The transcription patterns of [FeFe]-hydrogenase genes (hydA), which encode the enzymes responsible for H2 production, were investigated during rice straw decomposition in paddy soil using molecular biological techniques. Paddy soil amended with and without rice straw was incubated under anoxic conditions. RNA was extracted from the soil, and three clone libraries of hydA were constructed using...

The efficiency of brown rice and germinated brown rice as a substrate for probiotic food was investigated. Lactobacillus isolated from goat milk was used for fermenting the rice medium. Brown rice (BR) obtained by dehulling the paddy, was germinated for 48 h. The dried powders of BR and Germinated BR (GBR) were compared for the growth of Lactobacillus sp. and nutritive evaluation such as carboh...

The aim of the research was analysis of rural women’s role in paddy cultivation practices in Tonekabon Township. Research population was consisted of paddy farmers women in Tonekabon Township (N=14539), whose 130 ones were selected using Cochran’s formula. Data were gathered by cluster random sampling method. The instrument for data collection was a questionnaire which its validity was confirme...

in order to study the gene actions and heritability of the physical and chemical characteristics associated with appearance and cooking quality of rice grain, generation mean analysis was performed using a cross between two iranian rice cultivars, deylamani and sepidroud, having different quality characters. seeds of the parental lines and f1, f2, bc1 and bc2 generations were grown in randomize...
