不同海拔咖啡果实性状比较分析

摘要

为研究高海拔咖啡和低海拔咖啡质量的不同,对保山市龙陵县木城乡渔塘桠口村海拔1 400 m和海拔1 200m的咖啡鲜果的果实性状进行测量,并采用SPSS 19.0软件进行独立样本t检测和相关性检测.结果表明:咖啡鲜果重量、鲜果纵横径、果皮重量、果皮厚度、种子单重、种子纵横径、种子厚度等方面在2种海拔下具有显著差异,在果皮厚度方面,海拔1 400 m＜海拔1 200m,其他指标海拔1 400 m＞海拔1 200m.此结果表明,高海拔咖啡的质量优于低海拔咖啡的质量.%In order to study the bean quality differences of coffee grown at a high and a low altitude,the fruit characters of fresh cherries of coffee grown at the altitudes of 1400m and 1200m in Mucheng Township,Longling country,Yunnan,China were measured and the data were analyzed by using the software SPSS29.0 for t test and correlation test of their independent samples.The results showed that there were significant differences between the coffee fruits at the two altitudes in weight of coffee cherry,firuit longitudinal and latitudinal diameter,skin weight,skin thickness,seed quality,seed longitudinal and latitudinal diameter and seed thickness.The coffee cherry had a lower skin thickness at 1 400 m altitude than at 1 200 rm altitude.The other fruit characters of coffee cherry were better at 1 400 m altitude than at 1 200 m altitude.This result showed that the quality of coffee at the high altitude was superior to the quality of coffee at the low altitude.
