摘要
研究了2种不同壳聚糖（水溶性壳聚糖CS1、酸溶性壳聚糖CS2）对油茶炭疽病菌的抑制作用．结果表明：这2种壳聚糖均对油茶炭疽病菌有明显的抑制作用，且随壳聚糖浓度的增大而抑菌活性增强；在pH5．3～6．0环境中抑菌效果最优，最佳酸溶剂为酒石酸和醋酸；2．50mg·mL^-1CS1＋1％HAc对油茶炭疽病菌抑制率为71．6％，抑制作用几乎与500倍甲基托布津等效．壳聚糖是甲壳素脱去乙酰基的产物，无毒无害，可生物降解，又具有较强抑菌作用，可望开发为一种新型的环保农药．
Two different chitosans have been investigated for their anti fungal activities against Colletotrichurn gloeosporioides in Camellia oleije in vitro. The results indicate that the two chitosans have strong anti-fungal activities which increase with the increase of concentration; and that the optimum anti-fungal activities are produced in an environment whose pH value is 5.3-6.0 and the optimum solvents are tartaric acid and acetic acid. Chitosans can he developed to be a new type of environmentally friendly pesticide.
