[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 photoluminescence characteristics of organic multilayer quantum wells].

By the use of multi-source high-vaccum organic beam deposition system, the authors prepared organic multilayer quantum well structures, which consist of alternate organic small molecule materials PBD and Alq3. Based on 4-period organic quantum wells, different samples with different thickness barriers and wells were prepared. The authors measured the lowest unoccupied molecular orbit (LUMO) and the highest occupied molecular orbit (HOMO) by electrochemistry cyclic voltammetry and optical absorption.
