The rapid, accurate measurement of area in biological materials of varying colors, textures, and shapes is of special concern to the plant scientist. The need for the measurement of leaf area, in particular, has prompted the search for newer and faster methods in recent years. In general, leaf area is an excellent indicator of the photosynthetic capacity of a plant and the measurement of such a...

The aim of the current study was to developed a solar leave area meter measure leaves fast and accurate Guava Lemon leaves. As well as, validated this method by comparing it with mechanical planimeter model Placom standard leaf area, image processing (LI-COR, 30000A). This technique is depending on projected photovoltaic panel that change produced electric power due captured light. accuracy pre...

accurate and nondestructive methods to determine individual leaf areas of plants are useful tools in physiological and agronomic research. a determination of the individual leaf area (la) of such species in brassicaceae family as red cabbage (brassica oleracea var. cappitata l. f. rabra), cabbage (brassica oleracea var. cappitata l. f. alba) and broccoli (brassica oleracea var. italica l.) ...

The purpose of this study was to evaluate the validity and reliability of coating methods (plaster bandage, inelastic tape, and the alginate method) and an indirect method using a three dimensional (3D) whole body scanner. The surface area of geometric solids was measured five times using the three coating methods, and analyzed through 2D scanning and a planimeter. Second, to examine the accura...
