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?

How to measure leaf area with smartphone?

[embedyt] https://www.youtube.com/watch?v=trKJ_GPXHYw[/embedyt]

In this video, we made a brief how-to measure leaf area with a smartphone and a mobile application Petiole. It clear shows that specific leaf area measurement is not a problem and even to measure total leaf area is not an issue – less than in a minute with nothing special. Only Petiole and its Petiole kit (measuring stand and calibration pad) and three leaves of the olive tree.

There are three main stages of leaf area measurement using a smartphone.

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.

Why do we need to measure leaf surface area?

A scientist who studies plants repeatedly faced with a need to measure the leaf surface area. The most difficult task is to define complex leaves because the generally accepted scientific methods (contour method, weighting method, cutting method) have the greatest error.
