在 30℃、不同的空气相对湿度 (6 0 % ,70 % ,80 % ,90 % ,10 0 % )条件下 ,比较华东葡萄和里扎马特的水势、气孔开度、蒸腾速率、电导率、脯氨酸、SOD、POD、MDA的变化。结果表明 :随着湿度的增加 ,华东葡萄和里扎马特的水势增加 ,电导率、蒸腾速率、MDA、POD下降 ,SOD、脯氨酸则先降后升 ,气孔开度反应复杂 ,但总的数值变幅小。里扎马特在相对湿度 70 %～ 80 % ,华东葡萄在相对湿度 80 %～ 90 %时 ,SOD、脯氨酸均为最低值 ,可以初步认为是它们的最适生长湿度
The effects of water potential, stomatal opening, transpiration rate and electrical conductivity of East China grapes and Rizmat were compared under different air relative humidity (60%, 70%, 80%, 90%, 100%) at 30 ℃. , Proline, SOD, POD, MDA changes. The results showed that with the increase of humidity, the water potential of East China and Rizmamat increased, the conductivity, transpiration rate, MDA and POD decreased, while SOD and PR decreased first and then increased, but the stomatal opening reaction was complex, but the total The value of small amplitude. Rizmat in the relative humidity of 70% to 80%, East China grapes in the relative humidity of 80% to 90%, SOD, proline are the lowest, can be initially considered their optimum growth humidity
