Overproduction of Some Plant Growth Promoters by Rhizospheric Microorganisms on Natural Medium

Some effects of plant growth-regulating substances on microorganisms.

Effect of rhizospheric microorganisms inoculum on sweet pep - per quality

The effect of the interaction among rhizospheric microorganisms and plant roots on plant physiology has been largely investigated and it is well known that they can improve plant nutrition, water efficiency, bioprotection against pathogens, and crop productivity. Several inocula composed of arbuscular mycorrhizal fungi and Plant Growth Promoting Rhizobacteria (PGPR) are commercially available. ...

Inhibitory Effects of Low Temperatures on the Rhizospheric Microorganisms and Apple Rootstock Growth

The contribution of nitrogen (N) supply is an essential source for the growth of apple trees from budding to fruiting. In new apple-producing regions of north China, such as the Shenyang area, air temperature rises rapidly, while in contrast, soil temperature rises very slowly. In such weather conditions, the amount of nitrogen absorbed by the roots is not sufficient for the growth and developm...

Impact of silver ions and silver nanoparticles on the plant growth and soil microorganisms

There is a growing consumer market for products that proclaim to decrease microorganism counts to prevent infections. Most of these products are loaded with silver in its ionic or nanoparticle form. Through use or during production, these particles can find their way into the soil and cause an impact in microbial and plant communities. This study aims to evaluate the impact of silver based part...

Complementarity among plant growth promoting traits in rhizospheric bacterial communities promotes plant growth

An assessment of roles of rhizospheric microbial diversity in plant growth is helpful in understanding plant-microbe interactions. Using random combinations of rhizospheric bacterial species at different richness levels, we analysed the contribution of species richness, compositions, interactions and identity on soil microbial respiration and plant biomass. We showed that bacterial inoculation ...
