The process of seed germination includes the following five changes or steps. Such five changes or steps occurring during seed germination are: (1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators and (5) Development of Embryo Axis into Seedling. (i) Imbibition: The first step in the seed [...]
The below mentioned article will highlight the factors affecting seed germination. Some of the important factors are: (1) External factors such as water, oxygen and suitable temperature. (2) Internal factors such as seed dormancy due to internal conditions and its release. I. External Factors: (i) Water: A dormant seed is generally dehydrated and contains hardly 6-15% water in its living [...]
In this article, we propose to discuss the conditions necessary for germination and types of germination in plants. Germination is the awakening of the dormant embryo. In all mature Angiospermic seeds the embryo lies in a dormant state when its physiological activities come to a minimum. Even its respiration is so slow as to be detectable only by sensitive instruments. [...]
