what are the conditions necessary for germination of seeds?
48675
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.

Germinating seeds are used because they use up the oxygen in the flask to respire and release carbon dioxide as a result, which is absorbed by KOH, causing the weight of KOH to increase. Potassium hydroxide is used in this experiment played the role of absorbtion of carbon-dioxide from the plant surrounding.

Seed germination: 1-7 days. Vegetative stage, when the plant is growing just stems and leaves: three weeks to eight weeks or more. Flowering stage, when buds start to appear: five weeks to sixteen weeks or longer. Harvesting, drying, and curing: two to four weeks.

Scarification, hot water, dry heat, fire, acid and other chemicals, mulch, and light are the methods used for breaking seed coat dormancy [3]. Physiological conditions causing internal dormancy arise from the presence of germination inhibitors inside the seed.

Growing Lychee from Seed Lychee seed propagation works best with mature fruit. ... pot with moist, rich growing medium and sow a single seed at a depth of 1 inch (2.5 cm.). Keep the pot moist and warm (between 75 and 90 F., or 24 and 32 C.). Lychee seed germination usually takes between one and four weeks.

Seed dormancy is defined as a state in which seeds are prevented from germinating even under environmental conditions normally favorable for germination. These conditions are a complex combination of water, light, temperature, gasses, mechanical restrictions, seed coats, and hormone structures.

Generally speaking, it takes between 7 and 30 days for grass seed germination to begin. However, it's important to know that host of factors can influence how fast your grass grows — including weather, grass type, and soil.

Most seeds germinate when the soil temperature is between 68(and 86(F. Once germination occurs, the optimum growing temperature for theseedling is about 10(F cooler than the optimum germination temperature. Moisture is critical for germinating seeds.

This method promotes strong germination of bean seeds by maintaining steady soil moisture and temperature. ... It's much better to plant dry bean seeds into a well-moistened furrow or bed. Seed soaking does improve the germination of peas and members of the cucumber family that are planted in warm soil.
