摘要: 以茄子702幼苗为试材,研究了低温胁迫对茄子幼苗光合特性的影响。结果表明,低温胁迫下,茄子幼苗的叶绿素含量、叶绿素a/b、净光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)、光饱和点(LSP)、光饱和光合速率、表观量子效率(AQY)、CO2饱和点(CSP)、羧化效率(CE)和RuBP最大再生速率均下降;光补偿点(LCP)、CO2补偿点(CCP)均上升;胞间CO2浓度(Ci)先降低后升高。以上结果表明,低温胁迫伤害了茄子幼苗的光合机构。

关键词: 低温胁迫, 茄子幼苗, 光合特性

Abstract: Effects of low temperature stress on photosynthetic characteristics in leaves of eggplant(Solanum melongena L.)seedlings of 702 were studied.The results showed that chlorophyll contents,chlorophyll a/b,net photosynthetic rate(Pn),stomatalconductance(Gs),transpiration rate(Tr),light saturation point(LSP),photosynthetic rate at light saturation point,apparent quantum yield(AQY),CO2saturation point(CSP),carboxylation efficiency(CE)and maximum RuBP regeneration rate were decreased;Light compensation point(LCP),CO2compensation point(CCP)were increased,and intercellular CO2concentration(Ci)were decreased in the former period,and then increased.The results suggested photochemical structure of eggplant seedlings was damaged under low temperature stress.

Key words: Low temperature stress, Eggplant seedlings, Photosynthetic characteristics
