Question
Which breaks bud dormancy of potato tuber ?
Options
A.Gibberellin
B.IAA
C.ABA
D.Zeatin
Solution
Gibberellins overcome the natural dormancy of buds, seeds, tubers etc. In this way, these are antagonistic to ABA.
IAA (Indole Acetic Acid) is the principal naturally occurring auxin, found in all plants including fungi. It helps in eradication of weeds, root initiation and production of parthenocarpic fruits.
ABA (Abscisi Acid) is the natural growth inhibitor.
Zeatin is a naturally occurring cytokinin that stimulated mature plant cells to divide when added to a culture medium along with an auxin.
