| 摘 要： | ０．４％一１．０％ＮａＣｌ溶液培养的雷司令葡萄新梢，引起叶片失绿、萎蔫或组织坏死，１．０％ＮａＣｌ导致叶柄萎蔫坏死。盐胁迫引起叶细胞膜透性增加，叶片净光合速率和叶圆片暗呼吸明显降低。盐害症状随ＮａＣｌ浓度的增加明显加重，并与叶龄有关。

| Abstract: | Cuttings of wine grape cultivar White Riesling(Vitis vinifera L.)were cultivated in nutrient solutionswith different concentrations of NaCl,i.e. 0,0.2%,0.4%,0.6%,0.8%,1.0%(w/v).The injury symptoms,leaf cell permeability,leaf disc dark respiration and leaf net photosynthesis were detected.NaCl(0.4%一1.0%)salinity caused leaf wilting, chlorosis,and necrosis.Leaf cell permeability was increased, leaf netphotosynthesis of cuttings and dark respiration of leaf disc were decreased under increasing NaCl(0.4%一1.0%)salinity stress. Injury symptoms of cutting leaves were enhanced by increasing salt stress.The rela-tionship among salt stress,cutting response and leaf age were discussed. |
