摘要:【目的】本文旨在探索快速且准确测定植物叶面积的有效方法。【方法】本试验以中国北方常用的14种园林绿化植物为材料,采用5种不同方法测定其叶面积,并将叶长、叶宽等叶片参数与叶面积进行回归分析,确定系数回归法中叶面积换算的最佳叶片参数,以期为生产和科研提供参考依据和方法。【结果】叶面积仪法、方格计数法、复印纸称重法和数字图像法所获得的叶面积数据之间均存在显著的线性相关关系(P <0.01),数字图像法是叶面积测量中最稳定的一种方法。14种植物的叶面积、叶周长、叶长、叶宽、叶长/叶宽差异均较显著(P <0.01)。14种植物的平均叶面积、叶周长、叶长、叶宽、叶长/叶宽分别为1.11~20.62 cm2、4.43~22.33 cm、1.47~7.90cm、1.02~4.76 cm、1.11~2.89。【结论】叶长和叶宽的乘积与叶面积拟合的线性关系(A=0.72L·W+0.37)和幂指数关系(A=0.78(L·W)^(0.97))最好,均达到显著相关性(P <0.01),在实践中这两个方程均可作为测算14个树种叶面积的回归方程。
【Objective】This paper aimed to explore an effective method for rapid and accurate determination of plant leaf area.【Method】The experiment used 14 kinds of garden greening plants commonly used in north China as test materials.The leaf area was measured by 5 different methods,leaf parameters such as leaf length and leaf width were regression analyzed with leaf area,determined the best blade parameters for middle lobe area conversion by coefficient regression method,in order to provide reference basis and method for production and scientific research.【Result】The results showed that there was a significant linear correlation between the leaf area data obtained by leaf area meter method,grid counting method,copy paper weighing method and digital image method(P<0.01).Digital image method is the most stable method in leaf area measurement.There were significant differences in leaf area,leaf circumference,leaf length,leaf width,leaf length/leaf width among 14 species(P<0.01).The average leaf area,leaf circumference,leaf length,leaf width,leaf length/leaf width of 14 species were 1.11-20.62 cm2,4.43-22.33 cm,1.47-7.90 cm,1.02-4.76 cm,and 1.11-2.89 respectively.【Conclusion】The linear relationship(A=0.72L·W+0.37)and the power exponential relationship(A=0.78(L·W)^(0.97))between the product of leaf length and leaf width and the fitting of leaf area are the best,significant correlation was achieved(P<0.01).In practice,these two equations can be used as regression equations to calculate the leaf area of 14 tree species.
