in order to investigate the influence of bio- and chemical fertilizers on growth parameters and essential oil of fennel (foeniculum vulgare miller.), an experiment based on randomized complete blocks design with five treatments and three replications was carried out. arbuscular mycorrhizal fungi (strain sebacina vermifera) and phosphate dissolving bacteria (genera peseudomonas) were applied as ...

abstract in order to study the effect of various densities of wild mustard (sinapis arvensis l.) on growth indices of canola (brassica napus l.) in climate of molathani, ahvaz, an experiment was conducted in the experimental field of ramin agricultural and natural resources university, in 2006-2007. the split-plot set of treatments was arranged within randomized complete block design with four ...

the effect of various host plants including chickpea (varieties arman, hashem, azad and binivich), common bean (variety khomein), white kidney bean (variety dehghan), red kidney bean (variety goli), cowpea (variety mashhad), and tomato (variety meshkin) on the reproductive performance and growth indices of the cotton bollworm, helicoverpa armigera (hübner) was determined under laboratory condit...

this study investigated the variation between two sugar beet (beta vulgaris l.) cultivars with respect to growth parameters and photosynthetic rates of individual attached leaves during salinization. sugar beet plants grown in sand culture were gradually exposed to different levels of salinity (0, 50, 150 , 250, and 350 mm, nacl+cacl2 in 5:1 ratio). salt concentrations significantly decreased a...

The C1 promoter expressing the AC1 gene, and V1 promoter expressing the AV1 gene are located in opposite orientations in the large intergenic region of the Cotton leaf curl Burewala virus (CLCuBuV) genome. Agro-infiltration was used to transiently express putative promoter constructs in Nicotiana tabacum and Gossypium hirsutum leaves, which was monitored by a GUS reporter gene, and revealed tha...

The threat of arsenic (As) pollution has become serious and leading to opt low-cost microbial remediation strategies.Some bacteria have the ability resist As. A group rhizosphere absorb arsenic. So these may be a good candidate for bioremediation from contaminated environment. Our present study identifying suitable rhizobacterial strains led isolation As-tolerant pollutedrhizospheric soils lent...

Platycodon grandiflorus is a medical, ornamental, and edible traditional Chinese medicine whose seed germination plant growth are frequently restricted by dormancy stresses. In this study, we investigated how chitosan soaking affected germination, growth, photosynthesis, resistance, yield, quality of P. grandiflorus. The results indicated that had preferable enhancing effect on grandiflorus, wh...

Plant growth stimulating and antagonistic properties of 7 bacterial isolates beneficial Enterobacter spp. (EPR1- EPR7) screened from the rhizospheric soil Phaseolus vulgaris plants growing in Garhwal Himalaya, Uttarakhand, India was studied against borne phytopathogen Sclerotinia sclerotiorum causes root rots various crops. Among isolates, EPR4 showed 64.8% reduction colony fungal pathogen dual...

Inducible gene expression is a powerful tool to study and engineer genes whose overexpression could be detrimental for the host organisms. However, only limited systems have been adopted in plant biotechnology. We have developed an osmotically inducible system using three components of plant origin, RD29a (Responsive to Dehydration 29A) promoter, CBF3 (C-repeat Binding Factor 3) transcription f...

abstract the objective of this study was to assess the effects of few arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria on the growth and yield indices of two wheat varieties in a saline soil (ec=10/1 dsm-1). a factorial experiment with completely randomized design with four replications was conducted to investigate the effects of three levels of fungal inoculation (non inoc...
