This document discusses methods of plant propagation in horticulture. It covers sexual propagation through seeds, artificial vegetative propagation techniques like cuttings, layering, grafting and budding. It also discusses the physiological and anatomical basis for rooting, and the role of growth regulators. Sexual propagation relies on seeds which are important for plant reproduction. Artificial techniques allow for propagating plants with desirable traits and include cuttings, layering, grafting, and tissue culture. Rooting requires auxin for initiation, and growth regulators can influence fruit crops by modifying physiological processes.

4. INTRODUCTION OF HORTICULTURE
• Propagation, the controlled perpetuation of plants, is the most basic
of horticultural practices. ... Propagation can be achieved sexually by seed or
asexually by utilizing specialized vegetative structures of the plant (tubers and
corms) or by employing such techniques as cutting, layering, grafting, and tissue
culture.

5. SEXUAL PROPAGATION- IMPORTARICE, SEED
VIABILITY AND TREATMENTS
•
•
Not all plants produce seeds, but those that do often rely on these seeds to
replicate themselves over successive seasons and years. Seeds are of immense
biological and economic importance. They contain high protein, starch and oil
reserves that help in the early stages of growth and development in a plant.
What is seed viability? The viability of the seed accession is a measure of how
many seeds are alive and could develop into plants which will reproduce
themselves, given the appropriate conditions.

6. ARTIFICIAL VEGETATIVE PROPAGATION - IMPORTANCE,
METHODS- CUTTING LAYENING GRAFTING AND BUDDING
• Grafting and Budding • Grafting and Budding are the most important means of
propagating fruit and nut trees for two reasons: 1. ... Budding and grafting allows
the use of rootstocks with desirable characteristics that make them preferable to
growing a tree on its own roots

10. • The most common types of artificial vegetative reproductive techniques include
cutting, layering, grafting, suckering, and tissue culturing. These methods are
employed by many farmers and horticulturists to produce healthier crops with
more desirable qualities.

11. PHYSIOLOGICAL AND ANATOMICAL BASIS OF
ROOTING
• Several physiological processes occur during rooting of cuttings such as: ... For
initiation of rooting in the cuttings, continuous supply of auxin is basically
required for the first 3-4 days. Usually, the cuttings do not respond to exogenous
application of auxin once the rooting process has initiated

12. • Plant propagation is the process which grows new plants from a variety of
sources: seeds, cuttings, and other plant parts. Plant propagation can also refer
to the man-made or natural dispersal of seeds

14. ROLE OF GROWTH REGULATORS IN
HORTICULTURE
• The plant growth regulators are the organic chemical compounds, other than
nutrients and vitamins, which modify or regulate physiological processes in an
appreciable measure in the plant when used in small concentration. They are
known to influence fruit set, retention, yield and quality of fruit crops.
