“贵农本地早”后代一年生木质化春梢在三种低温(-5℃、-9℃、-15℃)同时处理后,用电导法测定,其受冻伤害率小于母树及其它一些柑桔种类,表现了较强的抗寒能力。 Annuals of Guinong local early offspring of lignified spring shoots were treated with three low temperature (-5 ℃, -9 ℃, -15 ℃) simultaneously and measured by conductivity method. The damage rate of cold damage was less than those of mother tree and other citrus Type, the performance of a strong ability to cold.
