摘要：

为探索温湿度条件与杧果两性花率的关系，以‘台农1号杧’品种为对象，应用生物统计方法探讨了温湿度因子与两性花百分率的线性相关关系。结果表明：供试品种两性花率比较高；随着花期温度增高，两性花率提高；花芽器官分化期自开花前30 d开始至花前5 d结束；花前6～30 d的日均高温、日均温、日均低温和日积温与两性花率存在着显著或极显著的直线正相关关系；花前26～30 d是温湿度影响两性花数量最敏感时期，较高的温度和适当的空气湿度有利于两性花的形成；花前16～20 d日均湿度越大两性花率越高。

Abstract: In this paper, statistical method was applied to the study of the linear correlations between the bisexual flower percentage of ‘Tainong 1’ mango and temperature and humidity variants during and before blossom. The results showed that ‘Tainong 1’mango had a relatively high percentage of bisexual flowers, and the percentage of bisexual flowers rose as the temperature increased. The morphological differentiation of flower organs began around 30 days before blossom (DBB) and ended 5 DBB. The percentage of bisexual flower had a significant and positive linear correlation with the average diurnal highest temperature, the average diurnal temperature, the average diurnal lowest temperature and the accumulated temperature during 6 to 30 DBB. During the period from 26 to 30 DBB, temperature and humidity was vital to the formation of bisexual flower, and relatively higher temperature and suitable humidity would benefit that formation. During the period of 16 to 20 DBB, the percentage of bisexual flower rose with higher average diurnal humidity.

Key words: Mango, Bisexual flower, Temperature, Relative humidity, Accumulated temperature
