Evaluation of Gravimetric method and Digital image analysis method for estimating leaf area of tomato plants (Solanum lycopersicum Mill.)

Veselina Vasileva

Abstract: Leaf area is an important plant morphological trait. It is essential to understand the plant-soil-water relations, crop growth, potential yield, plant competition, respiration, light reflectance etc.
The methods described in this paper was used to estimate leaf area of pot experiment tomato plant in two development stage (Flowering and Fruit Formation Stage). Digital image analysis software Image J is an alternative for standard Gravimetric method for tomato leaf area measurement. The estimates by using Image J had significant linear relationships with the estimates obtained by using Gravimetric method (R2=0.9986). The Digital image analysis with software Image J can estimate leaf area of tomato plants highly accurate (98%).
