BACKGROUND Increasing antioxidant levels in fruit through breeding is an important option to support higher antioxidant intake particularly when fruit consumption is low. Indeed, if nutritional components are also combined with a high standard of sensorial fruit quality, the perspective for consumer health can be further improved by encouraging more fruit consumption. Wild species are valued by...

Twenty Citrus cultivars grown in the Mediterranean climate were analysed at different stages of fruit maturity to determinate changes in organic acids, vitamin C and sugars. High-performance liquid chromatographic methods were used to identify and quantify of these compounds. The influences of variety, rootstocks and different stages of fruit maturity were observed. Generally, the vitamin C con...

In this study, the aim is to develop a population model based approach to optimize fruit harvesting strategies with regard to fruit quality and its derived economic value. This approach was applied to the case of tomato fruit harvesting under Vietnamese conditions. Fruit growth and development of tomato (cv. "Savior") was monitored in terms of fruit size and color during both the Vietnamese win...

In this experiment (in the absences of disease pressure) the application of Mycostop had no effect on yield or quality of fruit harvested. Nutrient and irrigation application based on the amount of solar radiation received by the crop reduced the amount of nutrient used without reducing yield or quality. Fruit quality was higher with lower amounts of irrigation but yield increased with increase...

awareness of the effects of water deficit on quality and quantity yield of orange is essential for product managing at water shortage conditions. in this regard, present study was conducted in an orange garden of babol area in 2011 in a completely randomized design with 5 treatments and 5 replications. experiment treatments included full irrigation (fi), regulated deficit irrigation (rdi) and p...

Potassium (K+ ), an abundant cation in plant cells, is important in fruit development and plant resistance. However, how cellular K+ is directed by potassium channels in fruit development and quality formation of strawberry (Fragaria × ananassa) is not yet fully clear. Here, a two-pore K+ (TPK) channel gene in strawberry, FaTPK1, was cloned using reverse transcription-PCR. A green fluorescent p...

the effects of different stages of maturity (mature green, until 20 to 40% of change in color), two treatments of cool water (5 ?c for 5' and 10 ?c for 15min.), two treatments of hot water (50 ?c for 15 min. and 55 ?c for 5 min.) ), two temperatures (10 and 14 °c) of storage vs. six time periods (0, 5, 10, 15, 20 and 25 days) on shelf life and storage time of ‘langra’ mango fruit were stud...

Irrigation with moderate salinity stress in a hydroponic system improves the inner and outer fruit quality of tomato (Solanum lycopersicon Mill. ‘House Momotaro’). We investigated the effects of 50 mM NaCl in a hydroponic solution on the levels of various metabolites, including soluble sugars, amino acids, and organic acids, and on the expression levels of salinity-responsive genes during fruit...

abstract in order to provide optimal yield and quality of tomato fruit (lycopersicon esculentum mill. cv. beril), different growing media for soilless culture of tomato plants were studied. seedling of tomato (lycopersicon esculentum mill, cv. beril ) were cultivated in perlite, mixture of perlite with nh4-zeolite and with raw zeolite (z:p ratio 10v:90v) and fed by two nutrient sources: a) comp...

Successful completion of fruit developmental programs depends on the interplay between multiple phytohormones. However, besides ethylene, the impact of other hormones on fruit quality traits remains elusive. A previous study has shown that down-regulation of SlARF4, a member of the tomato (Solanum lycopersicum) auxin response factor (ARF) gene family, results in a dark-green fruit phenotype wit...
