Solution


Q.

Which of the following is not an inhibitory substance governing seed dormancy           [2020]
1 Gibberellic acid  
2 Abscisic acid  
3 Phenolic acid  
4 Para-ascorbic acid  

Ans.

(1)

Gibberellic acid is involved in growth promoting activities, such as cell division, cell enlargement, pattern formation, tropic growth, flowering, fruiting, and seed formation, and is called a plant growth promoter. It breaks seed dormancy, which is antagonistic to abscisic acid.
