| 摘 要： | 筛选抗寒性强的矮化砧木是我国渤海湾苹果产区发展矮化密植栽培的关键。应用电导法,测定9个矮化砧木品种枝条的相对电导率;利用SPSS软件,应用Logistic方程求得各砧木品种的低温半致死温度（LT50）。根据枝条相对电导率测定结果和各砧木品种的LT50,将所测砧木抗寒性分为3个等级：抗寒性较强的砧木为GM256、辽砧2号、77-34和GM310,抗寒性居中的砧木为SH6、SH38和Mark,抗寒性稍差的砧木为SH18和SH3。

| Abstract: | It is important to develop apple high-density cultivation by selecting dwarf rootstocks with high cold hardiness in Bohai Gulf.Electric conductivity was measured and LT50 of different dwarf rootstocks was calculated by SPSS software.The results showed that the cold hardiness of GM256,Liaozhen NO.2,77-34,and GM310 was higher,that of SH6,SH38,and Mark was in the middle,and that of SH18 and SH3 was lower. |
