Abstract:

Taking M.pumila ‘Longfeng’， M.pumila ‘Longguan’,M.spectabilis‘Ⅰ’, M.spectabilis‘Ⅱ’,‘Fuji’ apple five different varieties 1-year-old dormant branches of apple as test materials，annual dormant branches from the changes of leakage ratio of electrolyte and the influence of the semi-lethal temperature(LT₅₀) were investigated.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 electrolyte increased like ‘S’ curve concomitant with temperature reducing.The semi-lethal temperature for apple was from -36.4℃ to -44.7℃.The sequence of the cold resistance was M.pumila ‘Longfeng’ ＞M.spectabilis‘Ⅰ’＞M.pumila ‘Longguan’＞M.spectabilis‘Ⅱ’＞‘Fuji’ Apple.
