Comparative Analysis of Some Classical and Contemporary Techniquesfor Determining Leaf Blade Area
The methods for determining plant leaf blade area are considered. The methods are briefly described and assessed for the positive and negative features. The accuracy of the results, availability, speed of measurement, applicability for species with different leaf blade shape and size are considered. Using Betula pendula Roth. Leaf blade area determination as an illustration, the following 5 methods were tested for accuracy and compared: the method of tracing out the leaf blade shape onto graph paper (control), determining the weight of a leaf blade paper pattern, method of correction factors, use of Matlab software and Petiole application for smartphones.
