| 内容記述 | Image analysis is a promising method for in situ leaf area measurement. However, asleaves are three-dimensional, the use of two-dimensional images captured using a digital cameracan result in underestimation. To overcome this problem, we tested a clear folder method. Beforephotographing leaves with a digital camera, we flattened the leaves by sandwiching them betweena pair of transparent plastic clear file folder sheets, which are stationery implements for carryingdocuments. Although similar methods have been previously proposed, their applicability to specieswith different leaf shapes has never been investigated. We tested the efficacy of this method using12 species from various taxa （monocots, magnoliids, and basal and core eudicots） and leaf morphology（entire vs. lobed, simple vs. compound leaves, small and large leaves）. Individual leaf areas andthe Montgomery parameters obtained using this method were then compared with those obtainedusing the standard method, which employs a flatbed digital scanner. We observed strong correlations（R2 > 0.98） between the camera and scanner data. The regression slopes were close to unity （0.96–1.01）and the intercepts were close to zero. These findings suggest that the clear folder method can be usedas an inexpensive alternative method to estimate the area of leaves in situ with acceptable accuracy.An introductory manual for readers unfamiliar with image analysis using ImageJ is presented in theend of the paper. | |||||||
