摘  要：
于塑料薄膜拱棚中研究了空间电场和CO2对黄瓜(CucumissativusL.)幼苗光合作用的影响。结果表明:电场和CO2能显著提高黄瓜的净光合速率(Pn),增强植株的光合能力,并且随着光合有效辐射(PAR)的增强,各处理间差距也增大。各处理间光合能力的差异主要是由非气孔限制引起的。电场和CO2处理间黄瓜表观量子效率(AQY)无显著差异。电场显著降低黄瓜CO2饱和点(CSP)和CO2补偿点(CCP),显著提高植株的羧化效率(CE)和RuBP最大再生速率,同时显著提高植株的光呼吸速率(RP)。CO2能显著降低黄瓜光补偿点(CCP)。

摘  要：
The effects of space electro static field and CO2 on cucumber(Cucumis sativus L.)seeding's photosynthesis were studied in plastic chambers.The results showed space electro static field can significantly promoted cucumber's net photosynthetic rate(Pn),strengthened the plant's photosynthesis,and each treatment's diversity elevated with the increasing of photosynthetically active radiation(PAR).The diversity of photosynthesis was mainly caused by non-stoma restriction in each treatment.There were no significant differences on cucumber's apparent quantum efficiency(AQY)which treated by electro static field and CO2.Electro static field decreased obviously CO2 saturation point(CSP)and CO2 compensation point(CCP)in cucumber,also increased obviously plant's carboxylation efficiency(CE)and max regeneration velocity of RuBP,plant's photorespiration rate(RP)has a marked rise.CO2 can decrease significantly cucumber's light compensation point(LCP).
