5. 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.

6. 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.

7. 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

11. • 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.

12. 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

13. • 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

15. 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.
