Abstract: To investigate the effects of morphology and structure of tobacco strips on the structure of cut tobacco, a prediction model for cut tobacco structure was established. Relationships between the morphology and structure of tobacco strips and cut tobacco structure were studied with correlation analysis, stepwise regression analysis and path analysis. The results showed that:1) The characteristic size of cut tobacco extremely significantly negatively correlated to the center distances of compactness clustering and elongatedness clustering, and extremely significantly positively correlated to the percentage of large-sized strips. The uniformity coefficient of cut tobacco extremely significantly negatively correlated to the center distances of compactness clustering and rectangular degree clustering. 2) The multivariate stepwise regression equation for the morphology and structure of tobacco strips and the characteristic indexes of cut tobacco structure reached extremely significant level (P < 0.01). 3) The most significant factors that directly and indirectly affected the characteristic indexes of cut tobacco were the characteristic indexes of tobacco strip morphology, the center distances of compactness clustering and elongatedness clustering. However, the direct and indirect effects of characteristic indexes of tobacco strip structure were relatively small, and the strip morphology significantly influenced the characteristic indexes of cut tobacco structure. Reducing the center distances of compactness clustering and elongatedness clustering could quickly promote the characteristic size of cut tobacco and narrow the distribution range of cut tobacco size.
