摘要
本研究的目的是(1)评价不同盐对茄蓝镰刀菌(Fusarium solani var. coeruleum)离体发育的影响;(2)评价不同盐对马铃薯块茎干腐病的缓解效果。研究表明,几种盐类对茄蓝病菌菌丝生长有明显的抑制作用。乙酸铝、氯化铝、苯甲酸钠、焦亚硫酸钠、山梨酸钾和磷酸三钠完全抑制菌丝生长。在0.2 M条件下,番茄蓝斑枯病菌分生孢子暴露于乙酸铝、山梨酸钾、苯甲酸钠、焦亚硫酸钠或磷酸三钠,1 h后死亡率为100%,而氯化铝和乳酸铝暴露24 h后死亡率为100%。用不同的盐处理接种了蓝斑番茄的块茎,并在7 d的孵育期后评估病害的严重程度。在试验盐中,只有氯化铝与对照相比显著降低了马铃薯干腐病的发生。指出了利用氯化铝防治马铃薯干腐病的可能性。
Effect of different salts on the development of Fusarium solani var. coeruleum, a causal agent of potato dry rot
The objectives of this study were (1) to evaluate the effect of different salts on the in vitro development of Fusarium solani var. coeruleum, and (2) to evaluate the efficacy of the salts for reducing dry rot severity caused by the pathogen in potato tubers. The study showed that several salts significantly inhibited the mycelial growth of F. solani var. coeruleum. Aluminium acetate, aluminium chloride, sodium benzoate, sodium metabisulfite, potassium sorbate and trisodium phosphate completely inhibited mycelial growth. Exposure of F. solani var. coeruleum conidia to aluminium acetate, potassium sorbate, sodium benzoate, sodium metabisulfite or trisodium phosphate at 0.2 M resulted in 100% mortality of the conidia after 1 h while aluminium chloride and aluminium lactate caused 100% mortality after an exposure of 24 h. In order to evaluate the effect of salts on potato dry rot development, F. solani var. coeruleum-inoculated tubers were treated with the different salts and disease severity was evaluated following an incubation period of 7 d. Among the test salts, only aluminium chloride caused a significant reduction in potato dry rot compared with the control. The study points out the possibility of using aluminium chloride to control potato dry rot.
