前言萎蔫病是非洲最严重的油棕病害,致病真菌为油棕尖镰孢(Fusarium oxysporum F·sp·elaeidis),是1946年首次分离出来的。此菌在象牙海岸热带草原区以及森林地带引起极大危害,在各种环境下都是扩种油棕的一大威胁。由于杀菌剂处理在技术上和经济上不可能大面积进行,尤其是发现杂种间药效有明显的差异,致使法国海外油料油脂研究所从遗传学上寻找解决萎蔫病问题的办法。病原菌接种和过渡苗圃中早期测验的成功进展都
Introduction Wilt disease is the most serious oil palm disease in Africa. The pathogenic fungus Fusarium oxysporum F · sp. Elaeidis was isolated for the first time in 1946. This bacterium causes great harm in the Ivory Coast’s savannah zone and forested areas, and is a major threat to the expansion of oil palm in all environments. As the biocide treatment is not technically and economically feasible, in particular the discovery of significant differences between the efficacy of hybrids, resulting in the French Institute of Oil Fats genetically looking for ways to solve the problem of wilting. Pathogens inoculation and transitional nurseries in early trials have been successful
