- 摘要:
- 为探明酿酒葡萄的需水规律,选择四年生酿酒葡萄赤霞珠(Cabernet Sauvignon)为试验材料,测定在充分和非充分灌溉处理条件下葡萄叶片的净光合速率(Pn)、蒸腾速率(Tr)和气孔导度(Gs)、胞间CO2浓度(Ci)和水分利用效率(WUE)共5个光合指标,研究不同灌溉处理对赤霞珠的光合作用参数日变化的影响。结果表明:充分灌溉与非充分灌溉条件下,葡萄叶片的净光合速率(Pn)、蒸腾速率(Tr)和气孔导度(Gs)日变化呈双峰曲线,出现明显“午休”现象。Pn、Tr和Gs日变化规律相近,均呈总体下降,变化趋势依次为CK>T1>T2>T3,而胞间CO2浓度呈先降低后升高趋势,水分利用效率变化趋势依次为T1>T2>CK>T3;非充分条件下,可以减少葡萄的无效蒸腾,有效提高水分利用效率,实现高效灌溉。
- Abstract:
- In order to determine the water requirement of wine grapes,we took 4 years of wine grape Cabernet Sauvignonas testing material,and investigated the daily change of five photosynthetic indexes including net photosynthetic rate(Pn),transpiration rate(Tr),stomatal conductance(Gs) intercellular CO2 concentration(Ci) and water use efficiency(WUE) under different irrigation conditions.The results showed that the daily change of Pn,Tr and Gs of grape leaf showed double-peak curve with apparent noon break phenomenon under non-full and full irrigation condition.The daily change laws of Pn,Tr and Gs were the similar to each other,with trend of general declination of CK>T1>T2>T3.While intercellular CO2 concentration showed the trend from declination to ascending,and the change trend of the water use efficiency was T1> T2>CK>T3.
