In this paper has been showed an investigation of validity for using statistical model for estimation of single leaf area, primary and lateral leaf area. Estimation of single leaf area is based on equation gained with linear regression analyses which used sum of two lateral leaf vein lengths as independent variable. For estimation of primary and lateral shoot leaf area, a tree variable model is proposed: main leaf number and area of the major and minor leaves on base multiple regression analysis. A very high values of coeficient of determination (R**2) and satisfactory values of main absolute error (MAE) was confirmed validity of using of proposed model and good agreement between observed and estimated values of shoot leaf area.
