This document discusses different methods of plant propagation, including both sexual and asexual propagation. It focuses on asexual propagation techniques like grafting, pruning, and cuttings. For grafting, it describes how scion and rootstock tissues are joined to allow nutrient flow between plants. It outlines different types of pruning practices and their purposes. For cuttings, it explains how stem or root pieces can be placed in a medium to produce new plants independent of the parent.

1. SANDRA ROSE
ROLL NO :28, S4.B.ARCH

2. PROPOGATION OF PLANTS?
 THE PROCESS OF CREATING NEW PLANTS
 The creation can be from various sources:
such as- seeds,cuttings, bulbs and other parts.
Plant propogation can also refer to the artificial or
natural dispersal of plants.

3. PROPOGATION OF PLANTS
 Propogation can be mainly of two types. They areas
follows ;
 Sexual propogation ( seed)
 Asexual propogation

5. Sexual propagation Asexual propagation
 Seeds and spores are
mainly used.
 Genetic recombination
may occur.
 Plant produced are not
identical to the parent
plant.
 Plant parts like root,
stem and leaves are
used.
 Plants produced from a
single parent.
 Plants produced are
identical copies of
parent plant.
TYPES OF PROPOGATION

6. ASEXUAL PROPOGATION
 Plants have a number of mechanisms for asexual or
vegetative reproduction. Some of thesemethods have
been taken by the horticulturists (gardeners)to
MULTIPLY OR CLONE plants rapidly
 Plants are produced from a single parent and no
exchange of genetic materialtakes place.
 People also usevarious methods, which plats do not
use, such as- tissue culture and grafting.

7. GRAFTING

9. GRAFTING
 A horticulture technique in which tissues from one
plant is inserted into those of another such that , two
sets of vascular tissues join together.
 This type of vascular joining is known as
INOSCULATION
 In most cases, two plants are selected for grafting;
 1.Plant selected for its root is known as
ROOTSTOCK.
 2.Plnat selected for, stem, flower, leaves etc known
as SCION

10. GRAFTING
 In stem grafting , a shoot of a desired plant is grafted
nto the stock of another type.
 In bud grafting, a bud is grafted onto the stem of another
stock plant ,it is encouraged to grow by prunning off the
stem of the stock plant.
 FOR A SUCCESFUL GRAFTING?
 Vascular cambium tissues of stock and scion must be
placed in contact with each other.
 Both tissues must be kept alive, until the graft has taken.

12. GRAFTING

13. ADVANTAGES OF GRAFTING
 1.PRECOSITY: The ability to induce fruitfulness
without need of completing juvenile phase.
 2.DWARFING:Combination of characterestics in the
scion
 3.EASE OF PROPOGATION: Effective in the case,
when certain scions are difficult to propogate.
 4.HYBRID BREEDING : Grafting can reduce time of
flowering and shorten the breeding program.
 5.HARDINESS:Roots of stock plants can resist
difficult conditions.

14.  6.STURDINESS:Provides strong , tall trunk.
 7.DISEASE/PEST RESISTANCE
 8.POLLEN SOURCE
 9.REPAIR: Through bridge grafting, we can connect
tissues , so that a nutrient flow can be ensured to the
damaged tissues from the roots.
 10.CHANGING CULTIVARS : Its easy to graft a new
cultivar onto the existing limbs of established to
make it a profitable cultivar.

15. PRUNING

16. PRUNING

17. PRUNING

18. PRUNING?
 It’s a horticulural practise involving the removal of
selective plant parts such as branches ,buds , leaves .
 Pruning is done : for the removal of deadwood
,shaping(directing growth), improving or
maintaining health, reducing risk of falling branches,
preparing nursery specimens etc.
 Specialized pruning practices are applied to certain
plants such as roses , fruit trees, grapevines etc.

19. TYPES OF PRUNING
 Thinning
 Topping
 Raising
 Reduction

20. CUTTING

21. CUTTING

22. CUTTING ?
 It’s a technique in which a piece of the stem or root
of the source plant is placed in a suitable medium
such as moist soil, potting mix, coir, or rock wool.
 The cutting produces new stem, roots and thus a new
plant independent of the parent plant,
 Its also known as cloning, striking etc.

23. CUTTING

24. TYPES OF CUTTINGS
 Stem cuttings
 Root cuttings
 Scion cuttings
 Eye cuttings
 Leaf cuttings

25. IMPROVING RESULTS
 1.By providing right soil : pH value 6-6.5, humus to
increase nutrient load, sand or gravel to increase
soils water permeability.
 2.By providing the right humidity :The soil below
and from the cuttings themselves is kept moist , and
should be aerated once in a while to prevent
formation of molds.
 Even plastic bottles are also used to provide right
humidity level.
