Effects of Different Climate Conditions on Tartary Buckwheat Seeds The temperature had a significant effect on the germination of tartary buckwheat seeds. In the relevant experiments, with the increase of temperature, the germination rate increased, the suitable temperature was 25°C, and the temperature was too high to reduce the germination rate. At the same time, the temperature was too high and the seedling growth was weakened. It will inevitably affect the yield and quality of seedlings. Through experiments, the best treatment levels for the effects of different temperature levels on yield and leaf Vc and flavonoid content of Tartary Buckwheat seedlings were 25°C and 30°C, respectively. The analysis showed that the environment temperature should be controlled at 25 in the early growth stage of Tartary Buckwheat seedlings. About °C, which is consistent with the actual production. The reason is that the temperature is low and the growth is slow, but the temperature is too high, the seedling grows too fast, the nutrient consumption is greater, and the growth is weaker; in the late growth stage of the bitter buckwheat seedlings, the ambient temperature should be controlled Around 30°C, in order to promote the accumulation of Vc and flavonoids in seedlings and improve the temperature of the sprouts, it has a great influence on the growth period of tartary buckwheat seedlings. At this time, we should use a small meteorological station to measure the temperature in the environment in time so that we can make timely adjustments. . The effect of different light levels on the yield, Vc and flavonoid content of tartary buckwheat seedlings is best treated at levels B1 and B2. The analysis shows that in order to improve the yield and quality of tartary buckwheat malt, the light intensity should be controlled at 1 000~3 000 lx. (B1~B2 levels), light is not too strong. The light intensity has a certain relationship with the accumulation of Vc. Gao Huaichun believes that the light is sufficient and the Vc content of pepper fruits is high. In this experiment, the strong light of B3 level (5 000 lx) Not conducive to the accumulation of Vc of Tartary Buckwheat seedlings, the importance of light is self-evident, then how do we control the illuminance, can be solved with the field microclimate automatic observer, because the field microclimate automatic observer can measure up to 11 parameters, Including light, temperature, humidity and so on. Flavonoids are the products of plant secondary metabolism, sugar and other organic matter is the material basis of plant secondary metabolism. Ouyang Sunshine believes that the accumulation of plant flavonoids is related to light. In this experiment, proper increase of temperature and light is beneficial to bitterness. Accumulation of flavonoids in buckwheat seedlings. This is due to the increase in photosynthetic products at higher temperatures and light conditions, which provides a better material basis for plant secondary metabolism. In addition, the biosynthesis of flavonoids is closely related to phenyl propane metabolism. Phenylalanine ammonia-lyase (PAL) is one of the key enzymes in phenylpropanoid metabolism. In this experiment, the effect of light on the accumulation of flavonoids in tartary stalks may also be due to light activation of the key enzymes for phenylpropanoid metabolism ( PAL) promotes phenylpropanoid metabolism and its mechanism needs further study.
