| 摘 要： | 叶面积大小是决定植物光合作用产物量的重要因素。为了得到一种快速、准确、灵活测定蔬菜叶面积的方法，本试
验以叶用莴苣为例，运用Image J 图像处理软件进行植株叶面积的测定，然后与传统测定方法方格计数法与纸样称重法的测
定结果进行比较验证。结果表明：方格计数法、纸样称重法与Image J 图像处理3 种方法测定结果之间不存在显著性差异；
通过方程线性回归分析发现，3 种方法之间的相关系数均在0.99 以上。由此可见Image J 图像处理软件可准确地应用于叶用
莴苣叶面积测定。

| Abstract: | Leaf area is an important factor for determining the amount of photosynthesis products in
plants．In order to obtain a rapid，accurate and flexible method for measuring vegetable leaf areas，this paper
took lettuce as an example and measured the plant leaf areas using Image J processing software，then carried out
comparative verification on the results of traditional testing method check counting method and paper weighing
method．The results showed that there was no significant difference between these 3 methods．By equation
linear regression analysis，we discovered that the correlation coefficients between these 3 methods were all
above 0.99．Therefore，the Image J processing software could be accurately applied to measure leaf area of
lettuce． |
