香水椰子开花授粉习性与气候因子的相关分析

Correlation Analysis between Climatic Factors and Flowering and Pollination Characteristics of Aromatic Coconut

以国外引进的香水椰子为材料,通过对开花授粉等性状指标与文昌地区主要气候因子的关系进行了相关、通径和逐步回归分析。结果表明,抽苞数、开苞数、开苞天数和授粉天数与主要气候因子显著相关,其中,影响4个性状的主要气候因子分别为月均温、月极低温、月极低温和月降雨量、月均温和月降雨天数;分别建立了4个性状与气候因子的回归方程。

With introduced aromatic coconut as materials,it was studied that the relation between flowering and pollination traits and the main climatic factors in Wenchang district by correlation analysis,path analysis and stepwise regression. Results showed that the number of inflorescences,the number of open inflorescences,days of open inflorescences and days of flower pollination were significantly related with major climatic factors. Among them,four traits were affected by the main climatic factors which were respectively monthly average temperature,monthly extremely low temperature,monthly extremely low temperature and monthly rainfall,monthly average temperature and monthly raining days. Meanwhile,regression equation of four traits and climatic factors was established.
