Useful Survey: A Compelling Tool For Plant Leaf Data

We have worked on Petiole, a leaf area meter in a smartphone, for more than 5 years. Hence, we obtained many insights about our customers. We know how we can help to do leaf area analysis. Petiole Leaf Area is a real example of capturing plant leaf data using digital technologies. Hence, what we are doing now – exploring. We collect feedback from our customers to understand what other feature of Petiole is better to work on.

By the way, do you have any ideas?

Evaluation Methods Of Estimation of Young Apple Trees Leaf Area

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 sq.cm ) and with help of a method of computer sight using application “Petiole” on Smartphone with operational system Android (31, 28 sq.cm ) 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.

Key words: leaf blade area, definition methods, computer sight, millimeter graph paper method, gravimetric method, “Petiole” application, bi-axis apple tree.
