Because of significant yield losses caused by fungal pathogens, new efficient and environmentally safe methods pest control are needed, amphiphilic compounds (biosurfactants) produced many microbes considered a good alternative. In the present study, biosurfactants rhizosphere isolate Bacillus mojavensis P1709 were assessed for their ability to protect postharvest cherry tomatoes from decay myc...

The western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), is an endemic herbivore of bitter cherry, Prunus emarginata (Douglas ex Hooker) Eaton, but ∼100 years ago established on earlier-fruiting domesticated sweet cherry, Prunus avium (L.) L. Here, we determined if eclosion times of adult R. indifferens from sweet and bitter cherry differ according to the phenology of...

ABSTRACT Grape and cherry mini tomatoes have been conquering Brazilian consumers due to their sweet taste, practicality of consumption, versatility in culinary use. Therefore, the present work aimed characterize ten grape tomato hybrids based on genetic diversity physical biochemical traits provide information for development new genotypes focused appearance enrichment nutritional factors. The ...

We studied the timing of reproductive maturity of cherry fruit fly, Rhagoletis cingulata (Loew), a key pest of sweet and tart cherries in the eastern United States. To determine when cherry fruit fly females become reproductively mature in managed and natural habitats, we deployed traps in sweet and tart cherry orchards and nearby stands of the ancestral host tree, black cherry. Flies were remo...

Due to the randomicity of the natural growth of tomatoes in greenhouses and different storage days for market needs, it is difficult to find appropriate methodologies for certain ripe-tomato-harvesting robot systems. This paper proposes a novel approach for recognizing ripe tomatoes from the natural background in greenhouses and extracting abscission points after color segmentation for autonomo...

BACKGROUND During harvest and transportation, processing tomatoes are exposed to elevated temperatures, compression and vibration in the harvester and truck, making them prone to bruising. The objective of this study was to determine how bruising and exposure to high temperatures affect pectin methylesterase (PME) activation and the textural quality of tomato juice. RESULTS Tomatoes were both...

Effect of drought stress induced by mannitol on secondary products in callus Golden Sunrise cherry tomatoes were studied vitro. Seeds irradiated with gamma at the doses (0, 20, or 40 Gy), and germinated Murashige Skoog, (MS) basal medium. Callus initiated from cotyledon leaf explants using a combination (2.0 kin + 2.0 IAA mg. l-1) then transferred into MS medium supplemented concentrations 40, ...

A nondestructive optical method for determining the soluble solids content of fresh whole tomatoes was investigated. The method, based upon near infrared spectrophotometric techniques, could predict the soluble solids content of tomatoes (r 5 0.92, SEC 5 0.277Brix). Tomatoes from more than 30 popular fresh market cultivars at stages of maturity from mature green to ripe red fruit were studied.
