Title: Study on measure method of Fuji apple spur Huimin leaves' area.
Abstract: In this article,Fuji apple spur Huimin mature apple leaves were chosen as material,the relations of length of leaf,width of leaf,length of leaf multiplies width of leaf,length of leaf and width of leaf,length of leaf and length of leaf multiplies width of leaf,width of leaf and length of leaf multiplies width of leaf and area of leaf were studied.The result showed that they all take on the relations of positive correlation.Correlation quotieties between length of leaf,width of leaf,length of leaf multiplies width of leaf and area of leaf were 0.9625,0.9579,0.9825,respectively;Correlation quotieties between length of leaf and width of leaf,length of leaf and length of leaf multiplies width of leaf,width of leaf and length of leaf multiplies width of leaf and area of leaf were 0.9818,0.9827,0.9827,respectively,and all reached their significant level at 0.01.Based on them,regression equations between lenghth of leaf(x1),width of leaf(x2),length of leaf multiplies width of leaf,length of leaf and width of leaf,length of leaf and length of leaf multiplies width of leaf,width of leaf and length of leaf multiplies width of leaf and area of leaf(y)y=2.4602 x1+6.8076,y=3.9318x2+7.6062,y=0.2646x1x2+16.31,y=6.328872+1.351x1+1.951x2,y=15.6358+0.167x1+0.247x1x2,y=17.14327-0.358x2+0.288x1x2 are established.All the six regression equations could be used to measure the area of Fuji apple spur Huimin apple leaves,of which measure results of dual regression equations between length of leaf,length of leaf multiplies width of leaf and area of leaf were more accurate.In the specific application,they could be chosen according to the precision required.
