Effect of Copper Contamination on Soil Biochemical Activity and Performance of Rice (Oryza sativa L.)
Copper (Cu) is an essential element for regular functioning of organisms. It plays significant role in number of physiological processes like photosynthetic and respiratory electron transport chains, N fixation, protein metabolism, cell wall metabolism, anti oxidant activity, fatty acid metabolism and harmone perception. However, excessive amounts of Cu in the root zone inhibit growth, chlorosi...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
In vitro screening for salt tolerance in Rice ( Oryza sativa )
An experiment was conducted to study the performance of rice genotypes for salt tolerance under in vitro condition. Seven genotypes include salt tolerant (Pokkali, CSR 10, TRY 1 and TRY2), moderately tolerant to salt (White Ponni and BPT 5204) and susceptible (IR 29) were used for this study through embryo culture technique. Callus was initiated in MS medium + 2 mgl 2,4D + 0.5 mgl Kin and diffe...

15 صفحه اولEffect of CO2 enrichment and elevated temperature on methane emissions from rice, Oryza sativa
Methane emissions from rice grown within Temperature Gradient Greenhouse Tunnels under doubled CO2 concentrations were 10±45 times less than emissions from control plants grown under ambient CO2. For two cultivars of rice (cvs. Lemont and IR-72), methane emissions increased with a temperature increase of 2°, from outdoor ambient temperatures to the ®rst cell of the ambient CO2 tunnel (ambient t...
