Comparison of Leaf Area Measurement Methods of Ramie
摘要
Abstract
In order to find out the best method for determining the leaf area of ramie,three kinds of leaf area measurement methods were compared and the relationships between different leaf parameters and leaf area were regressively analyzed.The results showed that these three leaf area measurement methods were all highly reliable.Three correspondent linear models were established,the correlation coefficient were all greater than 0.99,the linear models were:y1 =0.7287x1 +1.1145;y2 =1.2041x2 -16.805;y3 =1.1385x3 -11.983 respectively.The results of multi -factor variance analysis showed that different sampling locations had significant effect on width product coefficient、fresh weight coefficient and dry weight coefficient;the size of leaf had significant effect on fresh weight coefficient and dry weight coeffi-cient;the shape of leaf had significant effect on width product coefficient.When using coefficient regres-sive methods to measure leaf area,a more appropriate model accroding to different parameters of leaf should be chosen.关键词
