摘要
采用数码相机获取番茄叶片的数字图像,利用Photoshop CS4图像处理软件计算叶片长度、宽度、叶面积、周长、圆度,并进行回归分析。结果表明:长、宽与叶面积和周长存在较高的回归关系,而圆度则相对独立。和其它方法相比,该方法具有准确、快速、成本低廉、无损动态观测等优点,适用于园艺研究中叶片信息的全面测定。
A method for measuring geometry features of tomato leaves was developed using digital camera and Photoshop software.Linear and nonlinear regression equations were established,which the dependent variables were leaf area,perimeter and roundness,meanwhile,the independent variables were leaf length and width.The results showed that there was significant correlationship between leaf area and its related factors.The roundness displayed relative independence of the other variables.Relative rapidity,accuracy,nondestructive and low price were the main advantages of the method,which was applicable and reliable in plant horticulture research.
