【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。更多还原

【Abstract】 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-lethal temperature(LT50),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>Huangtaiping>Qiulu(1114)>1112>Qiyuexian(K9)>132>Jinhong(123)>Longfeng>Longguan>Xinshuai.更多还原
