Legume seeds exhibit dormancy because of ......................
Hard seed coat
Absence of cytokinins
Absence of gibberellic acid
Correct answer: (b)
Solution: A dormant seed is one that is unable to germinate in a specified period of time under a combination of environmental factors that are normally suitable for the germination of the non - dormant seed. Dormancy is a mechanism to prevent germination during unsuitable ecological conditions, when the probability of seedling survival is low. Legume seeds exhibit dormancy because of the presence of a hard seed coat which is tough to break.
