a range of 5.5–6.0 with 2 m HCl or NaOH. Harvest. Plant storage roots and all foliage were harvested 120 d after planting. Plants were cut at the base and weighed fresh, and after drying for 72 h at 70 °C. Root samples were separated into three

growing conditions. Storage roots are the principal carbohydrate storage organ in sweetpotato, and each root is a length of adventitious root that forms a localized carbohydrate storage structure. They are defined by their distinctive lateral growth

electrolyte leakage for each sampling date as follows. Randomly sampled storage roots, 160 per sub-plot, were individually placed into glass test tubes (25 × 150 mm) and distributed into eight 40-cell test tube racks, where each rack contained 20 tubes of each

rely on biparental crossing to generate a breeding population. Breeding programs have consistently pursued the following goals: 1) higher storage root yield; 2) storage roots with a consistent spindle-like shape and attractive smooth skin; 3) field and

the United States and Canada are known to use greenhouses and HTs for the production of slips and storage roots ( Coleman, 1995 ; Sand Hill Preservation Center, personal communication; Zvalo, 2017 ). Likewise, greenhouse production of sweetpotato is

transplanting produced greater yields of US#1 storage roots compared with a higher rate. Villordan et al. (2013) reported that lateral root length of storage roots increased substantially as N rates increased from 0 to 50 kg·ha −1 , whereas increasing the N

thin and easily sloughed off of storage roots during harvest, transport, packing, and stocking. At harvest, skinning injury can create entry points for postharvest plant pathogens and allow for increased water loss, often causing roots to shrivel

Yam bean is a legume that forms storage roots ( Sørensen, 1996 ). Roots and tubers produced by legumes have long been recognized as a good food source, and they have been recommended for human nutrition ( FAO, 1979 ). Nonetheless, the use of legume

in French fry processing, uniform, round-shaped storage roots are desirable to reduce nonuniform slices ( Hoque and Saha, 2017 ). Consistency in SRL also is desirable for increased mechanization, leading to overall reduced cost of production ( Tang et
