consumers prefer seedless grapes for table and raisin grape industry. release of new superior seedless grape cultivars is one of the main objectives in grape breeding programs. embryo rescue is one of the techniques to develop a new seedless cultivar. therefore, in this study, the effects of bud flower spraying with ba (50 ppm) and ccc (200 ppm) before blooming were studied in ‘flame seedless’ ...

Grapes are widely known for health benefits due to their antioxidant content. In wine production, grape stems are often discarded, though they has a higher content of antioxidants than the juice. The effectiveness of using an environmentally friendly solvent, ethanol, as a superheated liquid and supercritical fluid to extract antioxidant compounds from grape stems of organically grown Crimson S...

An evacuated tube solar collector drier is designed and developed to study analytically and experimentally drying kinetics of Thompson seedless grapes in Pune, India. Drying experiments are carried out in the month of April- June for continuous three years from 2013-2015. During the experimentation, temperatures of hot and cold air at various places, ambient relative humidity and humidity varia...

BACKGROUND The phytohormone gibberellic acid (GA3) is widely used in the table grape industry to induce seedlessness in seeded varieties. However, there is a paucity of information concerning the mechanisms by which GAs induce seedlessness in grapes. METHODOLOGY/PRINCIPAL FINDINGS In an effort to systematically analyze the cause of this GA3-induced seed abortion, we conducted an in depth char...

Gibberellic acid (GA3) is the most widely used plant growth regulator to thin out bunches and increase berry size in seedless table grapes, but there evidence of its negative effects, including loss fertility malformations rachis. This study analyses effects applying auxin indole-3-butyric (IBA), as a novel alternative, on fruit yield, bunch structure, anatomy postharvest quality cv. Superior S...

Microwave vacuum drying has been investigated as promising potential for high-quality dried fruits. In this study, a batch microwave vacuum dryer was used to understand the effect of levels of microwave power on the drying characteristics and moisture content of grapes. Thompson seedless grapes were treated 1st for 30, 60, and 90 min at fixed levels of 500, 750, 1000, 1250, and 1500 W at a redu...

Silwet L-77, an organosilicone surfactant, was applied to several arthropod pests of California table grapes. Eggs of grape mealybug, Pseudococcus maritimus (Ehrhorn), and omnivorous leafroller, Platynota stultana Walsingham, were tolerant to 0.1, 0.25, and 0.5% treatment solutions; however, eggs of Pacific spider mite, Tetranychus pacificus McGregor, were highly susceptible with mortality >99....

This study was carried out to determine the effects of different openings onto polyethylene (PE) packages used in storage ‘Sultani Çekirdeksiz’ grape variety on quality, SO2 damage, pathological and physiological disorders grapes. Grapes were harvested at full maturity placed PE bags with ‰0 (control), ‰0.5, ‰1 ‰2 openings. After pre-cooling grapes case pets after mouth closed. stored 0°C 90-95...
