Applying a digital method for measuring leaf area index of tomato plants

摘要

Non-destructive methods of measuring leaf area are suitable for scientific experiments, and allow the measurement of the same plant several times during the growing period. The method was used to estimate the Leaf Area Index (LAI) of tomato plant in different growth stages. LAI was estimated by measuring the length and width of the leaves representing the mean leaf area of the plants. The LAI estimations presented high precision and accuracy when the proposed methodology was used resulting in time and effort savings and being useful. It is cheap and may existing computer and digital camera; thus, it doesn't need extra hardware. Projected technique is going to be valuable in achieving correct area calculation.
