| Abstract | The analysis of the three measurement methods of leaf blade area of young bi-axis apple trees on rootstock 54-118 was made. High accuracy of the measurement results by a method of area calculation within a leaf contour on millimeter graph paper (31, 21 cm2) and with help of a method of computer sight using application “Petiole” on Smartphone with operational system Android (31, 28 cm2) was established. The gravimetric method and the use of mobile application “Petiole” appeared to be the most productive as to time consumption to carry out the operation | ||
