中文摘要：
以21份山葡萄种质资源组培苗为试材,研究了0.2%NaCl胁迫对不同山葡萄种质组培苗受害症状、盐害指数及耐盐指数的影响,并对盐害指数和耐盐指数进行了主成分分析。结果表明：盐胁迫下不同葡萄种质组培苗的受害症状、盐害指数以及耐盐指数均差异显著,主成分分析结果表明,山葡萄组培苗耐盐指数的贡献率顺序为生根率〉生根长度〉盐害指数〉株高〉侧芽萌发率,且5个生长指标均可作为评价山葡萄组培苗耐盐性的鉴定指标。
英文摘要：
Taking 21 Vitis amurensis germplasm resources as materials,inv itrosubculture plantlet were conducted,and the effect of damage symptoms,damage index and salt injury index of salt-resistance growth index under 0.2% NaCl in the rooting medium were studied.And the main element analysis of salt injury index of salt-resistance growth index of Vitis amurensis were made.The results showed that the difference of damage symptoms,damage index and salt injury index and salt-resistance growth index among different germplasm resources was significant.The results of the main element analysis showed that the index of Vitis amurensis germplasmin vitro was rooting rateroot lengthdamage index plant heightlateral bud germination rate,and these 5growth indexes could be used as identification index to evaluate the salt tolerance of Vitis amurensis germplasm resources in vitro.
