Vyacheslav Bykov, a graduate of Agrotechnology and Ecology Department of the Tavria State Agrotechnological University (TSAU), a leading engineer at the Institute of Evolutionary Ecology of the National Academy of Science of Ukraine shares his experience of measuring leaf area and told his opinion about Petiole.

The latest experience

I would like to share my latest experience with you – at my official job we had to measure leaves of Bolle’s poplar (Pōpulus pyramidālis). We had 6 tests with 250 leaves in each. Totally, it was a big amount of work.
Our task was to measure the surface area of all leaves and we outlined them on graph paper, calculate square centimeters, but we had many errors and decided to find a new method. This was a scanning of leaves, using a special software to a color image. This application estimates the number of pixels. After that, using the third software, we calculated an area of the color fill area. So it was a very long and labor-intensive process.

A magic wand

I would ask this magic wand that an area of the leaf, which I am measuring now, will be transferred into the required cell of Microsoft Excel. Hence, I will speed up the process of leaf surface area measurement and also – to obtain results of my research. Measuring leaf area provides ambiguous value but we can extract very interesting data using it. For example, adaptive potential, an area of photosynthetic activity in a field. It is possible to define these parameters with this number. Consequently, if I had a magic wand – I would surely use it for its intended purposes.

Why Petiole?

Learn from experience, a highly interesting and fascinating application. It is the 21st century now – the age of computers, almost everyone has an Android mobile phone. I have the same phone too. After installing Petiole to my phone, I have measured 10 plant leaves just in 3 minutes. In other words, I have done this very quickly. Also, the authors of this great invention told me, that it is possible to measure leaf area exactly staying near the tree. Thanks to a special stand it is a reality now – this is great. Petiole app is very interesting and cool application. I will use it, honestly.
