담배의 生育段階 및 環境條件에 따른 Diterpenoids 含量 變化

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 Nirotiana 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 rage, upper and middle leaves contained more DVT-diols and cis-abienol than lower leaves. Plants grown under controlled environmental room at 30℃ contained more DVT-diols and cis-abienols, than room at 18℃, 25℃ and glass rooms. Tobacco plant grown under field condition produced lower levels of duvatrienediols and cis-ablenol contents than glass room-grown plants. The arrow is of duvatrienediols and cis-abienol of tobacco leaves significantly decreased after rain under field conditions.
