Senecio is a traditional Chinese medicine with a long history of application. It was born in hillside, sparse forests, forest borders, roadsides, and trenches in the grass. There are heat detoxification, insecticide, the name of the project, cooling blood, myogenic, expelling wind dehumidification effect. Experts in the light box test showed that when the temperature is higher than 25 degrees Celsius, Senecio seeds do not germinate, with the lower the temperature, the higher the germination rate, in the 20 degrees Celsius smart light incubator environment culture for 7 days, the seed germination rate was 4% When the temperature dropped to 15 degrees Celsius, the germination rate increased to 13%. Compared with the constant germination temperature, the germination rate of senecio seeds increased significantly by 4 to 20 degrees Celsius, reaching 76%. The constant temperature is not conducive to the germination of Senecio seeds, and when the temperature exceeds 25 degrees Celsius, the seed germination will be inhibited, and the change in natural light conditions at low temperature is conducive to the germination of Senecio seeds. The germination changes under different temperature conditions have obvious trends, which are 1% at 20°C and 6% at 15°C, and 54% under outdoor light conditions. The germination index is one of the indexes that reflect the vitality of the seeds, and the higher the germination index, the higher the seed vigor. Under the condition of constant temperature, the lower the temperature, the higher the germination index, and the seed germination index of Senecio canaliculata was highest under the conditions of low temperature change. S. sylvestris seeds did not have sprouting activity at a constant temperature of more than 25 degrees Celsius, but seed vigor was highest under low temperature conditions. Tests suggest that Senecio seeds should not be stored under conditions of low temperature and humidity for a long period of time, but higher temperature drying conditions should be selected. Senecio seeds do not have a dormant period, and it can be confirmed that the embryos have already completed the differentiation and development of the embryos. However, seed germination needs to change the low temperature conditions, may be closely related to a series of low-temperature-inducible gene expression, and is also a long-term adaptation of Senecio to the ecological environment of the mountains. result.
