12/28/2022 0 Comments Humidity for seedlings![]() The lower the RH, the lower the content of ZT and IAA. Cytokinin (ZT) and indole acetic acid (IAA) concentrations in tomato buds were significantly lower than in CK under high temperature conditions. #Humidity for seedlings free#As relative humidity increased, soluble sugar concentrations of each organ decreased, and the free amino acid concentrations increased. The concentrations of soluble sugar and free amino acids in all organs in high temperature-treated plants were significantly higher than that in CK. ![]() At 38 ☌, the dry matter accumulation with 70% relative humidity was not significantly different from that of CK at 41 ☌, dry matter accumulation with 70% and 90% relative air humidity was significantly greater than that of 50%. The results showed that the dry matter accumulation of tomato plants under high temperature environment was significantly lower than that of CK. Two high temperature (38/18 ☌, 41/18 ☌) and three relative humidity (50 ± 5%, 70 ± 5%, 90 ± 5%) orthogonal experiments were conducted, with 28/18 ☌, 50 ± 5% (CK) as control. The objectives of this study were to determine the effect of high temperature under different RH levels on tomato growth and endogenous hormones and to determine the optimal RH for tomato seedling growth under high temperature environment. However, little information is available on the precise interaction between these factors on tomato growth. High temperature and high relative humidity (RH) are one of the most serious agricultural meteorological disasters that limit the production capacity of agricultural facilities. ![]()
