Questions on factors which effects rate of germination

Answer 1

Germination of seeds that are dormant is dependent on several factors. These are specific conditions of oxygen, water, temperature and possibly light or lack of it. Seeds are dry and must take in water to help initiate growth and allow metabolic processes to occur. Oxygen is needed for respiration, which allows the embryo plant inside the seed,  to obtain energy from the stored food inside the cotyledons(seed leaves). Temperature range affects seed germination. Too hot or too cold will inhibit germination of seeds. Each plant is adapted to its own temperature conditions for germination.

Questions on factors which effects rate of germination?

Answer:

Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence.
