Climatic stresses limit plant growth and productivity. In the past decade, tree improvement
programs were mainly focused on yield but it is obvious that enhanced stress resistance is …

As one of the most important limiting factors of grassland productivity, drought is predicted to
increase in intensity and frequency. Greenhouse studies suggest that arbuscular …

Drought is one of the major abiotic stresses accepted as the main constraint for loss of the
crop yield worldwide. Further, problems are created by nutrient limitations particularly low …

The objective of this study was to investigate the effects of drought stress on the activity of
antioxidant enzymes and osmotic adjustment substance content in the tillering period of …

The rhizosphere is colonized by a mass of microbes, including bacteria capable of
promoting plant growth that carry out complex interactions. Here, by using a sterile …

Drought stress is one of the major limiting factors for worldwide crop production. In this
regard, plant growth promoting rhizobacteria (PGPR) have been reported to play significant …

Background For scavenging reactive oxygen species, plant possess effective system that
protect them from destructive oxidative reaction. Parts of this system as osmoprotectants and …

Drought represents a major constraint for agricultural productivity and food security
worldwide. Plant growth promoting actinobacteria have attracted the attention as a …

The phyto-impact of tungstate is not frequently studied like other heavy metals especially in
the sight of continuous accumulation of tungstate in the agriculture soils and water. Thus, the …

Water stress is the main factor responsible for decreased productivity, which affects the
growth and development of crops. Plants respond to stress by accumulating compatible …
