一种基于Photoshop的叶片相对病斑面积快速测定方法
A Faster Method for Measuring Relative Lesion Area on Leaves Based on Software Photoshop
摘要
Abstract
[Objective] A new and faster method for measuring Relative Lesion Area (RLA) based on software Photoshop was proposed. [Method] First, a digital image of diseased leaves is obtained by cameras or scanners. Second, the pixels of the disease spots and the whole leaf are shown by the software Photoshop. Then, the relative lesion area can be calculated. [Result] This method was proposed to measure the RLA of potato late blight and other diseases. By comparing the results of ten replicated measurements, it was found that this measurement was highly repeatable with small errors. [Conclusion] Comparing with other similar methods, this method is simple, quick, precise, and would be widely applicable.关键词
