基于多元统计方法的茶树品种适应性评价研究
Comprehensive Evaluation on Adaptability of Tea Cultivars Based on Multivariate Statistical Method
摘要
Abstract
To explore the application of multivariate statistical methods in the adaptability evaluation of tea cultivars,providing reference for the promotion and application of tea cultivars.This study identified the tree height,tree width,phenological period,survival rate,germination density,fresh leaf yield,and tea making quality of 15 tea cultivars in Changsha,Hunan.The adaptability of tea tree varieties was evaluated using an evaluation model based on principal component analysis and TOPSIS.The results showed that there are 11 cultivars based on principal component analysis and TOPSIS comprehensive evaluation were superior to the control(CK).The correlation analysis results showed that the comprehensive evaluation value was highly significantly positively correlated with fresh leaf yield,tea quality,and tree width,and significantly positively correlated with germination density.There were significant differences in fresh leaf yield,tree width and tea quality between cultivars with evaluation values higher than CK and those with evaluation values lower than CK.The comprehensive evaluation method based on principal component analysis and TOPSIS can be used for the adaptability evaluation of tea cultivars.11 excellent tea cultivars suitable for popularization and application in Changsha and similar areas were selected through experiments.关键词
