基于主成分分析的木薯抗旱栽培措施的综合评价
Assessment on Drought Resistance Cultivation of Cassava Based on Principal Component Analysis
摘要
Abstract
The effect of drought resistance for 4 treatments was analyzed under moderate stress conditions in the paper.Content of dry matter,root to top ratio (R/T ratio),leaf relative water content,membrane permeability,chlorophyll,carotenoid,soluble sugar,proline and soluble protein content were measured at 7th day after drought stress and the drought-resistance effect of 4 treatments were analyzed by principal component analysis and comprehensive evaluation.The results showed that the cumulative variance contribution rate of three principle components were reflected the 87.47％ of the original information.And the comprehensive score of principal component analysis in 4 treatments were as follows:2％ of limewater soaked (0.773) ＞ application of super absorbent polymers (0.687) ＞ stem wax (0.477) ＞ CK (0.249).关键词
