grass species that will be most suitable for the environment, ensuring that the grass is supplied with just enough fertilizer, but no excess, and in general to manage the turf to create a high quality surface while doing so with a minimum of water, fertilizer, pesticide, and energy inputs. I'll illustrate the importance of this through some examples from my work in Asia, and relate that to examples from Iceland, England, Spain, Oregon, and lots of other places. This won't be an especially technical presentation, although there will be a few facts and numbers shown. It will give an overview of turfgrass science as I see it from my traveling perspective.
Estimating Turfgrass Nutrient Use
Slides from a presentation on this topic at the Ontario Golf Superintendents Conference.
This presentation looks at nutrient availability, specifically at how we can ensure the grass is supplied with enough nutrients while at the same time ensuring that excess nutrients are not being applied. This involves an integrated look at plant use of nutrients, at fertilizer application, at soil nutrient levels, and leaf nutrient content. Healthy turfgrass plants are the goal, and those plants have a known concentration of nutrients in the leaves. By estimating the amount of nutrients that are harvested when the leaves are cut, and relating that to the amount of nutrients in the soil, one can make an informed judgement on whether or not an element is required as fertilizer, and if so, just how much is required.

Competition in animals and plants
This document summarizes competition between animal and plant species for resources. It discusses different types of biotic interactions including competition, predation, herbivory, parasitism, and mutualism. Competition can occur within or between species and can limit population size and influence traits through natural selection. The competitive exclusion principle and law of limiting similarity suggest that similar species cannot coexist if competing for the same exact resources. Resource partitioning allows niche differentiation that enables coexistence. Experiments on grassland plants support the R* model, which predicts that the species with the lowest resource equilibrium level will competitively exclude others. Root biomass correlates with a lower R*, giving some plants a competitive advantage.

This document discusses the importance of turfgrass roots. It explains that roots take up nutrients and water, store carbohydrates, and help control erosion. Root hairs are particularly important for absorption. Roots also have a symbiotic relationship with soil microorganisms, exchanging carbohydrates for benefits like improved nutrient uptake. Proper root growth is key to supporting a healthy, green turf above ground.
Establishing Turf
Kentucky bluegrass is a cool season grass that spreads through rhizomes and stolons. It has a poor shade tolerance but good cold tolerance and needs regular watering and fertilization. Tall fescue is also a cool season grass that tolerates some shade and has moderate drought tolerance. Proper soil preparation through tilling is important before seeding. Seeding rates vary by species, with Kentucky bluegrass requiring 1-3 pounds per 1000 square feet. Frequent light watering is needed after seeding to keep the soil surface moist until germination.
Organic Weed Control for the Home Garden - University of Hawaii
This document discusses organic weed control methods for home gardens. It defines weeds as plants growing where unwanted that compete with garden plants. While weeds cause problems, some have beneficial uses as well. The document outlines several organic weed control strategies for gardens, including cultivation, mulching, cultural practices, flaming, and organic herbicides. It provides examples of each method and tips for effective implementation.
Plant Competition in Temperate Regions
This document summarizes information about plant competition in temperate regions. It discusses how abiotic factors like precipitation determine plant growth forms in different biomes like deserts and grasslands. Competition between plant species can limit population sizes and influence community structure and diversity. The competitive exclusion principle and niche differentiation theory suggest that closely similar species cannot coexist. Tilman's R* model of competition for limiting resources was tested in Minnesota grasslands, finding support that the species with the lowest resource threshold (R*) for nitrogen wins interspecific competition. Species' R* values correlated with root biomass, indicating their different resource allocation strategies influence competitive abilities.
Environmental intractions of weeds
This document discusses the environmental interactions of weed species. It begins by defining a weed and the environment. It then discusses the interaction of weeds with their environment and how weeds interact with climate factors like light, temperature, water, and wind. It also discusses the interactions of weeds with soil properties such as salinity, texture, fertility, water, pH, and temperature. Finally, it discusses how weeds interact with biotic factors like other plant and animal species and how these interactions can affect weed persistence and distribution.

The document summarizes information about the pileated woodpecker, including its habitat, diet, breeding behaviors, predators, role in food chains and webs, and how environmental factors can affect its population. The woodpecker lives in deciduous forests with older trees, builds nests in rotting trees, and eats insects and fruits. Its eggs hatch in 12-14 days, and both parents share incubation duties and care for the young. Predators include sharp-shinned hawks and parasites like lice. The woodpecker's population is dependent on the health of the forest ecosystem and aquatic environments where it finds food.
Evaluation of allelopathic activity of parthenium on narrow leaf weeds
This document provides details about a study conducted by Zafar Mehmood to evaluate the allelopathic activity of Parthenium hysterophorus, an invasive weed, on narrow leaf weeds. It introduces Parthenium as an invasive weed with pan-tropical distribution that is damaging crops in Pakistan. The study aims to check the effects of different concentrations of Parthenium aqueous extracts and decomposed soil on the germination and growth of narrow leaf weeds. The methodology describes preparing aqueous extracts at varying concentrations and mixing dried Parthenium material in soil at different levels before decomposition and sowing test seeds. Observations on germination percentage and index will be recorded.
Root Substrate
The document discusses root systems and root substrates. It describes three basic types of root systems - fibrous, taproot, and storage taproot. Root functions include anchoring, absorbing water and minerals, and food storage. Roots systems consist of primary and secondary roots as well as root hairs, which increase surface area for absorption. The document then discusses properties of ideal root substrates, including stability, carbon-to-nitrogen ratio, bulk density, moisture retention, and pH. Several common soilless mixes are described.
