| 摘 要： | 通过霜冻发生后果园实地调查观测和花器官霜冻危害模拟试验，研究了天山北麓逆温带地区花期低温强度对仁用杏花器官危害程度的关系，结果表明，仁用杏不同花器官在同一低温条件下，受冻轻重程度依次为花蕾，雄蕊，子房，柱头；子房和柱头的累积受害率随温度下降而增大，在同一低温强度下柱头的累积冻害率高于子房，因此霜冻不严重时部分花的柱头褐变而子房未受到伤害，尚能正常结果。 |
| 关 键 词： | 开花期 低温 仁用杏 花器官 |

| Abstract: | The relationship between low temperature occurred in blooming period in the district of northern Tianshan Mountain and injury to blossom organs of kernelled apricot was studied through orchard investigation and laboratory simulated frost injury experiment. The result showed that the rate of accumulated injury increased with the dropping of temperature. The stigmas were more sensitive to frost injury than ovaries, and the stigmas and ovaries were damaged more badly than stamens and flower buds under the same low temperature. Therefore flowers with injured stigma and undamaged ovary could be found following frosts. |
| Keywords: | blooming period low temperature kernelled apricot blossom organ |
