Question
The bioassay of auxin is
avena curvature test
callus formation
culture of fungus
seed dormancy
Solution
A.
avena curvature test
Bioassay is the testing of biological activity of a substance by employing living material. Went used Avena sativa (oat) coleoptiles in a technique called Avena coleoptile curvature test.
ABA or abscisic acid induces dormancy in buds, seeds and underground storage organs. In callus culture, shoot and root regenration is generally controlled by auxin and cytokinin ratio.
