Question

Legume seeds exhibit dormancy because of ......................

• A. Undeveloped embryos
• B. Hard seed coat
• C. Absence of cytokinins
• D. Absence of gibberellic acid

Answer 1

The correct option is B Hard seed coat

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.
