| 摘 要： | 尖孢镰刀菌西瓜专化型[Fusarium oxysporum Sch l.f.sp.niveum(E.F.Smith) Snyder et Hansen]菌株在4种培养基(理查德培养基,Armstrong镰刀菌培养基,MS无机盐+蔗糖培养基,PDB培养液)中均能产生镰刀菌酸(Fusaric acid),理查德培养基中镰刀菌酸最高时的浓度是其它3种培养基的6~22倍。理查德培养基以C/N为5:1,葡萄糖为C源,NO-3为N源的营养条件较有利于镰刀菌酸产生。培养基初始pH值为4,通气和连续光照的培养条件最有利于菌株产生镰刀菌酸,烟酸的加入可终止镰刀菌酸产生。各培养基中孢子浓度与镰刀菌酸浓度之间呈负相关的变化趋势,培养基的pH值呈趋中(pH6~8)变化,与镰刀菌酸产生无相关性。在理查德培养基中,菌丝生长与镰刀菌酸产生之间存在平行关系。 |

| Abstract: | Fusaric acid production in the strains of Fusarium oxysporium Schi. f. sp. niveum (E. F. Smith) Snyder et Hansen was tested in four different liquid media, Richard's liquid medium, MS salt+ sugar liquid medium, Armstrong liquid medium for Fusarium and PDB liquid medium. Fusaric acid is produced in all the four media but varies in yield with the media. |
| Keywords: | Fusarium wilt Fusaric acid Cultural condition |
