1. Measure the 1000-grain weight, length and other physical indicators of seeds.

2. At the fixed temperature of 5 10 15 20 25 30 degrees, or at the variable temperature of 5-1510-2015-30, the most suitable germination temperature can be found, and the germination rate and germination potential can be compared by single factor analysis of variance.

3. dure that above germination process, the sensitivity of seed to light names can be learned with or without light.

4.PEG is used to measure the water potential and drought tolerance of seeds.

5. Salt tolerance: The seed germination experiment was carried out with nacl mixed with corresponding concentration solution.
