Abstract
本研究已證明本省亞麻栽培地區有鐮刀菌萎凋病抑病土壤之存在。「抑病土壤」內 Fusarium oxysporum f. sp, limi 菌體增加速度緩慢，厚膜胞子發芽率低，發芽管短，而且發現有溶菌現象；細菌聚集在發芽管和厚膜胞子周圍。這些細菌是否導致溶菌原因，有待繼續研究。
It has been prover that there are two different kinds of soils in flax fields; one is wilt-conductive and the other is wilt-suppressive. Fusarium oxysporum f. sp. limi multiplies rapidly, and its chlamdos-pores germinate normally in the wilt-conducive soil. On the other hand , the pathogen multiplies slowly, and its chlamydospores are rather difficult to germinate, and even if they germinate the germ tubes are short and always surrounded with bacteria resulting the lysis of germ tubes in the wilt-suppressive soil.
