Q. Gibberellins can promote seed germination because of their influence on :
- Rate of cell division
- Production of hydrolyzing enzymes
- Synthesis of abscisic acid
- Absorption of water through hard seed coat
Solution :
Correct option : B Gibberellins take part in breaking of natural dormancy of seed. They stimulate the synthesis of several hydrolytic enzymes including α-amylase. These enzymes catalyse the breakdown of food reserves in the endosperm and the products of digestion diffuse to embryo where they are used in growth. So, the correct answer is ‘Production of hydrolyzing enzymes’
