为探明葡萄在不同生长时期的光合特性与土壤水分含量之间关系。以2年生无核白鸡心葡萄为试材，研究了不同土壤水分条件（处理Ⅰ50％、处理Ⅱ65％、处理Ⅲ80％）对无核白鸡心葡萄光合特性和荧光特性的影响。结果表明，无核白鸡心葡萄在新梢生长期、坐果期和转色期均以80％田间持水量（处理Ⅲ）时的光合速率较高，而采后期以65％田间持水量（处理Ⅱ）的光合速率较高。在水分利用效率方面，新梢生长期和采收后与处理的田间持水量呈负相关，坐果期和转色期与处理的田间持水量呈正相关。各个荧光参数在不同时期的变化总体上随处理的田间持水量增加而增大，PI各时期的变化与光合指标在各时期的变化相似，有一定相关性。 PI在新梢生长期、坐果期和转色期均以处理Ⅲ表现较好；采收后以处理Ⅱ条件下各个荧光参数表现最好。综合各项指标的结果，无核白鸡心在新梢生长期适宜采用处理Ⅲ（田间持水量80％）的灌溉量；坐果期、转色期和采收后适合采用处理Ⅱ（田间持水量65％）的灌溉量。

In order to ascertain the relationship between photosynthetic characteristics and soil water content of grape in different growth periods .Centennial seedless grape was used to study the photosynthetic and fluorescence characteristics at three different water treatment levels ( The soil moisture treatmentⅠis 50%,treatmentⅡis 65%, treatmentⅢis 80%) The results showed that:The photosynthetic rate and irrigation is positively correlated at new shoot growth period ,fruit setting period and veraison .The photosynthetic rate of the treatment Ⅱof medium irrigation amount is the highest in after picked .The water use efficiency of different period is not the same ,water use efficien-cy and irrigation quantity was negatively correlated in new shoot growth period and after picked while fruit setting period and veraison is contrary .With the overall ,the fluorescence parameters changes of Centennial seedless in dif-ferent growth periods under different water conditions were positively related to irrigation amount .The comprehen-sive photosynthetic performance ( PI) and photosynthetic parameters changes are similar .PI in the first three periods ( New shoot growth period ,fruit setting period and veraison ) showed positive correlation with moisture;the treatmentⅡof photosynthetic performance is the best after picked .Comprehensive indexes of the results were as follows:the irrigation of treatment Ⅲis suitable for Centennial seedless in shoot growth period;the irrigation of treatmentⅡis suitable for centennial seedless in fruit setting period ,veraison and after picked .
