we examined the effectiveness of intermittent warming (iw), hot water (hw), salicylic acid (sa), and calcium chloride (cacl2) on the postharvest life of pomegranate fruit cv. ‘shishe-kab’ and extending fruit shelf life during cold storage (3°c). fruit were subjected to cycles of 1 d at 17 ± 1°c every 6 d of storage at 3°c under iw conditions. pre-storage treatments were hw (50°c) for 3 min, sa ...

Preharvest herbicide treatment of undesirable and unmerchantable v getation was compared to postharvest felling. Ten years after the clearcut harvesting, the preharvest treatment had increased the number and proportion of desirable stems and decreased the number and proportion of undesirable sprouts in the dominant stand. Stands that developed after the preharvest herb•cide treatment are domina...

Certain nematicidal treatments for the control of root knot of tobacco in six field experiments in North Carolina were used to determine early, midseason, and postharvest densities of eggs and larvae of Meloidogyne spp., postharvest root-knot indices, and crop yield and value. Various statistical correlations showed that population densities determined 6-8 wk after transplanting were more indic...

sensitivity of tomato fruits to chilling injury limits its storage and marketability. this study investigated the effect of hot water treatment (hwt) on reducing the consequences of chilling injury (ci) with respect to quality attributes of tomatoes during storage. tomatoes were harvested at three ripening stages: mature green, pink, and red; dipped in hot water at 45°c for 15 min; and stored a...

The use of chemicals in postharvest technology of horticultural crops is highly restricted and it is necessary to introduce safe food preserving methods. Strawberry is very susceptible to postharvest losses and more than 50% of harvested fruit is lost in Iran. Effect of postharvest treatment with methyl jasmonate (at 0, 8, and 16 μmol L(-1)) on some quality attributes of Sabrosa strawberry frui...

Anthracnose of papaya fruit caused by the fungus Colletotrichum gloeosporioides is one of the most economically important postharvest diseases. Hot water immersion (HW) and calcium chloride (Ca) treatments have been used to control papaya postharvest diseases; however, the effect of the combination HW-Ca on the pathogen growth and the development of the disease in infected papaya fruit has been...

Purpose of review: The presence of arthropod pests in or on horticultural commodities has caused major disruptions in the storage, processing and shipment of these products. Management of these pests has posed a problem to humans for thousands of years. Current technology has led to the development of numerous means (chemical, mechanical or procedural) to control these pests. For the most part,...

Auxin plays essential roles in plant development. Gretchen Hagen 3 (GH3) genes belong to a major auxin response gene family and GH3 proteins conjugate a range of acylsubstrates to alter the levels of hormones. Currently, the role of GH3 genes in postharvest physiological regulation of ripening and softening processes in papaya fruit is unclear. In this study, we identified seven CpGH3 genes in ...

Postharvest heat treatments are being used for disinfestation and disinfection of an increasing variety of crops, including flowers, fruits and vegetables. This review focuses on the effects of heat on the commodity and its postharvest quality. The effects of a postharvest heat treatment on aspects of ripening and development of thermotolerance is discussed. Ethylene production, respiration, so...
