| 摘 要： | 利用龙血树产脂部位获得的真菌菌株和细菌菌株共同转化龙血树白木质,形成了木质成分中原来没有的黄酮类化合物,表明龙血树体内存在着一类能被转化成黄酮类化合物的前体物质,龙血树这种独特的抗性机制,可能与血竭形成有关。

| Abstract: | Flavones formed from xylem of D.cochinchinensis by co-culture of fungus strain and bacteria strain are separated near the resin part in the stem of D.cochinchinensis,which do not occur in xylem before transformation.The result indicated that there was a kind of primary substances in the xylem that could be transformed by microorganisms into flavone substances.This peculiar resistance mechanism to microorganism of D.cochinchinensis may be related to the formation of Resina draconis. |
