【摘要】 研究表明,促成—避雨栽培（Forc ing-cu ltivation and Rain-shelter-cu ltivation,F-C&R-S-C）条件下7个葡萄品种:①净光合速率（Pn）日均值、光饱和点（LSP）、光补偿点（LCP）在促成阶段分别为CO2（5.74±4.33）^7.87±5.85、494¹ 110和9.6⁵1.5μmol.m-2.s-1,在避雨阶段分别为（3.85±1.82）^5.62±3.23、806¹ 407和16.5³3.5μmol.m-2.s-1;各品种的CO2饱和点（CSP）、CO2补偿点（CCP）在促成阶段分别为717¹ 500和60.6⁸8.0μL.L-1,在避雨阶段分别为944¹ 601和14.1⁵9.1μL.L-1;②在促成阶段的Pn日均值、Pn日高峰值、Pn日积分值、气孔导度（Gs）、蒸腾速率（Tr）、LSP和CSP相对于避雨阶段较高,光合表观量子效率（AQY）、羧化效率（CE）、LCP、CCP和多数品种的水分利用效率（WUE）则较低;③上述指标在不同栽培阶段各品种间的差异显著,其中‘黎明无核’、‘里扎马特’和‘郑州早玉’的Pn日均值、WUE、AQY、CE、LSP和CSP均相对较高,而LCP和CCP相对较低,较适宜该种设施栽培。更多还原

【Abstract】 Photosynthetic characteristics of 7 grapevine varieties were studied in Forcing-cultivation and Rain-shelter-cultivation（F-C & R-S-C）greenhouse by using portable photosynthetic mensurate system CIRAS-1.The results showed that: ①The value of Pn,LSP,LCP of grapevine varieties were（5.74±4.337.87±5.85is the mean of 7 data point in a day）,494-1 110,9.6-51.5 μmol·m^-2·s^-1 respectively during the F-C period,and（3.85±1.825.62±3.23）,806-1 407,16.5-33.5 μmol·m^-2·s^-1 respectively during the R-S-C period;The value of CSP,CCP of grapevine varieties were 717-1 500,60.6-88.0 μL·L^-1 respectively during the F-C period,and 944-1 601,14.1-59.1 μL·L^-1 respectively during the R-S-C period;②There were higher value of diurnal mean of Pn、diurnal peak of Pn,diurnal integral of Pn,Gs,Tr,LSP,CSP and lower value of AQY,CE,LCP,CCP during the F-C period than those during the R-S-C period.WUE of most varieties are higher during the R-S-C period;③Comparison of photosynthetic parameters before-mentioned,it showed that’Dawn Seedless’,’Rizamat’ and’Zhengzhou Zaoyu’ varieties had higher value of diurnal mean of Pn,WUE,AQY,CE,LSP,CSP and lower value of LCP,CCP than those of other varieties,thereby more adapted to Forcing-cultivation and Rain-shelter-cultivation greenhouse cultivation.更多还原
