BACKGROUND Aflatoxins are toxic fungal metabolites enable to contaminate a wide range of natural substrates. This contamination can be host-specific for different plant species. In this study, the ability of a toxigenic Aspergillus parasiticus to produce various aflatoxins on major Iranian cereals was evaluated with special focus on plant susceptibility to toxin production at cultivar level. ...

using a wide range of techniques, including differential scanning calorimetry, x-ray diffraction, rapid visco analyser and fourier transform infera red spectroscopy, some physicochemical properties of the starch fraction of six iranian rice cultivars (tarom, tarome hashemi, neda, ramezani, fajr and kamfirouzi) [1]were studied and compared. dsc data showed that starch granules of different rice ...

Aphelenchoides besseyi is a seed-borne plant parasitic nematode and is widely distributed in most rice growing areas. Application of resistant cultivars requires the identification of resistance source, which can then be included in breeding programs to improve the local rice cultivars. Fourteen Iranian rice genotypes including improved and local varieties were evaluated for resistance to A. be...

ABSTRACT: A combined gas chromatography-mass spectrometry (GC-MS) with headspace solid-phase micro extraction (SPME) method has been employed for the analysis of the flavor volatiles of three different rice cultivar, including two modified Iranian rice cultivars and Hashemi rice cultivar during gelatinization. The proposed combination provided a powerful system for easy and rapid screening of a...

in order to study the effects of four concentrations (check, 5, 10 and 15%) of hull extracts on growth of 10 iranian rice cultivars, two experiments were conducted in completely randomized block design with factorial arrangement and three replications at two sites, laboratory and greenhouse. laboratory study showed that same rice hull extracts had stimulat effects and the others had inhibitory ...

An efficient system has been developed for the reproducible regeneration of plants from cell suspension-derived protoplasts of the two commercial Iranian Japonica rice cultivars Tarom and Khazer. Friable embryogenic calli were used for cell suspension initiation and protoplasts were isolated from both varieties. When embedded in agarose, protoplasts failed to divide. However, sustained division...
