5. Rapid multiplication of plants
To produce disease resistant plant
To produce virus resistant plants
To produce genetically modified plants
To isolate photochemical
To preserve RET plants
To produce high yield
To produce high vigour & vitality
This process is applicable in any season.
6. To produce haploids
Applicable for plants which are sterile
Anther culture
Embryo culture
Organ culture
Shoot culture
Somatic embryogenesis
Somaclonal variations
Germplasm conservation
Phytoremedation
7. Ability of the plant cell to divide and redivide to form a
new plant.
8. The ex-plant is any plant cell, tissue or organ which we
select for tissue culture.
10. Sterilization room
Glassware washing room
Media preparation room
Inoculation room
Incubation room

Green house
17. Propagation of plant by tissue culture under aseptic
conditions.
OR
Rapid vegetative propagation of plants under in-vitro
condition.
Selection of ex plant
Multiplication
Rooting & acclimatizing
Hardening
18. In Direct Method of Propagation explants directly
developed in to meristomers without formation of callus.
19. In Indirect method of
propagation ex-plant first
develop in to callus & callus
after sub culturing gives rise
to new plantlet.
21. Ex-plant
Wash with D/W
90% ethanol
1% Hgcl2
Tween 20/80
Cut in to small pieces (1cm)
Inoculate on ms media
Callus formation
Sub culturing
Inoculation on same media
Plantlet
Hardening
22. Production of millions of copies of plants.
Large production in small space.
Disease free plant
High vigour & vitality
To isolate photochemical
Yield increases
Carried out throughout the year
