Temperature and humidity are the main limiting factors affecting plant growth and distribution. In production practice, choosing suitable site conditions is an effective way to increase flavonoid metabolism. In this experiment, Ginkgo seedlings were used as experimental objects. A two-factor experiment of temperature and air humidity was conducted in a light incubator to study the effects of high temperature and air humidity on the physiological and biochemical characteristics of Ginkgo biloba leaves. The main results are as follows: (1) T1 (38 ℃ / 30 ℃, 80% air humidity), T2 (38 ℃ / 30 ℃, 20% air humidity) and T4 (28 ℃ / 20 ℃, 20% air humidity) reduce the soluble sugar content, T3 (38 ℃ / 30 ℃, 50% air humidity) No significant change in treatment. As far as soluble protein content is concerned, T1 and T2 treatments are beneficial to the accumulation of soluble protein, and T3 and T4 treatments reduce the soluble protein content. In terms of Pro content, T1 treatment was beneficial to increase Pro content, T2 treatment significantly reduced Pro content, and T3 and T4 treatments were not significantly different from controls. In terms of total flavonoid content, T3 treatment reduced the content of flavonoids in Ginkgo biloba, T1 and T2 treatments increased it slightly, but the effect was not large, and T4 was very conducive to the accumulation of flavonoids. (2) For T2 recovery treatment, soluble sugar content increased, soluble protein content decreased, Pro content increased, total flavonoid content decreased. It is speculated that T2 recovery treatment 3 angel T2 primary metabolism partial recovery; for T1 recovery treatment, no change in soluble sugar , Soluble protein increased, Pro content decreased, total flavonoid content remained unchanged, indicating that T1 recovery treatment 3 angel amino acid metabolism into protein synthesis. (3) The total flavonoid content of Ginkgo biloba leaves has a very significant negative correlation (P CK> TH1> TH2> T4> T2> T3, of which T1 is better. But in terms of total flavonoid metabolism, T4 The best, followed by T1 and T2.

Temperature and humidity are the main limiting factors that affect plant growth and distribution. In production practice, the choice of suitable standing conditionis is an effective way to improve flavonoid metabolism. In this experiment, the two factors of temperature and air humidity were tested in the light culture box to study the physiological and biochemical effects of high temperature and air humidity on Ginkgo biloba. The content of soluble sugars was reduced by the content of the leachable sugars of C/30 OC, 20% air humidity) and T3 (38 degrees C/30 degrees C, 50% air humidity) treatment without significant change. In terms of soluble protein content, T1 and T2 treatment is beneficial to the accumulation of soluble proteins, and T3 and T4 treatment reduces soluble protein content. In terms of Pro content, T1 treatment is conducive to the increase of Pro content, T2 treatment significantly reduces pro content, T3 and T4 treatment with no significant difference from the control. In terms of total flavonoid content, T3 treatment reduced ginkgo flavonoid content, T1 and T2 treatment made it slightly elevated, but the impact was not significant, T4 is very conducive to the accumulation of flavonoids. (2) For T2 recovery treatment, soluble sugar content increased, soluble protein content decreased, Pro content increased, total flavonoid content decreased, thus speculating that T2 recovery treatment 3 angel T2 primary metabolism part recovery; (3) There was a significant negative correlation between the total flavonoid content of Ginkgo leaves and the soluble sugar content (P CK, TH, Th, T., T., T., T., which was superior to T1. But in terms of total flavonoid metabolism, T4 is best treated, followed by T1 and T2.

In terms of the total flavone content, T3 treatment reduced the flavone content of Ginkgo biloba, T1 and T2 treatment increased it slightly, but the effect was not significant, T4 was very conducive to the accumulation of flavone. (2) For T2 recovery treatment, soluble sugar content increased, soluble protein content decreased, pro content increased, and total flavone content decreased, so it is speculated that T2 recovery treatment can partially recover T2 newborn metabolism; for T1 recovery treatment, soluble sugar did not change, soluble protein increased, pro content decreased, and total flavone content did not change, indicating that T1 recovery treatment can metabolize amino acid to egg White matter synthesis direction transformation. (3) There was a significant negative correlation between total flavone content and soluble sugar content in Ginkgo biloba leaves (P CK > Th1 > Th2 > T4 > T2 > T3), among which T1 was the best. But in terms of Total Flavone Metabolism, T4 treatment was the best, followed by T1 and T2.<br>
