中文摘要:
      测定杨凌地区大田中六年生小白玫瑰,法国蓝,白玉霓3不同葡萄品种在浆果膨大、转色以及成熟期的净光合速率,以比较其光合生理特性,为其科学种植寻找理论依据。结果表明,①在浆果膨大期,第2节位主叶的净光合速率(Pn)高于副梢叶片,而在转色和成熟期主叶又小于副梢,第10节位主叶在不同物候期一直高于副梢叶片;②不同时期上下冠层Pn:上冠层>下冠层;③不同品种间Pn:法国蓝>白玉霓>小白玫瑰。
英文摘要:
      Study on the photosynthetic characteristics of different grapevine cultivars at different period was conducted in Yangling by Li-6400 portable photo synthesis system to provide theoretical basis for their scientific planting.The results show as the following: ① The net photosynthetic rate (Pn) of the leaf in second position is higher than secondary shoot in the berry expanding stage, and is lower than secondary shoot in the turning-color period and maturity period while the leaf in tenth position is always higher than the secondary shoot in different period;② The Pn of canopy at different periods: the top is higher than the root;③ The Pn of different grapevine cultivars is in the order of: Blue French>Ugni Blanc>Muscat Blanc.
