[目的]为明确壳聚糖与有机硅对番茄抗灰霉病菌能力的影响。[方法]采用叶面喷施法，通过测定在4个处理下，即空白对照、灰霉病菌处理、壳聚糖＋灰霉病菌处理、壳聚糖＋有机硅＋灰霉病菌处理，番茄的抗氧化酶活性来研究壳聚糖和有机硅对番茄抗氧化酶活性的影响。【结果]壳聚糖＋有机硅＋灰霉病菌处理组和壳聚糖＋灰霉病菌处理组与灰霉病菌处理相比可提高番茄幼苗叶片中抗氧化酶活性，在第6天，壳聚糖＋有机硅＋灰霉病菌处理组和壳聚糖＋灰霉病菌处理组的PAL、SOD、POD、PPO、CAT活性比灰霉病菌处理组分别提高27．36％、52．07％、43．55％、82．02％、71．82％和18．91％、30．22％、57．14％、38．09％、53．64％。[结论]壳聚糖和有机硅可增加番茄幼苗感染灰霉病后抗氧化酶的活性。

[Objective] The aim was to explore effects of chitosan and organosilicon on tomato resistance against Botrytis cinerea. [Method] With leaf spraying method adopted, four groups were set in the test, including control group, groups treated with Botrytis cinerea, with chitosan and Botrytis cinerea, and with chitosan, organosilicon, and Botrytis cinerea, in order to study on effects of chitosan and organosilicon on antioxidant enzyme activities of tomato. [Result] Antioxidant enzyme activities of tomato seedlings were improved in groups with chitosan, organosilicon, and Botrytis cinerea and with chitosan and Botrytis cinerea compared with the group treated with Botrytis cinerea. On the 6th d, activities of PAL, SOD, POD, PPO and CAT in groups with chitosan and Botrytis cinerea, and with chitosan, organosilicon, and Botrytis cinerea increased by 27.36%, 52.07%, 43.55%, 82.02% and 71.82%, and 18.91%, 30.22%, 57.14%, 38.09% and 53.64%, respectively. [Conclusion] Antioxidant enzyme activities of tomato seedlings could be improved by chitosan and organosilicon.
