harvesting of sour cherries is very difficult task which is done either by machine or hand. in order to facilitate fruits harvesting ethephone with different densities is used. in this research work iranian produced ethephone with density of 1.18 g/cm3 and england produced ethephone with density of 1.45 g/cm3 was utilized with different concentration (0, 150, 225 and 300) in a 2×4 factorial exp...

High quality fruits are increasingly demanded along with the need to ensure this attribute to consumers. Thus, this study was aimed at characterizing a melting (‘Elegant Lady’) and a non-melting flesh (‘Carson’) peach (Prunus persica (L.) Batsch) varieties by considering both their bioactive compound contribution and their sensory quality in ripe fruit at harvest and after a prolonged period of...

Nondestructive firmness measurement is critical to assuring postharvest quality and marketability of apples. In this research, two in-house developed sensors (bioyield and spectral scattering) and two commercial sensors (acoustic and visible and shortwave nearinfrared (Vis-SWNIR) spectroscopy), were evaluated for assessing the firmness of apples. Spectral scattering measurements were taken from...

Genotypic variation in composition and antioxidant activity was evaluated using 25 cultivars, 5 each of white-flesh nectarines, yellow-flesh nectarines, white-flesh peaches, yellow-flesh peaches, and plums, at the ripe (ready-to-eat) stage. The ranges of total ascorbic acid (vitamin C) (in mg/100 g of fresh weight) were 5-14 (white-flesh nectarines), 6-8 (yellow-flesh nectarines), 6-9 (white-fl...

The time is ripe to start a science of identities for their own sake, without paying lip-service to high-brow mathematics. Although putting combinatorial, (abstract-) algebraic or analytic flesh and blood on identities did lead and will lead to considerable insight as well as new identities, there is also much to be gained in forgetting advanced mathematics, and starting a new sub-discipline of...

introduction: there are two types of japanese persimmon (diospyros kaki thunb.), astringent and non-astringent, based on the degree of astringent taste at maturity state. fruits of either type are strongly astringent when small and immature, but non-astringent type loses its astringency during development on the tree, still with firm flesh. however, the astringent type keeps its astringency and...

Winter pruning has been a common practice in peach. Twig topping associated with it, but this used at the same intensity, regardless of cultivar. Therefore, study aimed evaluating productive behavior and quality ‘Maciel’ peach grafted on ‘Capdeboscq’ ‘Okinawa’ (P. persica) as rootstocks, when they were submitted to different twig intensities winter pruning. The following three evaluated: short ...
