Development of linear model for leaf area measurement of two medicinally important plants: Helicteres isora L. and Vitex negundo L.
Journal Title: Journal of Applied Biology & Biotechnology - Year 2017, Vol 5, Issue 3
Abstract
Leaf area is an important parameter in physiological and agronomical studies. Linear models for leaf area measurement were developed for two plant species as a non destructive method. The leaves of Helicteres isora L. and Vitex negundo L were used for the linear model development using Leaf Area Meter (LAM) software. Gravimetric (dry weight and water content) parameters were considered for the development of linear model for these plants species which showed statistically significant relationship with the parameters studied. The best correlation as represented by regression coefficient (R2) was used. It was observed that with increase in leaf area, dry weight and water content also increased and showed best correlation with the leaf area. Thus, it was concluded dry weight and water content can be taken as a parameter for developing linear model for leaf area in these plants
