| 摘 要： | 对平枝栒子、小叶栒子、北美海棠、美洲南蛇藤、北海道黄杨5种冬季宿果植物于冬季进行电导率测定。结果表明:各参试树种在整个冬季的电导率呈现明显不同的变化趋势;春季与秋季电导率差值可反映出植物在冬季的受害情况;电导率波动反映出植物对低温受害的调节情况。北海道黄杨抗寒性较强,小叶栒子抗寒性差,平枝栒子、北美海棠、美洲南蛇藤抗寒性一般。

| Abstract: | The electrical conductivity was measured in 5 plants which can stay their fruits in winter-Cotoneaster horizontalis Dcne,Cotoneaster microphyllus Wall.Ex Lindl,North America crabapple,Celastrus scandens L.,Euonymus japonicus.The results showed that the electrical conductivity change rule of the tested species in the whole winter was obvious different.The damaged degree in cold environment could be known according to the different electrical conductivity between autumn and spring.The plant regulation in low ... |
