Özet

Determination of the leaf area has great importance in terms of plant development due to giving significant information about photosynthetic capacity of the plants. Leaf area measurements also reveal significant information about growth potential. Nowadays it can be done in laboratory and with portable expensive devices. The primary objective of the present study is to determine leaf areas in computer environment without a need for a special device and functional program only over the image pixel values and to put forth the availability of such method in leaf area measurements. In this study, real leaf areas of local grape varieties grown in Hizan (Bitlis) region were determined by using image processing technique of Photoshop CS6, pixel values and pixel-area relation. The accuracy of the measurement was determined as between 99.96-100.00%. It was concluded that Photoshop CS6 software was sufficient for leaf area measurements.
