ABSTRACT African yam bean (AYB; Sphenostylis stenocarpa Hochst. Ex A. Rich.) is an underutilized legume indigenous to Africa. The crop has great potential as it can enhance food security and its chemical composition offers nutritional medicinal opportunities. However, the low grain yield caused by fungal diseases, including pod blight leaf tip dieback, deters farmers from large-scale cultivation. causal agents of dieback on AYB are largely uncharacterized. To determine prevalence diseases...

Abstract Tuber dormancy and sprouting are commercially important potato traits as long-term tuber storage is necessary to ensure year-round availability. Premature release sprout growth in tubers during can result a significant deterioration product quality. In addition, the main chemical suppressant chlorpropham has been withdrawn Europe, necessitating alternative approaches for controlling sprouting. Breeding cultivars with longer slower desirable goal, although this must be tempered by...

Supplying atmospheres with partial pressures of O 2 as low 0.4 kPa in combination up to 5 CO has proved an effective alternative the use post-harvest chemical treatments, e.g. diphenylamine, for control superficial scald 'Bramley's Seedling' apples. However, such 'extreme' CA conditions occasionally caused injury skin and flesh fruit, risk holds back these techniques replace treatments. Working on hypothesis that is by a transient high concentration fruit shortly after store loading, we...

Abstract African yam bean (AYB; Sphenostylis stenocarpa ) is an underutilized legume indigenous to Africa with great potential enhance food security and offer nutritional medicinal opportunities. However, low grain yield caused by fungal diseases, including pod blight leaf tip dieback, deters farmers from large‐scale cultivation. To determine the prevalence of diseases affecting leaves, pods flowers AYB, a survey was conducted in 2018 2019 major AYB‐growing areas Nigeria. Leaf flower bud rot...

A diverse assemblage of insect visitors can provide functional complementarity within plant pollination due to differences in characteristics such as their physical traits, visitation rate and foraging time day or year. In a horticultural context, greater may play crucial role enhancing fruit yield quality by improving pollination. We tested whether the identity crop pollinators (bumblebee Bombus terrestris hoverfly Eupeodes corollae) independently additively influenced commercial strawberry...

Fruit firmness and in particular the individual components of texture moisture loss, are considered key quality traits when describing blueberry fruit quality, whilst these genetically regulated, mechanisms governing their control not clearly understood. In this investigation, RNAseq was performed on fruits two cultivars with very different storage properties, ‘Bluecrop’ ‘Legacy’, at harvest, three weeks a non-modified environment 4 °C after followed by days 21 °C, aim understanding...

Bitter pit is an important physiological disorder of apple that can develop on the tree but most prevalent during storage. Delaying fruit maturation after harvest through controlled atmosphere storage and application 1-MCP SmartFreshTM) delay onset symptoms; however, significant losses may occur in long-term stored apples. It hard to detect internal bitter using external examination alone. Current predictive methods are based destructive quality assessments mineral analysis. A...

Bioimpedance spectroscopy is the electrical impedance of a biological sample measured over range different frequencies. Over kHz to MHz range, characteristic shape spectra denoted as β dispersion, and result polarisation cell boundaries presenting capacitance that contributes overall flow current in sample. This implies curve dispersion could be marker for breakdown behaviours vitality within fruit, variations walls (looseness or death) will present capacitances.In this paper, we some early...
