传统的纸样称重法用来测量离体叶片的面积,烦琐、耗时、精度不高。为寻求一种适合的方法,我们对离体叶片采用扫描仪获取叶片的数字图像,利用Image J软件测量叶片的长、宽、周长、面积及叶柄的长,并与传统的纸样称重测定叶面积法进行比较。结果表明,此方法具有低成本、快速、精确等特点,适用于植物形态学、植物生理生态学、林学及农业等对叶片形态特征的测量研究工作。 |

Abstract: |
The conversational paper-weighting method in measuring the leaf area departed from the arbor is trivial,time-consuming and precision-inferior. A method for morphological analyses of leaf was developed by obtaining the digital photo of the real leaf depart from the arbor with the scanner and measuring the length,weight,perimeter and area of leaf and the length of leafstalk with Image J software. The measured data from digital photos were compared with the values from paper cut method. The results showed that this method could be used for measuring large number of samples with the advantages of low price,expeditiousness and exactness in plant morphology,plant physiological ecology,forestry and agriculture research. |
