because of the harmful effects of chemicals on human health and environment, use of these compounds in postharvest technology of agricultural crops is recently restricted and it is necessary to find safe compounds for use in postharvest technology of fruits and vegetables. in this study, effects of salicylic acid and aloe vera gel on quality attributes and postharvest life of table grape(cv. gi...

ALTERNATIVES TO ANTIOXIDANTS In recent years increasing interest in health and the environment has stimulated studies of alternatives to the usual procedures for controlling pests and diseases. The fact that antioxidants are applied after harvest on fruit generally consumed fresh subjects them to close scrutiny. Therefore it is imperative to find dependable alternatives for scald control in app...

ABSTRACT Eight strains of Metschnikowia pulcherrima isolated over a 4-year period from an unmanaged orchard and selected for their biocontrol activity against blue mold (caused by Penicillium expansum) of apples were characterized phenotypically, genetically, and for their biocontrol potential against blue mold on apples. All strains grew well and only differed slightly in their growth in nutri...

3. DECAY PREDICTION. Unfortunately, decay prediction models for stone fruit have not been developed yet. A possible method of disease prediction might consist of prior to commercial harvest placing fruit of more advanced maturity into a plastic bag with wet paper to induce decay development. If decay develops rapidly, this may suggest that some lots of fruit receive additional preharvest fungic...

A. R. Collins explained that damage to DNA was the originating event in the process of carcinogenesis. “The damage can be caused by environmental or endogenous (produced within the body) processes, and oxidative damage caused by reactive oxygen molecules released during cellular respiration is thought to make a significant contribution.

'Bing' cherries, Prunus avium L., were obtained from an organic orchard and a conventional commercial orchard. The two groups were examined separately in replicated tests infested with each fruit initially infested with a first-instar codling moth, Cydia pomonella (L.). To simulate commercial postharvest holding conditions, the treatments were 0 (control), 1, 2, 4, 7, 10, and 14 d cold storage ...

The genus Trichoderma comprises a great number of fungal strains that act as biological control agents, the antagonistic properties of which are based on the activation of multiple mechanisms. Trichoderma strains exert biocontrol against fungal phytopathogens either indirectly, by competing for nutrients and space, modifying the environmental conditions, or promoting plant growth and plant defe...

in vitro assessment of the antifungal activities was evaluated in the present study for both aqueous and ethanol extracts prepared from leaves of avicennia marina and rhizophora mucronata . leaves of mangrove species were collected from qeshm and syrik of south-east coast of iran, mangrove forest respectively. antimicrobial tests were carried out through disk diffusion method. minimum fungicida...

Mango, a tropical fruit of great economic importance, is generally harvested green and then commercialised after a period of storage. Unfortunately, the final quality of mango batches is highly heterogeneous, in fruit size as well as in gustatory quality and postharvest behaviour. A large amount of knowledge has been gathered on the effects of the maturity stage at harvest and postharvest condi...
