摘要:

研究表明, 促成—避雨栽培( Forcing-cultivation and Rain-shelter-cultivation, 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) 、494~1 110和9.6~5.15 μmol·m-2 ·s-1 , 在避雨阶段分别为(3.85±1.82) ~ (5.62 ±3.23) 、806~1 407和16.5~33.5 μmol·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717~1 500和60.6~88.0 μL·L - 1 , 在避雨阶段分别为944~1 601和
14.1~59.1 μL·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。

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 CIR-
AS-1. The results showed that: ①The value of Pn, LSP, LCP of grapevine varietieswere (5.74 ±4.33) -(7.87 ±5.85) ( is 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 ±1.82) - ( 5.62 ±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 - 59.1μL ·L -1 respectively during the R-S-C period; ②There were higher value of diurnalmean 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 ofmost 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 adap ted to Forcing-cultivation and Rain-shelter-cultivation greenhouse cultivation.
