Application of the Adobe Photoshop Software Package in Leaf Blade Area Measurement of Woody Plants

There are a number of applied methods for determining morphometric parameters, including the area leaf blades woody plants: millimeter graph paper method, method direct measurements, punching and planimetric method. The analysis practical application in test mode revealed their shortcomings related to inaccuracy experiment duration, equipment inaccessibility. Many researchers have successfully acquired digitized images. However, capturing parameters considered structure from monitor screen is often impossible due low availability programs high cost. purpose work evaluate effectiveness existing on example birch genus (Betula L.) trees accumulate algorithm Adobe Photoshop software package. We developed plants using research subject trees. This requires: blank A4 sheets; ruler with an angle 90°; transparent adhesive tape (scotch tape); scanner. draw reference square random (but fixed) dimensions corner each sheet, step by 10 mm its borders, sheet 90°. placed strictly parallel borders. Then, desired wood species attached scotch tape. Using scanner, we convert workpiece into electronic form upload image Photoshop. In order receive you can use following program tools: “ruler”, “magic wand”, “magnetic lasso tool”. At same time, it possible automatically select borders studied object, which helps avoid subjective errors. resulting measurements displayed pixels then converted required units. obtained data verified square. Verification showed that accuracy more than 99.9 %. proposed allows perform fast accurate blades, without requiring purchase expensive equipment, makes available any researcher who faces task measuring surface plants.
