in order to evaluation of squash (cucurbita pepo) seed yield per fruit and its relations with other characteristics of fruit include: length, diameter, length: diameter ratio (fruit shape), flesh thickness, thousand seed weight and fruit weight, an experiment was conducted using 24 accessions of squash as a randomized complete-block design with three replications. morphological traits were eval...

The aim of this study was to evaluate the effects of foliar application of boron and calcium on postharvest storage characteristics of Asian pear (Pyrus pyrifolia) fruit. This experiment was carried out in the experimental orchard of Asian pear at Tarbiat Modares University, Tehran, Iran. The treatments were two concentrations of boric acid (0% and 0.5%) and three concentrations of calcium chlo...

Automated grading of fruit is an important industrial task that is expanding rapidly in its uptake. Machine learning-based techniques are increasingly being applied to this domain in order to formulate effective solutions for complex classification tasks. The inherent variability in the visual appearance of fruit and its quality-determining features, contributes to it often being a challenging ...

The characteristics of fruit ripening and expression of ripening-related genes were investigated in epi, an ethylene overproduction mutant of tomato (Lycopersicon esculentum Mill.). The epi produces apparently more ethylene than its wild type VFN8 at every stage of vegetative and fruit growth and ripening; compared to VFN8, the epi fruit showed higher CO2 evolution, faster descending of chlorop...

Fruit quality of five scab resistant apple cultivars (Enterprise, Liberty, Nova Easygro, Sir Prize and Rewena) suitable for organic growing systems were tested. External and internal fruit quality was assessed through standard parameters (fruit weight, firmness, soluble solids, malic acid) and sensorial quality by panel tests (fruit size, shape and colour; hardness, texture, juiciness, sweet/ac...

The nutritional value of fruit has been widely studied and is demanded by consumers, especially for protection against cardiovascular disorder, cancer and other diseases, as well as for general health benefits. These benefits can also be ascribed to the total antioxidant capacity (TAC) of fruit. Fruit nutritional quality can be described by a standard quality parameter and the analyses of nutri...

Foraging animals must often decide among resources which vary in quality and quantity. Nectar is a resource that exists along a continuum of quality in terms of sugar concentration and is the primary energy source for bees. Alternative sugar sources exist, including fruit juice, which generally has lower energetic value than nectar. We observed many honeybees (Apis mellifera scutellata) foragin...

Heterogeneity in fruit quality constitutes a major constraint in agri-food chains. In this paper the sources of the heterogeneity in pineapple in the field were studied in four experiments in commercial pineapple fields. The aims were to determine (a) whether differences in pineapple fruit quality among individual fruits are associated with differences in vigor of the individual plants within t...

The relationships between the fruit features of Juniperus communis and the presence of fruit pests were studied in Sierra Nevada, SE Spain. The abundance of two insect species a pulp-sucking scale and a seed-predator wasp was surveyed with respect both to fruit characteristics and to viability of seeds contained therein. Seed-predator pressure was not significantly related to any fruit characte...
