Abstract
High temperature and drought in summer are limiting factors of greenhouse tomato production in North China.Present experiment was mainly concentrated on the effects of different humidity on tomato growth,floral organ fertility and fruit setting under high temperature.Dongsheng No.1 was taken as the plant materials.The seedlings were treated with low(30%～35%),medium(55%～60%) and high(85%～90%) relative humidity(RH) under high temperature of 35 ℃ at different stages.Results showed that high temperature had significantly influence on the stage during flower differentiation to flower bud emergence.In this period the total amount of pollen were only 30% of the highest amount of pollen measured in the experiment under 30%～35% RH.The germination rate of pollen was only 16%,and the length of pollen tube was only 17.5 μm.However,with the increase of RH to 85%～90%,the amount of pollen could be increased by 60%,the germination rate of pollen could be attained 50%,and the length of pollen tube were up to 100 μm.Raising relative humidity was favorable to plant growth under high temperature.High humidity could increase plant biomass,leaf area and increase fruit setting.
