In tissue culture, addition of which of the following substance promotes the growth of buds?
Options
(a) colchicine
(b) urea
(c) auxins
(d) cytokinin
Correct Answer:
cytokinin
Explanation:
In tissue culture both auxin and cytokinin are essential for morphogenisis or differentiation of tissues and organs. Their comparative concentration decides the fate of morphogenesis. If cytokinin is present at higher concentration than auxin, shoot bud development occurs and if auxin is present at higher concentration than cytokinin, then root formation is promoted.
