the main postharvest problems of persimmon in iran are severe softening and disease incidence on the fruits during storage. therefore, delay in softening and/or control of diseases result in the storage life extension of persimmon fruit. the strategy of induced disease resistance in plants by biotic and abiotic treatments is an attractive method for controlling diseases. salicylic acid (sa) is ...

The origin of root softening during cassava retting was investigated in a natural retting and in a sterile fermentation. Softening only occurred in the natural retting. Although high activities of endogenous pectin methyl esterase were found in cassava extracts from both fermentations, the depolymerizing enzymes polygalacturonase, active at low pH, and pectate lyase were only found in the non-s...

This study compares the capability of two different mathematical forms of the so-called softening variable to describe strain-induced stress softening observed within cyclic uniaxial tension of the human thoracic aorta. Specifically, the softening variable, which serves as the stress reduction factor, was considered to be tangent hyperbolic-based and error function-based. The mechanical respons...

Papaya (Carica papaya L.) is a climacteric fleshy fruit that undergoes dramatic changes during ripening, most noticeably a severe pulp softening. However, little is known regarding the genetics of the cell wall metabolism in papayas. The present work describes the identification and characterization of genes related to pulp softening. We used gene expression profiling to analyze the correlation...

One of the principal changes that takes place in apples as they ripen on the tree and in storage is the softening of the flesh of the fruit. In recent years many studies have been made on the ripening and storage of apples (iO),^ and in these the softening of the fruit has been given major consideration. In general, it has been found that there is a gradual, though somewhat irregular, softening...

Shear instabilities in the form of shear bands are often observed during high speed, plastic deformations of metals. According to one theory, their formation is attributed to eeective strain-softening response, which results, at high strain rates, as the net outcome of the innuence of thermal softening on the, normally, strain-hardening response of metals. In order to test the core instability ...
