Abstract:: Taking the leaves of ‘Blomidon’,‘Northland’ and ‘Bluecrop’ blueberry as test materials,the relationship between leaf area(leaf length×leaf width) (y) and the growth indexes include leaf length (x₁),leaf width (x₂),leaf weight (x₃) were studied.The results showed that length,leaf width,leaf weight,leaf length×leaf width and leaf area of 3 blueberry varieties were positively correlated.A simple regression equation,and fitting equation between leaf area (y) and leaf length (x₁),leaf area (y) and leaf width (x₂),leaf area (y) and leaf weight (x₃),leaf area (y) and leaf length×leaf width were established.After data analysis,the correlation coefficient and multiple correlation coefficients were at very significant level,thus the leaf area regression equation could be used to estimate blueberry leaf area.
