摘要: 研究了枯草芽孢杆菌B1(Bacillas subtilis)结合苯丙塞重氮(BTH)处理或它们单独使用对甜瓜采后主要病害的生物防治效果。结果表明:所有处理都降低了Alternaria alternata、Rhizopus stolonifer、Fusarium semitectum的发病率。对于Thrichothecium roseum,B1结合BTH和B1单独处理明显降低了病斑直径;对于A.alternata,BTH单独处理和结合使用的效果较好;对于R.stolonifer,B1结合BTH和B1单独处理的效果较好;对于F.semitectum,结合使用的效果较好。研究结果还显示,BTH、B1及结合处理均能诱导甜瓜的过氧化物酶(POD)活性和几丁质酶(CHT)活性的升高,并且可以持续8d。

Abstract: Biocontrol effects of benzothiazole (BTH) and Bacillas subtilis B1 tagether treatment or respective treatment on major postharvest diseases of muskmelon were studied. The results indicated that all treatments decrease the infection incidence of A. alternata, R.stolonifer, F. semitectum. B1 and BTH or only B1 treatment inhibits the lesion diameter of T.roseum signifcantly. For A.alternata, B1 and BTH or BTH treatment is optimal. B1 and BTH or B1 treatment inhibits the lesion diameter of R.stolonifer signifcantly. B1 and BTH treatment is optimal for F. semitectum. The results also showed that B1, BTH, B1 and BTH significantly induce the peroxidase (POD) activity and chitinase (CHT) activity of muskmelon compared with control. The activity sustaines for at least 8 days at room temperature.
