杏品种一年生休眠枝、花、幼果抗寒的相关分析

The analysis of coefficient of hardiness on shoot－tissue flowers and young fruits of varieties of apricot

用电导法并配以Logistic方程对25个杏品种的抗寒性进行鉴定，结果表明，杏1年生枝的抗寒温度在－28．5℃～－40℃，花蕾的抗寒温度在－7．0～－10．9℃，盛开花朵的抗寒温度在－3．0℃～－6．9℃，幼果的抗寒温度在－1．1℃～－2．2℃，枝、花芽和幼果彼此间抗寒性呈显著相关，其抗寒性强弱的顺序为枝＞花＞幼果，同一朵花器官的抗寒性为：花瓣＞雄蕊＞雌蕊。

The hardiness of 25 varieties or species of apricot was assayed by electrolyte leakage cooperated well with logistic equation. The result show that the hardiness of low temperature of shoot－tissue, pink buds, full flowers and young fruits was: －28.5℃~－40℃,－7.0℃~－10.9℃, －3.0℃~－6.9℃ and －1.1℃~2.2℃, respectively.There were significantly positive relationships in the hardiness among shoots pink buds,full flower and young fruit. The order of hardlness was shoots>flowers>young fruits,the order of hardiness within organ of a flower was:petal>stamen>pistil.
