Callus induction
The morphology of callus is taken as a criterion for selection of callus for regeneration under stress condition.
Experiments for callus induction and regeneration were conducted in rice (Oryza sativa L). Callus was developed
from the region of the seeds and was visible within 7-10 days. The different concentration of 2, 4-D were used to
induce callus in the mature seeds. The NAA and BAP were used to the regeneration of shoot and root development
