Question

Write a short note on seed dormancy.

Answer 1

• Seed dormancy is defined as a state in which seeds are prevented from germinating even under environmental conditions normally favourable for germination or seed dormancy is internal or innate inhibition of germination of otherwise normal or viable seed even when present under most favourable conditions required for its germination.
  
• Factors that cause seed dormancy includes genetical factors/cause (physiological, embryo dormancy, undeveloped cotyledon and immature embryo ), embryo factor and inhibitor factor.
• Dormancy is a mechanism to prevent germination during unsuitable ecological conditions when the probability of seedling survival is low.
