【摘要】 贮藏是甘薯生产过程中不可或缺的关键环节。为了探索在生产上判断品种耐储性的指标以及筛选适合豫中南地区贮藏的甘薯新品种，以豫中南地区10个优良栽培品种为研究对象，测定贮藏前后失重率、单块薯重变化、干物质消耗率、水分消耗率、商品薯率变化以及干物率的变化情况，开展耐储性研究。结果显示，失重率与商品薯率呈极显著负相关，是衡量甘薯品种耐储性的一个直观快捷的指标；兼用型甘薯、紫薯型甘薯品种的耐贮性要高于食用型甘薯品种；整个贮藏期间干物率变化的主要原因是品种间差异,能解释88.49%的变异；漯薯11号、漯薯15号、漯薯16号是适宜豫中南地区贮藏的加工型甘薯品种；烟薯25号、商薯19、漯紫薯4号、漯紫薯5号是适宜在豫中南地区贮藏的食用型、紫薯型甘薯品种。更多还原

【Abstract】 Storage is an indispensable key link in sweet potato production. To explore indicators for evaluating the storage tolerance of varieties in production and to select new sweet potato varieties suitable for storage in the central-southern Henan, ten superior cultivars from this area were used as research subjects. Measurements were taken before and after storage, including weight loss rate, changes in individual tuber weight, dry matter consumption rate, moisture consumption rate, changes in marketable tuber rate, and changes in dry matter rate, to study storage tolerance. The results showed that weight loss rate was significantly negatively correlated with marketable tuber rate, making it an intuitive and rapid indicator for assessing the storage tolerance of sweet potato varieties. The storage tolerance of dual-purpose and purple-fleshed sweet potato varieties was higher than that of edible varieties. The primary factor influencing changes in dry matter rate during the entire storage period was inter-varietal differences, accounting for 88.49% of the variation. Luoshu No. 11, Luoshu No. 15, and Luoshu No. 16 were identified as processing type sweet potato varieties suitable for storage in the central-southern Henan, while Yanshu No.25, Shangshu No.19, Luozishu No.4, and Luozishu No.5 were found to be edible and purple-fleshed sweet potato varieties suitable for storage in this area.更多还原
