Name the factors reponible for gemination of seed
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.
Answer:
Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. This process influences both crop yield and quality.
A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.
Explanation:
factors responsible for germination of seeds are :
Here are some important requirements which are essential for a seed to germinate into a seedling and to a plant.
Water: It is extremely necessary for the germination of seeds. Some seeds are extremely dry and need to take a considerable amount of water, relative to the dry weight of the seed. Water plays an important role in seed germination.
Oxygen: It is an important and essential source of energy required for seed growth. It is required by the germinating seed for the metabolism and is used as a part of aerobic respiration until it manages to grow green leaves of its own. Oxygen can be found in the pores of soil particles, but if the seed is buried too deep it will be deprived of this oxygen.
Temperature: For a seed to germinate, it requires a moderate temperature of around 25-30°C. Quite obviously different seeds require different optimum temperatures.
Light or darkness: This can act as an environmental trigger. Many seeds do not germinate until sunlight falls on them.
