What is meant by germination of seeds? What are the necessary conditions for germination of seeds?
Answers
Seed germination depends on both internal and external conditions. The most important external factors include right temperature, water, oxygen or air and sometimes light or darkness. Various plants require different variables for successful seed germination.
In summary, seed germination is the process of a fertilized plant ovary, or seed, developing into a mature plant. Seed germination starts with imbibition, when the seed takes in water from the soil. This triggers root growth to allow the seed to get more water.
Answer:
• Germination is the process by which an organism grows from a seed or similar structure. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant.
• The closer the temperature is to optimum the quicker germination will occur. Most seeds germinate when the soil temperature is between 68(and 86(F. Once germination occurs, the optimum growing temperature for the seedling is about 10(F cooler than the optimum germination temperature.
Importance
• Seed germination is a crucial process that influences crop yield and quality. Therefore, understanding the molecular aspects of seed dormancy and germination is of a great significance for the improvement of crop yield and quality.
