BACKGROUND Postharvest application of fungicide prochloraz and hot-water dip are commercially practiced to control postharvest diseases in mangoes. Owing to the increasing consumer demand for organically produced fruit, the search for natural environmentally friendly alternative products and processes has become important for the fruit industry. This study evaluated the combined effect of 1-met...

Although the potential of marker-assisted selection (MAS) in fruit tree breeding has been reported, bi-parental QTL mapping before MAS has hindered the introduction of MAS to fruit tree breeding programs. Genome-wide association studies (GWAS) are an alternative to bi-parental QTL mapping in long-lived perennials. Selection based on genomic predictions of breeding values (genomic selection: GS)...

An on-farm study was conducted among smallholder mango farmers in Embu County of Kenya to demonstrate the effectiveness simple harvest and postharvest handling practices attain cold chain extend shelf life. The recommended were compared with common farmers' practices. 'Apple', 'Ngowe', 'Kent', 'Tommy Atkins' harvested at mature green stage used study. To proper chain, fruits before 8 am, transp...

We investigated the effects of melatonin (MT) treatment on physiological quality and cell wall metabolism kiwifruit during a 12-day shelf life period (20 ± 1 °C, 90 5% RH), after days cold storage (0 0.5 RH). Our results showed that MT delayed softening, as evidence by enhanced endurance healthy appearance, quality, color difference L* value, firmness fruit flesh. reduced decay rate, respiratio...

Although acerola (Malpighia emarginata D.C.) has been suggested to be a climacteric fruit, little is known about its sensitivity exogenous ethylene. The objective of the study was evaluate quality changes fruit at two harvest maturity stages in response external ethylene application. ‘Flor Branca’ and ‘Junko’ acerolas were harvested 1 (green with density>1 g cm-3) 2(green density <1 treated 0 o...

Air impingement (AI) thawing was studied as alternative to time-consuming thawing, conventionally performed in refrigerators for food service. Chicken fingers’ bags (200 g), surrounded by Tylose simulate a service grid load, were thawed an AI prototype. Nine combinations of process parameters (distance nozzles, air speed, temperature, number stages, and stage durations) identified genetic algor...

Texture is an important attribute affecting consumer perception of fruit quality. Peach melting flesh and flesh adhesion to stone (endocarp) are simply inherited and controlled by the F-M locus on linkage group (LG) 4. Here, we report that two genes encoding endopolygalacturonase (endoPG) in the F-M locus, designated PpendoPGF and PpendoPGM, are associated with the melting flesh and stone adhes...

Loquat (Eriobotrya japonica Lindl.) can be sorted into red- and white-fleshed cultivars. The flesh of Luoyangqing (LYQ, red-fleshed) appears red-orange because of a high content of carotenoids while the flesh of Baisha (BS, white-fleshed) appears ivory white due to a lack of carotenoid accumulation. The carotenoid content in the peel and flesh of LYQ was approximately 68 μg g(-1) and 13 μg g(-1...

The high postharvest losses (40 – 50%) reported in the mango value chain are partly attributed to lack of reliable maturity indices. Harvest is dictated by intended use and target market for fruits. aim this study was establish indices three commercial varieties namely ‘Van dyke,’ ‘Kent’ ‘Tommy Atkins’ Embu County Kenya. At least eighteen trees (six per variety) were randomly tagged at 50% flow...

This study reports the first observations indicating the spatiotemporal relationships among genetic and physiological aspects of ripening in the berry of Vitis vinifera. At the onset of ripening in the red flesh variety Alicante Bouschet, colour development began in the flesh at the stylar end of the fruit and progressed toward the pedicel end flesh and into the skin. Tissue solute potential an...
