摘要
对福建、江西、浙江、安徽、湖南、广西和云南等7省区初步筛选的61株优树的假种皮皂苷产出率进行测定,对假种皮皂苷产出率在平均水平之上的31株优树进行了聚类分析,并采用灰色关联度分析方法分析了树龄、树高、胸径、冠幅面积以及优树所处区域的年平均气温、年降水量、海拔高度等因素对无患子假种皮皂苷产出率的影响。结果表明:61株优树的平均皂苷产出率为60.87%,其中福建邵武6#、安徽芜湖70#、福建顺昌2#、广西柳州108#这4株优树的平均皂苷产出率为81.17%;无患子假种皮皂苷产出率与各影响因素之间的关联度最大的是优树胸径,其次是优树所处区域的年降水量,再次分别是树高、年平均气温、树龄、海拔高度和冠幅面积。
The aril saponins yield were measured to 61 plus trees which came from 7 provinces such as Fujian , Jiangxi, Zhejiang, Anhui, Hunan, Guangxi and Yunnan .And cluster analysis were used on 31 plus trees that superior in aril above average .Mean-while, application of grey correlation analysis showed that the effect of superior yield in aril of Sapindus mukurossi from the factors such as tree's age, height, diameter, crown area and the annual mean temperature , annual precipitation, altitude in the regional of plus tree on the aril saponins production rate .The results showed that the average superior yield was 60.87% for the all 61 plus trees, but the 6th at Shaowu, the 70th at Wuhu, the 2th at Shunchang, the 108th at Liuzhou, those 4 plus trees average saponins production rates were 81.17%.The diameter was the highest correlation with the superior yield of the aril of Sapindus mukurossi. Next came annual precipitation of the regional of plus tree , and the third rank was tree's height, annual mean temperature , age, alti-tude and crown area .
