Embodiment 1
[0067] The germination rate of soybean material was calculated by setting different temperature, humidity and treatment days. It can be seen from Table 1 that under the condition of 40 ° C and the humidity of 95% of several soybean germination rate treatments, Guichun No. 8 (more resistant to deterioration) and Guixia No. 1 (not resistant to deterioration) need to be treated for a long time. The germination ability was reduced after the time, and mildew easily occurred when the humidity was 95% soybean treatment, which affected the test results. Under the condition of 50 ℃, the comprehensive germination ability of Guixia No. 1, which is not resistant to deterioration, is only reduced to about 60% when the humidity is deteriorated at 10% and 50% for 20 days, while the comprehensive germination ability of Guichun No. 8, which is more resistant to deterioration There was no significant difference from the control. The germination power of both materials was 0 when the humidity w...
Embodiment 2
[0072] Deterioration resistance of 108 soybean varieties was identified by segmented soybean deterioration identification method. The public control material D1 was Guixia No. 1, and the public control material D2 was Gui 1607.
[0073] The public control material 1 Guixia No. 1 and 50 intact seeds of 140 soybean varieties to be identified were selected for T5 treatment. The test seeds were all seeds harvested in the autumn of 2020, and repeated 3 times. After treatment, the seeds were sterilized in 75% alcohol for 5s, dried naturally and placed in a germination box (12cm*12cm) with 2 layers of germination paper, and then an appropriate amount of purified water was added to the germination box, and then covered Put a layer of germination paper on top, wet it with pure water, cover the germination box and place it in a 25°C environment for germination. After 5 days of germination, count the number of normal buds, the number of slightly damaged buds, the number of damaged buds a...
