In recent years, studies have found that snow chrysanthemum is rich in volatile oils, total saponins, amino acids, flavonoids, including aromatics, alcohols, phenols, etc. related to lowering blood pressure, blood fat, regulating blood sugar, anti-tumor and anti-aging. A variety of compounds such as terpenes, flavonoids, alkenes and alkanes. Due to the health effects of snow chrysanthemum, the demand for snow chrysanthemums has been increasing year by year. However, wild chrysanthemums are mainly distributed in high altitude areas of Kunlun Mountains. The chrysanthemums currently sold on the market are artificially cultivated chrysanthemums. Therefore, the basic research on the chrysanthemum has practical significance for the large-scale cultivation of chrysanthemum. Using intelligent light incubators for environmental simulation during the research process is more conducive to the progress of the research.

0.1% TTC bath, Petri dishes (7 and 12cm), filter paper (7 and 12cm), rice dumplings, smart light incubator, electronic balance (AR2130/C), electronic calipers, electric blast drying oven (101-2ES) , sterilization pot (BL-75A), triangle bottle. 150 seeds of Cedar were randomly selected and divided into 3 groups. The appearance of seeds was observed directly. The lateral and longitudinal diameters of the seeds were measured on an operating table using an electronic vernier caliper.

Through intelligent light incubator experiments, 7 different soaking time treatments were performed on the sebastis seed, and seed soaking for 4 h was beneficial to germination. There is no report on the suitable soaking time of Selenium seeds. The suitable temperature for the germination of the chrysanthemum seeds was 20-25 °C, and the germination rate of the chrysanthemum seeds at a temperature of 15 °C/25 °C (12h/12h) was slightly higher than the temperature of 20-25 °C, but the difference was not obvious. Some germinating seeds of Compositae require light conditions. The experiments were carried out on different light treatments of the chrysanthemum seed. Gerbera seeds germinate normally under both light and dark conditions.
