摘要
2007～2010年对香水椰子果实大小与裂果率进行观测后,对其裂果率与气候因子的相关和通径分析,结果表明:香水椰子的裂果率与各气候因子之间有一定的相关性,其中,月均温与裂果率之间呈极显著负相关(p<0.01),月均温对裂果率的直接影响最大,月降雨天数次之;月极端最低温与裂果率之间呈显著负相关(p<0.05),其对裂果率的间接影响最大。结果还表明,同一气候因子对不同果围椰果的裂果率的直接影响也不同。
The correlation and path analysis between the fruit cracking rates of aromatic coconut and climatic factors based on fruit size and fruit cracking rates in 2007～2010 showed that there existed correlation between the fruit cracking of aromatic coconut and climatic factors,monthly temperature.Monthly temperature showed the most significant negative correlation（p 〈0.01）on the cracking rate while the raining days affected less.Monthly extremely low temperature showed significant negative correlation（p 〈0.05）on the cracking rate.Meanwhile,the direct impact to fruit cracking rate on different fruit sizes by the same climatic factors was different.
