中文摘要:

      目的 以喷施4种杀菌剂防治马铃薯Y病毒病的样品为试验原料, 研究防效与干物质、淀粉、还原糖和维生素C含量之间关系, 分析各营养成分之间的相关性。方法 在国家标准基础上稍加改动测定营养成分, 采用矩阵散点图、标准化残差P-P图、一元线性回归分析防效与营养成分及各营养成分之间的相关性。结果 防效与干物质、维生素C和淀粉含量之间呈正相关, 干物质含量与淀粉含量、维生素C呈正相关, 维生素C含量与淀粉含量呈正相关, 还原糖含量与维生素C含量、淀粉含量、干物质含量和平均防效四者之间无显著相关性。结论 4种杀菌剂中防效最好的为喷施5%氨基寡糖素水剂中剂量, 且采收该小区马铃薯干物质含量、淀粉含量和维生素C含量最高。研究结果可为种植马铃薯防治Y病毒病筛选最佳药剂, 为马铃薯病害防治与营养成分之间相关性提供数据支撑。

英文摘要:

      Objective To study the relationship between control effect and content of dry matter, starch, reducing sugar and vitamin C, and analyze the correlation between the nutrients, using the samples sprayed with 4 fungicides against Solanum tuberosum virus Y disease as test materials. Methods On the basis of the national standard, the nutritional components were determined with a little modification, the correlation between the control effects and nutrient composition and each nutrient ingredient were analyzed by matrix scatter plot, standardized residual P-P plot and unary linear regression. Results The control effect was positively correlated with dry matter content, vitamin C content and starch content, dry matter content was positively correlated with starch content and vitamin C content; vitamin C content was positively correlated with starch content; while there was no significant correlation between reducing sugar content and vitamin C content, starch content, dry matter content and average control effects. Conclusion Among the 4 kinds of fungicides, the best control effect is spraying 5% amino-oligosaccharide at the medium dose, and the Solanum tuberosum dry matter content, starch content and vitamin C content are the highest in the harvesting plot. Research results can be used to screen the best pesticides for planting Solanum tuberosum to prevent and control Y virus disease, provide data support for the correlation between Solanum tuberosum disease control and nutritional components.
