摘要: 从柬埔寨龙血树(Dracaena cochinchinensis)茎杆中分离到303株真菌,其中镰刀菌属(Fusarium)株占总分离频率的52%,其次是短梗霉(Aureobasidium)和枝孢霉(Cladosporium)。通过活体接种对血竭产生的影响试验表明,对血竭形成起重要作用的真菌主要是禾谷镰刀菌龙血树变种(F.graminum var.dracaena)等4株红色镰刀菌,可使血竭形成量提高66%-120%。

Abstract: 303 strains of fungi were isolated from the stems of Dracaena cochinchinensis collected from Xishuang banna of Yunnan. The isolated frequency of Fusarium is 52 of total isolation frequency. Secondly, the isolation frequency of Aureobasidium, Cladosporium, Penicillium, Rhizoctonia, Sporotrichum are respectively 5.9, 4.0, 4.0, 3.6 and 3.3. The branches of Dracaena cochinchinensis were inoculated in vivo by some fungi indicated four strains of red Fusarium, F. graminum var. dracaena and so on, play important effect on forming of blood resin in Dracaena cochinchinensis through the effect of yielding blood resin of fungi on Dracaea cochinchinensis. The yield of forming dragon blood resin was increased about 66-120 by them.

Key words: Dracaena cochinchinensis
