摘　　要：以杧果为试材,在经历2008年春长时间低温寡照之后,对15个品种的抗冷害能力和花序再生力进行了调查分析。结果表明:供试品种均受严重冷害,顶生花芽(或花序)大部分干枯死亡,仅金煌杧的抵抗力稍强;供试品种均具有腋花序再生能力,但品种间存在较大差异,再生力强的品种有农院14号杧、台农1号杧、凯特杧、金穗杧、紫花杧、桂热杧120号、桂热杧82号,较强的有红象牙杧、吉尔杧、秋杧、桂香杧,中等的有红金煌杧、金煌杧,较差的为贵妃杧和爱文杧;再生花序数与再生花梢率呈正相关。Resistance to cold weather of 15 mango varieties and their regeneration capacities of axiUary inflorescence, under the condition of long - term low temperature and scant sunshine in spring of 2008, were studied. The results showed that all varieties were damaged severely from cold weather, and most of terminal blossom buds （or inflores- cences） were dry to die. Among them only Jin Huang showed a relative stronger resistance to cold weather. All the varieties had regeneration capacity of inflorescence, but there were obvious differences in different varieties. The varieties of No 14 of Nong Yuan, Tainong No 1, Keitt, Jin Sui, Zi Hua, No 120 of Gui Re, and No 82 of Gui Re showed the strongest regeneration capacity, Red Ivory, Zill, Neelum, and Gui Xiang showed stronger capacity, Red Jin Huang and Jin Huang showed moderate capacity, and Sldsnake and Irwin showed weak regeneration capacity. The number of regeneration infloreseences showed positive correlation with the rate of regeneration flowering branches.
