以12个葡萄砧木品种的营养袋扦插苗为试材,100mmol/L NaCl胁迫21d后,对盐害指数、新梢长度、叶片数、根数、根长、根的干鲜质量、新稍干鲜质量等生长指标以及MDA,Pro,WSS,SOD活性等生理指标进行测定.结果表明:盐胁迫下,不同葡萄砧木新梢和根系干鲜质量较对照均显著降低,新梢鲜质量抗逆系数(ARC)与盐害指数呈极显著负相关(p<0.01),新梢干质量ARC、根系干质量ARC与盐害指数呈显著正相关(p<0.05),根冠比ARC与盐害指数呈显著正相关(p<0.05),叶片中Pro含量与盐害指数呈显著正相关(p<0.01);最终确定101-14耐盐性强,贝达,110R,8B,5A耐盐性中等,山河1号,5BB,3309,山河3号,5C耐盐性弱,SO4和188-08耐盐性极弱.
With 12 bags of grape seedlings cuttage seedlings as a test material, 100mmol / L NaCl stress 21d, salt damage index, shoot length, number of leaves, root number, root length, root fresh mass, a little dry Fresh weight and other physiological indexes such as MDA, Pro, WSS and SOD were measured.The results showed that under salt stress, the dry weight of shoots and roots of different grape rootstocks was significantly lower than that of the control, the fresh shoot fresh weight resistance coefficient (ARC) and salt damage index (p <0.01). There was a significant positive correlation between ARC and salt damage index (p <0.05) (P <0.05). There was a significant positive correlation between Pro content and salt damage index in leaves (p <0.01). Finally, salt tolerance of 101-14 was strong, salt tolerance of Bedar, 110R, 8B and 5A was moderate , Shanhe 1, 5BB, 3309, Shanhe 3, 5C salt tolerance is weak, SO4 and 188-08 very weak salt tolerance.
