The quality evaluation of sweetpotatoes is utmost importance during postharvest handling as it significantly impacts consumer satisfaction, nutritional value, and market competitiveness. This study presents an innovative approach that integrates explainable artificial intelligence (AI) with hyperspectral imaging to enhance the assessment three important attributes in sweetpotatoes, i.e., dry matter content, soluble solid firmness. Sweetpotato samples different varieties, including "Bayou...
The number of fibrous roots that develop into storage determines sweetpotato yield. aim the present study was to identify molecular mechanisms involved in initiation root formation, by performing a detailed transcriptomic analysis initiating using next-generation sequencing platforms. A two-step approach undertaken: (1) generating database for transcriptome 454-Roche cDNA library created from pooled samples two types: and roots; (2) comparing expression profiles roots, Illumina Genome...
Hyperspectral imaging (HSI) has become a key technology for non-invasive quality evaluation in various fields, offering detailed insights through spatial and spectral data. Despite its efficacy, the complexity high cost of HSI systems have hindered their widespread adoption. This study addressed these challenges by exploring deep learning-based hyperspectral image reconstruction from RGB (Red, Green, Blue) images, particularly agricultural products. Specifically, different algorithms, such...
Adventitious roots of ‘Beauregard’ and ‘Georgia Jet’ sweetpotato were observed anatomically characterized over a period 60 days storage root development. The majority adventitious sampled at 5 to 7 after transplanting (DAT) possessed anatomical features (five or more protoxylem elements) associated with (86%) (89%) 65 DAT traced directly extant DAT. two varieties, however, differed in the timing which regular anomalous cambia formed. Regular vascular cambium development, i.e., initiation...
This study characterized lateral root (LR) development attributes during the onset of storage (SR) initiation stage in ‘Beauregard’ sweetpotato. SR has been defined as appearance cambia around protoxylem and secondary xylem elements. Our results showed that 20-day-old adventitious roots (ARs) classified SRs had 53% 85% greater mean LR count than pencil (PRs) lignified (LGs), respectively. 78% density relative to PRs LGs, 66% 130% total length lower main (MR)/LR ratio compared with (–38%) LGs...
• Premise of the study: Yield in sweetpotato is determined by number storage roots produced per plant. Storage develop from adventitious (ARs) present stem cuttings that serve as propagation material. Data on origin ARs and effect nodal position AR establishment further development are limited. Methods: We anatomically described root primordium initiation using sections measured primordia formed at different positions light microscopy correlated with length 14 d after planting (DAP). Key...
This study characterized the influence of nitrogen (N) rates and variation in local availability on root architecture as measured by lateral (LR) development attributes during onset storage (SR) initiation stage ‘Beauregard’ sweetpotato adventitious roots (ARs). In N rate experiments, plants grown without fertilizer showed significantly lower values for all LR compared with fertilized plants. Total first- (1LR) second-order (2LR) length increased 78% 2873%, respectively, was from 0 to 50...
It has been shown that virus infections, often symptomless, significantly limit sweetpotato productivity, especially in regions characterized by low input agricultural systems. In sweetpotatoes, the successful emergence and development of lateral roots (LRs), main determinant root architecture, determines competency adventitious to undergo storage initiation. This study aimed investigate effect some plant viruses on architecture attributes during onset initiation ‘Beauregard’ sweetpotatoes...
Greenhouse and field culture systems were used to study the effect of drought conditions on storage root (SR) formation in ‘Beauregard’ sweetpotato ( Ipomoea batatas ). In greenhouse system, was simulated by withholding water for 5 10 days after transplanting (DAT) cuttings dry sand. Control plants received at planting every 3 thereafter. studies, natural selective irrigation impose deprivation during critical SR period. DAT reduced number SRs 42% 66%, respectively, compared with controls....
Genetic uniformity was assessed among sweetpotato ( Ipomoea batatas ) clones propagated through adventitious and nodal procedures. A single sprout each of `Jewel,' `Sumor,' L87-95 used as source clonal plants that were simultaneously conventional procedures a tissue culture-based culture technique. sample 15 decamer primers generated 64 scorable amplified fragments in PCR-based assay, 29 which putatively polymorphic across n = 60 samples (10 adventitiously derived plants/genotype). Within...
A prototype phenology-driven Bayesian belief network (BBN) model, named BxNET, was developed to represent the relationship between fresh market yield (U.S. #1 grade) and agroclimatic variables known influence critical storage root initiation stages in ‘Beauregard’ sweetpotato. This data-driven model from experimental data collected over 3 years of field trials which management were kept as uniform possible. The BBN assuming that soil moisture measured at 15-cm depth not a limiting variable...
Abstract ‘Sierra Sweet’ is an attractive, fresh market tomato ( Lycopersicon esculentum Mill.) developed for high soluble-solids content in ripe fruit, important contributor to flavor. has value as a germplasm source enhanced soluble solids and multiple disease resistance well parent the production of commercial hybrids.
The response and adaption to salt remains poorly understood for beach morning glory [Ipomoea imperati (Vahl) Griseb], one of a few relatives sweetpotato, known thrive under salty extreme drought conditions. In order understand the genetic mechanisms underlying tolerance Convolvulaceae member, genome-wide transcriptome study was carried out in by 454 pyrosequencing. A total 286,584 filtered reads from both stressed unstressed (control) root shoot tissues were assembled into 95,790 unigenes...
The growing demand for sweetpotato French fry and other processed products has increased the need producing storage roots of desired shape profile (i.e., blocky less tapered). Length-width ratio (LW) is current de facto standard characterizing shape. Although LW sensitive descriptive some types variability, this index may be inadequate to measure taper subtle variations. Prior work shown that surface area (SA) volume (VOL) are important descriptors but direct measurement methods tedious,...
(2786) Ipomoea L., Sp. Pl.: 159. 1 Mai 1753 [Convolvul.], nom. cons. Typus: I. triloba typ. prop. L. is the largest (650–900 species, depending on concept adopted) and most iconic genus in Convolvulaceae, a family of c. 1880 species (data from Staples, Convolvulaceae Unlimited, 2012 at: http//convolvulaceae.myspecies.info), including important crop sweetpotato, batatas (L.) Lam. (Tabl. Encycl. 1: 465. 1793), several ornamental commonly known as "bindweeds" or "morning glories" (Wilkin Kew...
The primary objective of this work was to generate species-specific information about root architectural adaptations simulated natural levels arsenic (As) during the establishment phase and onset storage formation in sweetpotato. Cultivars Bayou Belle Beauregard were grown on sand substrate provided with 0.5X Hoagland’s nutrient solution varying As (0, 5, 10, or 15 mg⋅L −1 ). During first experiment, entire systems sampled at days, corresponding key adventitious developmental stages....
Polymorphism analysis and yield tests were conducted among `Jewel' sweetpotato clones [ Ipomoea batatas (L.) Lam] obtained from eight state foundation seed programs. Initially, 38 arbitrary primers generated a total of 110 scorable DNA fragments in sample virus-indexed plants each clone source. The number marker loci scored for primer varied one to with an average 2.89. Twenty-one bands (19.1%) as putative polymorphic markers based on the presence or absence amplified products. Further...
Predictive models of optimum sweetpotato ( Ipomoea batatas ) harvest in relation to growing degree days (GDD) will benefit producers and researchers by ensuring maximum yields high quality.
