Abstract Differences of plant height,leaf area,photosynthesis rate,chlorophyll content,the fresh and dry weights of root,stem and fruit,and the total dry weight of cucumber(Cucucmis sativus L.)were investigated under the optimal(25 ℃/18 ℃,day/night)and sub-low(21 ℃/15 ℃,day/night)temperature regimes.The results showed that SPAD,photosynthesis rate,leaf area,plant height,the fresh and dry weights of stem and leaf were lower under sub-low temperature than those of optimal temperature.However higher fruit number,higher...
