The respiration of slices of a variety of bulky storage tissues rises gra(lually three to fourfold within a (lay of cutting (7, 8, 9, 10). The respiration rate of freslh tissue cani be sharply raise(d ith 2,4 dinitrophenol, however, as (lemionstrate(I in chlicory and potato slices. Both the age-inducedI an(d DNPinducedl respiration incremzents are inhibite(d by imalonate. It has been sh]own tha...

citrus blast disease caused by pseudomonas spp is among the most injurious diseases of citrus. in the northern citrus growing provinces of iran. to determine the species and pathovars of pseudomonas strains associated with the disease in mazandaran province and in the neighboring areas in guilan and golestan provinces and as well to assess their phenotypic heterogeneity and virulence, symptomat...

In recent years, a number of studies have been miadle on the respiration of slices of potato tuber tissue (1, 6, 7, 8, 9, 11, 12, 13, 16, 17). \VXhen the slices or dlisks are freshly cut, they have a respiration rate sinmilar to that of the intact tuber. This tissue lhas been termed fresh tissue. \Vhen the fresh disks are kept by aerating them in distilled water or 10-4 Al CaSO4 at 00, the low ...

The aim of this work was to study the infrared (IR) drying of food products. In present article the effects of blanching, of air velocity and of different air temperatures on the drying time and on the rehydration ratio as a quality property are investigated. During research different food materials were used: apple, carrot and potato. In the article a simultaneous heat and mass transfer model ...

During the years 2007 and 2008, samples of winter jasmine (Jasminum nudiflorum) with symptoms of galls on shoots were collected from Shiraz, Fars province, Iran. Gram and oxidase negative, aerobic bacterium that produced fluorescent pigment on Kingۥs B medium was isolated from galls of infected trees. All isolates produced a hypersensitive reaction in tobacco. They were negative in arginine dih...

Suimiiary. The effect of temperature on the respiration rate of potato tuber slices has been analyzed in terms of the Arrhenius equation. Freshly cut disks, irrespective of thickness, show a linear response to increasing temperature up to 300 with an activation energy (E) of approximately 12.0 Kcal. Aged disks less than 1.0 mm thick also give a linear response with E similar to that of fresh di...
