Abstract
Isolate RS-S-3 of Fusarium oxysporum f. sp. raphani and isolate FnC-B of F. oxysporum f. sp. niveum were selected for the study because of their low percentage germination of conidia and chlamydospores and high percentage lysis of germ tubes on soil amended with S-H mixture. S-H mixture was more effective in inhibiting spore germination at high pH than at low pH in nutrient solution.
本研究中所用之蘿蔔黃葉菌RS-S-3菌株及西瓜蔓割病菌FnC-B菌株，在添加S-H混合物之土中，均有分生胞子及厚膜胞子發芽率低及發芽管易於瓦解之特性，以此特性可以測知S-H添加物中之抑病機制。在鹼性營養液中，S-H添加物抑制胞子發芽之效力高。S-H添加物中之礦灰及蚵殼粉為分解蘿蔔黃葉病菌發芽管及抑制後膜胞子發芽之主要成分，而礦灰為分解西瓜蔓割病菌發芽管之主要成分。
