Fruits of kiwifruit cultivars (Actinidia chinensis and A. deliciosa) generally have green or yellow flesh when ripe. A small number of genotypes have red flesh but this coloration is usually restricted to the inner pericarp. Three kiwifruit cultivars having red ('Hongyang'), or yellow ('Jinnong-2'), or green ('Hayward') flesh were investigated for their color characteristics and pigment content...

Softening, a common phenomenon in many fruits, is a well coordinated and genetically determined process. However, the process of flesh softening during ripening has rarely been described in hawthorn. In this study, we found that 'Ruanrou Shanlihong 3 Hao' fruits became softer during ripening, whereas 'Qiu JinXing' fruits remained hard. At late developmental stages, the firmness of 'Ruanrou Shan...

The tolerance of ‘Apple’ banana (Musa sp.), avocado (Persea americana Mill.), mango (Mangifera indica L.), papaya (Carica papaya L.), and red ginger (Alpinia purpurata (Vieill.) K. Schum) inflorescences to carbonyl sulfide (COS) fumigation was studied. Commodities were exposed at 25°C to COS at various concentrations (1–6% (v/v) for banana; 1% and 2% for the other fruits for various times from ...

BACKGROUND Tomatoes provide a significant dietary source of the carotenoids, lycopene and β-carotene. During ripening, carotenoid accumulation determines the fruit colors while chlorophyll degradation. These traits have been, and continue to be, a significant focus for plant breeding efforts. Previous work has found strong evidence for a relationship between CYC-B gene expression and the orange...

In this study the abundance and location of phosphoenolpyruvate carboxykinase (PEPCK) was determined in the flesh and skin of the sweet cherry (Prunus avium L.) cultivar Durone Nero II during development. PEPCK was not present in young fruit but appeared in both tissues as the fruit increased in size. In these there was no net dissimilation of malic acid, which accounts for the bulk of their or...

The objective of this paper was to evaluate the effect time summer pruning on quality Fuji apples, red color and functional properties, at harvest after 3.5 months cold storage. treatments evaluated consisted control (without pruning) in December, January, February. percentage fruit with more than 50% skin 20.5% higher when performed later early. In general, January February provided a relative...

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...

peach genotypes showing notable fruit and tree traits were selected in ardabil and east azarbaijan provinces of iran. genotypes were grafted on seed rootstocks and cultured with 4×4 m spacing. traits such as tree growth habit, flowering, maturity, morphological and qualitative fruit characteristics were described in 15 peach genotypes using ibpgr peach descriptors during the 2005-2007 seasons. ...

To identify the genetic factors underlying the regulation of fruit vitamin C (L-ascorbic acid [AsA]) concentrations, quantitative trait loci (QTL) studies were carried out in an F1 progeny derived from a cross between the apple (Malus × domestica) cultivars Telamon and Braeburn over three years. QTL were identified for AsA, glutathione, total antioxidant activity in both flesh and skin tissues,...

BACKGROUND Ripening of fleshy fruit is a complex developmental process involving the differentiation of tissues with separate functions. During grapevine berry ripening important processes contributing to table and wine grape quality take place, some of them flesh- or skin-specific. In this study, transcriptional profiles throughout flesh and skin ripening were followed during two different sea...
