摘要
为指导苹果区域化栽培,应用电导法测定了10个苹果品种在不同低温条件下一年生枝条的电导率,结合Logistic方程计算出各品种的半致死温度(LT50),从而比较出不同品种抗寒力的强弱。结果表明:10个品种的枝条半致死温度在-40~-47℃,抗寒能力从高到低为铃铛果>黄太平>秋露(1114)>1112>七月鲜(K9)>132>金红(123)>龙丰>龙冠>新帅。
In order to guide apple regional cultivation, ten apple varieties conductivity of one year old branches at different low temperatures were determined, combined with Logistic equation calculating all varieties of semi-le- thal temperature(LTs0),the cold resistance of different varieties were compared. The results showed that the branches semi-lethal temperature of 10 varieties between -40 and -47℃ ,cold resistance ability from high to low was : Lingdangguo〉 H uangtaiping) Qiulu ( 1114 ) ) 1112 〉 Qiyuexian ( K9 ) 〉 132 ) Jinhong ( 12.3 ) ) Long- feng〉 Longguan〉 Xinshuai.
