Abstract:
Taking the figleaf gourd and pumpkin (Cucurbita maxima×Cucurbita moschata) as root stocks，‘Jinyou No 35’cucumber as scion，the effect of different root zone temperature conditions (optimal temperature (CK) (18-20 ℃)，suboptimal temperature (13-15 ℃)，low temperature (8-10 ℃) on the growth and photosynthesis indexes were studied.The results showed that，compared with optimal temperature (CK)，low and suboptimal temperature produced a significant inhibition on growth of cucumbers.The plant height，stem diameter，leaf area，number of leaves,shoot dry weight were all reduced,but root dry weight,root shoot ratio all increased，which the inhibition of low temperature was more significant.Low and suboptimal temperature also reduced SPAD value，net photosynthetic rate，transpiration rate，intercellular CO2 concentration，stomatal conductance of the grafted cucumber.And there were differences between different grafting，figleaf gourd at low temperature was better than the pupmkin on the performance．
