Chinese. 为探讨高温条件下CO2加富对植物热伤害的缓解效应，以“津优36号”黄瓜品种作为试验材料，研究高温、CO2加富条件下黄瓜叶绿素、可溶性糖和淀粉含量变化。结果表明，CO2施肥可以打破黄瓜在中午温度较高时的“午休”现象，促进光合作用继续进行。CO2加富同高温协同作用，能够进一步促进光合作用，叶片内可溶性糖含量和淀粉含量显著增多。CO2加富会促进黄瓜果实内可溶性糖转化为淀粉。

To investigate the regulation effect of elevated CO2 to thermal damage on plants, taking the cucumber variety JinYou No. 36 as experimental material, research the effects of elevated CO2 to chlorophyll,carbohydrate and starch. The results showed that： CO2 fertilization could break the phenomenon of ＂noon break＂ when the temperature was high at noon and boost the pimtosynthesis to continue. Elevated CO2 could act synergistically with high temperature to further boost the photosymhcsis, the content of carbohydrate and starch in the leaves were increased significantly. CO2 enrichment could promote the transformation of carbohydrate into starch in the cucumber.
