摘要:

研究壳聚糖与纳米SiOx以及两者复合处理对脐橙果实采后主要侵染性病害青、绿霉病和炭疽病的控制效果,并初步探讨其抗病机制。以脐橙果实为材料,采收后用不同质量浓度壳聚糖与纳米SiOx溶液浸泡处理1 min,研究壳聚糖与纳米SiOx处理对果实青、绿霉病和炭疽病自然发病情况的影响;同时,通过不同时间损伤接种病原菌,研究壳聚糖与SiOx处理对果实青、绿霉病和炭疽病的控制效果。结果显示:1.5 g/100 mL壳聚糖复合0.08 g/100 mL SiOx处理控制采后脐橙果实青、绿霉病和炭疽病的自然发病效果最好,同时降低了接种病原菌果实的发病率和病斑直径,效果明显优于壳聚糖与SiOx单独处理。

Abstract:

The aim of this study was to investigate the effects and mechanism of chitosan, SiOx and their combination on
postharvest disease control of navel orange. After harvest, navel oranges were dipped into different solutions containing
either or both of chitosan and SiOx for 1 min. The influences of chitosan and SiOx treatments on natural incidence of diseases
of navel oranges were detected. Besides, the effects of chitosan and SiOx treatments on diseases control by changing the
order of inoculating pathogens were also investigated. The results showed that 1.5 g/100 mL chitosan combined with
0.08 g/100 mL SiOx exerted the most significant inhibition on natural diseases incidence, decreased the diseases incidence
and reduced the lesion diameter of navel oranges inoculated with pathogens. Compared with either treatment alone, the
combined treatment with chitosan and SiOx was more effective.

Key words: chitosan, SiOx, navel orange, disease control
