Leaf area (LA) is an important parameter in many plant modeling studies.There is a need for a simple, accurate and non-destructive model to predict LA in physiological experiments in which destructive LA sampling is not allowed (e.g., rare plants or genetically segregating populations). In this study, a model for LA estimation was developed for Plumeria rubra L. using simple linear measurements of leaf length (L)…

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…

The atmospheric [CO2] in which crops grow today is greater than at any point in their domestication history and represents an opportunity for positive effects on seed yield that can counteract the negative effects of greater heat and drought this century. In order to maximize yields under future atmospheric [CO2], we need to identify and study crop cultivars that respond most favorably to elevated [CO2]…

Trees in big cities are adopted for the surrounded conditions more than the same species of wood put down their roots in the natural conditions. In other words, we are speaking again about influence of salt-affected soil, metal heavy, gases, etc. Level of development for a tree was defined by the degree of its organs’ development, particularly leaves. We researched differences between the natural territory,…

Hello to all readers of Geektimes. Today we have a chance to chat about real development of own ideas with Andrii Seleznov, co-founder of startup Petiole. We will try to avoid winning relations and suggestions how it is easy (or difficult) and enjoyable to feel media exposure on yourself.  Instead of this, we want to write about quite a lengthy process: about how a new…
