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 olive tree.

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

Простые ответы на действительно сложные практические вопросы в сельском хозяйстве и экологии. Конечно, с Петиолем :).

Если вы когда-либо пытались измерить площадь листа пшеницы, сои или груши, поделитесь своим опытом с нами! Мы предлагаем вам сказать, как “легко” было сделать поверхность листьев плоской и не вьющейся. Исходя из нашего опыта, это практически невозможно, особенно для пшеницы и риса, на ранней стадии вегетации!

Есть много лайфхаков, как приклеить эти листья или другим методом прикрепить их. Однако после таких манипуляций эти листья уже нельзя использовать для каких-либо других дополнительных измерений или исследований.

Поэтому, мы нашли элегантное решение этой проблемы. Наше решение применяется практически для любого вида листьев (зерновых, фруктов или овощей). Оно делает их поверхность полностью плоской и готовой к измерению. Хочешь попробовать :)?

It was interesting and challenging way but we have gone it. Finally, we have completely new Petiole.LeafArea, an Android based mobile application for biology, plant physiology, agriculture chemistry and ecology. We re-write it from scratch. Now Petiole measures not only the specific leaf area of an individual plant leaf but can measure total leaf area. Petiole will help to measure specific leaf area and total plant leaf area in taps, without any ImageJ or leaf area scanners.

Also, this version includes behind the scenes improvements to Petiole app stability and stamps of our pesky bugs.

By the way, our Petiole.LeafArea is absolutely FREE now. Don’t forget to take advantage of this.
