AbstractIn order to explore the effects of different altitudes on growth,development and quality of oriental tobacco in Baoshan,Yunnan,the differences of agronomic traits,dry matter mass,physical properties, chemical compositions and economic traits of oriental tobacco Samson at diferent altitudes of 7Oo,1 100 and 1500m were studied.The results showed that with the increase of altitude,the agronomic traits,physical characteristics,chemical compositions,chlorophyll content,leaf area index and economic traits showed the trend of increasing first and then decreasing. Grey correlation analysis showed that altitude had the greatest impact on dry matter mass, followed by economic traits. Compared with 700m and 1500m , the total dry weight at 1 100m significantly increased by 57.16% and 13.46% respectively,and the yield and output value significanty increased by 28.13% , 38.52% and 15.89% , 16.79% respectively. The result of principal component analysis showed that the contribution rates of the two principal components were 86.10% and 6.10% ,respectively,and the cumulative contribution rate was 92.20% . The total score of the three altitudes showed the highest at 1 100m , followed by that at 1500m ,and that at 700m was the lowest. In conclusion,under the conditions of this study,the Samson variety had better growth and development at the altitude of 1100m with relatively coordinated chemical compositions,beter qualityand economic traits,and highavailabilityof tobacco leaves,so it was suitable for planting at the altitude of 1100m :
