Certain microorganisms in soil have phosphate solubilizing ability. Phosphorus has an important role in plant nutrition and N2 fixation in legumes. The interactive effect of three phosphate solubilizing bacteria (PSB) and Bradyrhizobium japonicum on yield and N, P, K uptake and nodulation of soybean root (Glycin max L. CV. Harcor) was studied under greenhouse conditions. In greenhouse experimen...

Lead (300 mum) and cadmium (18 mum) inhibit pod fresh weight in soybeans (Glycine max L.) by 35%. Eighteen micromolar cadmium caused a 30% decline in nitrogenase activity by day 52 (the day on which maximum activity was measured) and a 71% inhibition by day 59. The heavy metals depressed photosynthetic rates; when photosynthesis was depressed by 60%, as measured on the day of peak photosynthesi...

Cadmium (Cd) pollution is a major environmental and human health threat. Therefore there is a need for cost-effective remediation procedures. Chelators such as humic acid have shown positive effects in enhancing resistance to various stresses. The objective of this research was to investigate the use of humic acids at cadmium-contaminated soil on growth and soluble sugar concentration of aloe v...

A laboratory research carried out to evaluate the effect of drought stress on germination characteristics in two 'Indian' and 'Isfahanian' populations of Fenugreek. This experiment performed in a factorial experiment based on a completely randomized design with three replicates. Four levels of drought stress applied by using polyethylene glycol 6000. Percentage of germination, germination rate,...

In the following study, dose dependent effects on growth and oxidative stress induced by β-radiation were examined to gain better insights in the mode of action of β-radiation induced stress in plant species. Radiostrontium (⁹⁰Sr) was used to test for β-radiation induced responses in the freshwater macrophyte Lemna minor. The accumulation pattern of 90Sr was examined for L. minor root and frond...

Hairy root cultures of Nicotiana tabacum were set up by excised root tips with Agrobacterium rhizogenes. The successful transformation was confirmed by analyzing rolC and virC genes using polymerase chain reaction (PCR). Hairy root cultures were employed to study the formation of pyridine alkaloids, mainly nicotine. The transformed cultures were incubated with potential elicitors, such as methy...

    Seed germination has an important role in the life cycle of plants and critical stages of the growth cycle, establishment and final yield. Seed germination is the most critical stage of seedling establishment which ultimately determines the successful production of the product. Salinity is one of the environmental factors reducing crop production in the world. Saline soils or irrigation the...

The aim of this study was to evaluate effect of foliar application of titanium dioxide nanoparticles on quantitative traits and essential oil, thymol and carvacrol percent of thyme under different levels of water stress. Factorial experiment was used based on a completely randomized design with four replications. Factors included water stress (50, 70 and 90% of field capacity) and titanium diox...
