Abstract: The 2-Dimensional digital images of cut stems captured by a CCD camera were processed with image analysis software, the uniformity coefficient and characteristic width of cut stems were computed by fitting equation, and the method for morphology characterization of cut stems was developed by combining with the distributing ranges of cut stem width. The results showed that: 1) Fitting the width of 8 cut stem samples with the function representing cut strip width distribution, the determination coefficients (R²) all exceeded 0.98 with residual errors within ±0.1, it indicated that this function also applied to cut stem width. 2) By the characteristic width and the main width range of cut stem, the morphologies of cut stems were divided into 4 types: filamentous cut stem, its characteristic width y was ≤1.2 mm and the main width range (WR) was 0.6-1.2 mm; flake cut stem, y≥1.8 mm and WR>1.8 mm; filament-like cut stem, 1.2 < y <1.8 mm and WR 0.9-1.5 mm; flake-like cut stem, 1.2 < y <1.8 mm and WR 1.2-1.8 mm. 3) When the uniformity coefficient was ≥5.5, the samples had better uniformity.
