摘要
在室温条件下,用3种植物提取物2号、5号和12号的不同浓度处理对桃果实采后褐腐病防治效果进行了探讨。结果表明,与仅接种褐腐病菌(M.fracticola)的对照(ck)相比,提取物2号的3个浓度处理均能显著抑制褐腐病菌对桃果实的侵染(P<0.01),并且浓度越高抑制效果越明显,其中用50mg/mL浓度处理的桃果实腐烂率为0;提取物5号处理也能显著抑制桃果实采后褐腐病的发生,用12.5mg/mL浓度处理的防治效果最佳,腐烂率也为0;提取物12号的3个浓度处理得到的果实病斑直径基本相同,而发病率是随着提取物浓度的升高而明显降低,但总体效果均显著好于ck(P<0.01)。
The inhibitory effects of three plant extracts--No.2,No.5 and No.12-on Monilinia.fracticola rot of harvested peach fruits were studied respectively. All fruits were stored at 25 ℃ after treatments. The results showed that, Compared with inoculated treatment with M. fracticola alone(ck), three concentrations of plant extract No.2 were significantly effective in reducing decay incidence and severity of Monilinia. fracticola rot in peach fruits, especially the decay incidence of fruits treated by 50 mg/mL concentration was zero(P<0.01)The higher the concentration, the more significant of the effect. Different concentrations of plant extract No.5 also showed the significantly inhibitory effects (P<0.01), and there were not rotten fruits with the dose of 12.5 mg/mL. Plant extract No.12 also remarkably suppressed the lesion extension,though three lesion diameters were same(P<0.01=.
