Survey: a new tool to get plant leaf data

Posted by Published on January 30, 2020

We work on Petiole, a leaf area meter in a smartphone, for more than 5 years. Hence, we obtained many insights about our customers and how we can help to do leaf area analysis and plant leaf data using digital technologies. Hence, what we are doing now – we are collecting feedback from our customers to understand what other feature of Petiole is better to…

Abstract This review presents recent developments in plant photobiology and lighting systems for horticultural crops, as well as potential applications for cannabis (Cannabis sativa and C. indica) plant production. The legal and commercial production of the cannabis plant is a relatively new, rapidly growing, and highly profitable industry in Europe and North America. However, more knowledge transfer from plant studies and horticultural communities to commercial cannabis plant…

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…

Abstract Fertilizer plays an important role in increasing rice yield. More than half of all fertilizer applied to the field is not taken up, resulting in environmental damage and substantial economic losses. To address these concerns, a low-cost, coated compound fertilizer named “Xiang Nong Da” (XND), requiring only a single basal application, was studied. A two-year field experiment was conducted to test the effects of…

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)…
