摘要
Abstract
In order to explore the mechanism of salt resistance of H ip pophae rhamnoides L .,using six varieties as materials ,the indicators such as proline content ,seedling height ,dry weight and relative electric conductivity were analyzed to evaluate the salt tolerance of H ip pophae rhamnoides L .at seedling stage .The results indica-ted that there were significant difference among all indicators ,the change of seedling height ,dry weight and rel-ative electric cunductivity and the proline content could reflect the stress resistance to a certain extent .The re-sistant varieties accumulate more proline than non-resistant varieties ,the proline content ,seedling height ,dry weight and relative electric conductivity could be used as indicators of stress resistance identification of H ippo-phae rhamnoides L .breeding .关键词
