摘要

用硝酸水解壳聚糖；主要部分具有30kDa的分子量和95%的脱乙酰度。研究了壳聚糖水解产物以不同浓度（0.5、1、1.5、2、4、6和8mg/mL）加入马铃薯葡萄糖琼脂（PDA）中对真菌Alternaria solani Sorauer、Fusarium solani（Mart.）Sacc生长的影响。和Rhizoctonia solani J.G.Kühn。在放射状生长实验中，A.solani对PDA中添加壳聚糖水解物最敏感。在培养的第3天和第7天，在0.5-2mg/ml的浓度范围内，植物病原体生长的抗真菌活性分别为69%-92%和69%-88%。

THE EFFECT OF CHITOSAN HYDROLYSATE ON THE FUNGI ALTERNARIA SOLANI, FUSARIUM SOLANI AND RHIZOCTONIA SOLANI IN VITRO

Chitosan hydrolysate was obtained using nitric acid; the prevailing fraction had a molecular weight of 30 kDa and a deacetylation degree of 95%. The effect of chitosan hydrolysate when added to potato dextrose agar (PDA) in different concentrations (0.5, 1, 1.5, 2, 4, 6 and 8 mg/mL) was studied on the growth of the fungi Alternaria solani Sorauer, Fusarium solani (Mart.) Sacc. and Rhizoctonia solani J.G. Kühn. A. solani was the most sensitive to the addition of chitosan hydrolysate to PDA in radial growth experiments. On days 3 and 7 of incubation, the antifungal activity of the phytopathogen growth was 69%-92% and 69%-88%, respectively, in the concentration range of 0.5-2 mg/ml.
