摘　　要：为探讨寡聚糖对于魔芋软腐病的抗病促生效果,采用寡聚糖浸种以及叶面喷施寡聚糖的方法进行盆栽实验。结果显示单独施用寡聚糖浸种魔芋葡甘聚糖含量提高1.934 mg/g,但魔芋软腐病相对防效为-67.48%;采取叶面喷施寡聚糖虽然魔芋葡甘聚糖含量仅提高0.927 mg/g,但相对防效提高到-15.76%,此外魔芋蛋白质、叶绿素含量均有所提升。因此叶面喷施寡聚糖可提升魔芋的经济产值,但考虑到盆栽试验的局限性,其试验可重复性与机理待进一步试验研究。To investigate the effect of oligosaccharide on disease resistance and growth promotion of'Konjac'soft rot,a pot experiment was conducted using oligosaccharide seed immersion and leaf spraying.The results showed that the content of Konjac glucan increased by 1.934 mg/g with the application of oligosaccharides,but the relative control effect on soft rot was-67.48%.Although the'Konjac'glucomannan content only improved by 0.927 mg/g with foliar spraying,the relative control effect improved to-15.76%.In addition,the protein and chlorophyll contents of Konjac also increased.The results showed that leaf spraying oligosaccharides enhances the economic value of Konjac;however,considering the limitations of the pot experiment,its repeatability and mechanisms require further investigation.
