Vedclass · Answer

(D) Seed dormancy is a condition in which seeds are prevented from germinating even under environmental conditions normally favourable for germination. $1$. Mechanical resistance of the testa (seed coat) can prevent the embryo from expanding. $2$. Impermeability of the seed coat to water or gases like $O_2$ prevents the necessary metabolic processes required for germination. $3$. Unavailability of essential factors like water and $O_2$ directly inhibits the physiological activation of the embryo. Therefore,all these factors contribute to the delay or inhibition of seed germination.
