Vedclass · Answer

(B) Seed dormancy is a state in which seeds are prevented from germinating even under environmental conditions normally favourable for germination.Factors responsible for seed dormancy include:$1$. Hard and tough seed coat $(I)$ which prevents water and oxygen uptake.$2$. Presence of growth inhibitors like Abscisic Acid $(ABA)$ $(II)$,Phenolic acids,and Para-ascorbic acid $(IV)$.$3$. Immature embryo $(V)$ which requires time to develop before germination can occur.Gibberellic Acid and Nitrates $(III)$ are actually growth promoters that help in breaking seed dormancy,not causing it.Therefore,the factors responsible for seed dormancy are $I, II, IV,$ and $V$.

Which of the following factors are responsible for seed dormancy?
$I -$ Hard and tough seed coat
$II -$ Presence of Abscisic Acid $(ABA)$
$III -$ Chemicals like Gibberellic Acid and Nitrates
$IV -$ Phenolic acids and Para-ascorbic acid
$V -$ Immature embryo
