- Which one of the following statements regarding seed germination of a wild type plant is NOT correct?
(1) Low ABA and high bioactive GA can break seed dormancy.
(2) Light accompanied with high temperature can break seed dormancy.
(3) GA induces synthesis of hydrolytic enzymes in cereal grains
(4) Degradation of carbohydrates and storage proteins provide nourishment and energy to support seedling growth.
The incorrect statement is: (2) Light accompanied with high temperature can break seed dormancy.
Explanation of options:
-
(1) Low ABA and high bioactive GA can break seed dormancy — correct. Abscisic acid (ABA) maintains dormancy, while increased gibberellin (GA) promotes germination.
-
(2) Light accompanied with high temperature can break seed dormancy — not universally correct. While light and temperature cues influence dormancy in some species, many seeds require cold stratification or other factors; thus, this statement is not always true.
-
(3) GA induces synthesis of hydrolytic enzymes in cereal grains — correct; GA stimulates α-amylase production critical for starch mobilization.
-
(4) Degradation of carbohydrates and storage proteins provide nourishment and energy to support seedling growth — correct biochemical fact during germination.

November 29, 2025Kuch seed ko germinate hone k liye cold environment chahiye hota h so second option universally true nhi so incorrect option is second
ABA dormancy ko promote krta h iski low concentration and GA jo seed germination ko promote krta h alpha amylase bnata h ki High concentration dormancy ko break kr skte h
