基因与环境互作对云南保山烤烟主要潜香型物质的影响

为研究云南保山烤烟不同品种潜香型物质在不同环境条件下的稳定性问题，将云南保山3个烤烟常栽品种(K326、Y87、Y99)种植在3个海拔的2种土壤上，应用AMMI模型对烤烟主要潜香型物质进行基因型(G)、环境(E)和基因型与环境(G×E)互作分析.结果表明： 基因型、环境及其互作对烤烟叶黄素含量、β-胡萝卜素含量、绿原酸含量的影响均达到显著水平；芸香苷含量主要受基因型影响.烤烟主要潜香型物质含量及其稳定性受G×E互作影响显著，叶黄素含量、β-胡萝卜素含量、绿原酸含量随海拔的增加而显著增加，其稳定性也不同程度得到加强；K326适种在中低海拔区，Y87、Y99适种在中高海拔区.

Effects of interaction of genotypes with environments on major latently fragrant substances of flue cured tobacco in Baoshan of Yunnan,Southwest China.

To study the stability of major latently fragrant substances of flue-cured tobacco of different varieties in Baoshan of Yunnan, three tobacco cultivars (K326, Y87 and Y99) in two soil types at three test sites with different altitudes were tested. The contents of major latently fragrant substances were measured and the effects of genotypes, environments and their interactions were analyzed by AMMI model. The results showed that genotypes, environments and their interactions had significant effects on the contents of lutein, β-carotene, and chlorogenic acid. The rutin content was mainly influenced by genotypes while the major latently fragrant substances and their stability were affected significantly by the interactions of genotypes and environments. The contents of lutein, β-carotene, and chlorogenic acid increased remarkably with altitude, and their stabilities were strengthened to different extents. K326 adapted well to middle-lower altitude, while Y87 and Y99 adapted well to middle higher altitude.
