| Abstract: | The appearance quality of different stalk position leaves was grading.The main physical property and chemical components was analyzed.The results were chosen as main indexes for value,and the principal component and cluster analysis were used to evaluate the quality of leaves.The results showed that the samples could be classified to three groups and nine grading.Application of analysis of principal component and cluster in tobacco quality evaluation is more effective. |
