Which of the following conditions show that the embryo of the seed is entering the state of dormancy.
(i) Dry weight of seed is increasing.
(ii) Water content is reducing.
(iii) The general metabolic activity of embryo is slowing down.
(iv) Oxygen consumption of seed is increasing.
Text Solution
Verified by ExpertsB
As the seed matures, its water content is reduced and seeds become relatively dry ( 
per cent moisture by mass). The general metabolic activity of the embryo slows down. The embryo may enter a state of inactivity called dormancy, or if favourable conditions arc available (adequate moisture, oxygen and suitable temperature), they germinate.
