This experiment was conducted to determine the influences of growth stage, stalk position and growth environment on duvatrienediols(DVT-diols) and cis-abienol production in Nicotiana tabacum L. The leaves of plants at transplanting stage contained very small amount of duvatrienediols and cis-abienol. Comparing leaves on different stalk position at flowering stage, upper and middle leaves contained more DVT-diols and cis-abienol than lower leaves. Plants grown under controlled environmental room at 3$0^{\circ}C$ contained more DVT-diols and cis-abienols than room at 18$^{\circ}C$, $25^{\circ}C$ and glass room. Tobacco plant grown under field condition produced lower levels of duvatrienediols and cis-abienol contents than glass room-grown plants. The amounts of duvatrienediols and cis-abienol of tobacco leaves significantly decreased after rain under field conditions.

4, 8, 13-Duvatriene-1, 3-viols have been identified in the cuticular lipid of fresh Sohyang (aromatic cultivar) tobacco leaves. Their $\alpha, \beta$-isomers were directly separated by SE-54 glass capillary column and identified by mass spectrometry. Gas chromatographic analysis revealed that the duvatrienediols are major components in the culticular lipid of Nicotiana Tabacum.
