| 摘 要： | 以6种扁桃（5种国外品种,1种新疆地方品种）的1年生休眠枝条为试材,采取人工模拟外界环境的方法对6种扁桃休眠枝条进行了不同梯度的低温（-12~-36℃）处理,并测定其6种扁桃休眠枝条的电解质渗出率,配合Logistic方程对各品种扁桃休眠枝条的低温半致死温度进行了拟合。结果表明：随处理温度的不断降低,6种扁桃枝条组织的电解质渗出率变化幅度呈现明显的＂S＂形变化曲线;在-14.28~-21.52℃时,各品种扁桃枝条的半致死温度（LT50）先后出现;不同品种间表现出一定差异性,主要集中在-16~-19℃;新疆本地品种的扁桃枝条抗寒力最强。 |
| 关 键 词： | 扁桃 休眠枝条 抗寒性 电解质渗出率 半致死温度 |

| Abstract: | In this peper,annual dormant branches from six different varieties of almond(5 foreign varieties and 1 Xinjiang local variety) were used to investigate the influence of the semi-lethal temperature(LT50) on six varieties of almond.The changes of leakage ratio of electrolyte of the branches which were treated under different artificial simulated low temperature were studied.The semi-lethal temperature(LT50)was obtained on the basis of conductivity and logistic equation.The results showed that leakage ratio of... |
| Keywords: | almond dormant branches cold tolerance leakage ratio of electrolyte(REC) semi-lethal temperature(LT50) |
