Abstract: A leaf area estimation model was produced for 6 cherry cultivars namely, Karakiraz, Türkoglu, Tabaniyarik, Köroglu, Kargayüregi and Barama, grown in Turkey. Lamina width, length and leaf area were measured to develop the model. The developed leaf area estimation model in the present study is: LA=(6,84-2,36XL+0,14XL2-0,016XWXL2+0,84XWXL) (r2=0.9809). In addition to model producing procedure, the model was validated using the residual values between predicted and measured leaf areas from new leaf samples of different cherry orchards. r2 values for the relationships between actual and predicted leaf areas of the tried cherry cultivars were found to be 0.9757.
