Q. Choose the correct statement I. Cytokinin – Delay of leaf senescene II. Auxin – Apical dominance III. Ethylene – Seed germination IV. Gibberellins – Immature falling of leaves
A) I and II
B) I and IV
C) II and III
D) II and IV
Explanation
Ethylene is a gaseous hormone responsible for fruit ripening. Germination of seed is triggered by soaking of seeds in water. After imbibing water, the embryo secretes gibberellin which stimulates the synthesis of $\alpha$ amylase. Gibberellin is not responsible for falling of leaves. Apical dominance of plants occur due to auxin hormone
