| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
