Volume 32, Issue 2 , May and June 2018, , Pages 299-312

https://doi.org/10.22067/jsw.v32i2.66097

Abstract
  Introduction: Global warming is strongly linked to the increase in greenhouse gas emissions to the atmosphere. One of the most efficient ways to reduce the amount of atmospheric CO2 is to produce a lot of biomass and convert the biomass into a biochar. Biochar is an organic carbon-rich solid that can ...  Read More

Volume 29, Issue 1 , March and April 2015, , Pages 176-187

https://doi.org/10.22067/jsw.v0i0.28483

Abstract
  Introduction: Use of unbalanced chemical fertilizers especially P, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). Bio-fertilizer is a preservative material consisting of one or several specific ...  Read More

Volume 24, Issue 1 , March and April 2010

https://doi.org/10.22067/jsw.v0i0.2920

Abstract
  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 ...  Read More

The roll of bacterial ACC deaminase enzyme on the alleviation of negative effects of salinity on canola growth

A.R. Akhgar; K. Khavazi

Volume 24, Issue 1 , March and April 2010

https://doi.org/10.22067/jsw.v0i0.2936

Abstract
  Abstract In this study a greenhouse experiment was conducted to evaluate the role of ACC deaminase enzyme on alleviation of salinity stress of canola plant. Canola plants were exposed to Pseudomonas fluorescens strain P12 which contains a rhizobacter capable of producing Pseudomonas fluorescens in comparison ...  Read More

Volume 23, Issue 1 , March and April 2009

https://doi.org/10.22067/jsw.v0i0.1551

Abstract
  Abstract Plant- growth promoting rhizobacteria enhance plant growth and yield directly and or indirectly. A factorial experiment was conducted in greenhouse to determine the efficacy of four strains of Fluorescent Pseudomonas on wheat yield and yield component under saline conditions. the experiment ...  Read More

Plasmid diversity of Sinorhizobium (Ensifer) bacteria

E. Karimi; A. Lakziyan; K. Khavazi; A. Asgharzadeh

Volume 22, Issue 2 , May and June 2008

https://doi.org/10.22067/jsw.v0i22.980

Abstract
  Abstract Genetic evidences have shown that the rhizobium bacteria nodulate the legume plants because of nod, sym and fix genes. Almost all members of rhizobaceae family harbor large plasmids, which are highly variable in number and size. Representative of nif, fix and nod genes have been located on ...  Read More
