Drought stress is one of the most important factors affecting plant growth. Plant growth under drought stress may be enhanced by the application of microbial inoculation including plant growth promoting rhizobacteria. This research was conducted as a factorial experiment in a completely randomized design. The first factor included the bio-fertilizer (A. vinelandii (A)), P. agglomerans+ P. ...

drought is an important abiotic stress limiting plant performance. generation of reactive oxygen species (ros) is enhanced under stresses. two greenhouse experiments were conducted to evaluate the effect of phytohormones on the changes of antioxidant enzymes and carotenoids in petals of pot marigold (calendula officinalis l.) under drought stress. results showed that the activities of superoxid...

A high-resolution, numerical study of an idealized western boundary current flow over variable topography is presented, with application to the East Australian Current (EAC). The results indicate that alongshelf topographic variations off Australia’s east coast cause the EAC to accelerate over the narrowing continental shelf near Cape Byron. This acceleration is sufficient to hinder the geostro...

in order to investigate the effect of sodium nitroprusside (snp) application on yield and yield components of kidney bean under water deficit stress, a field experiment was conducted in split-factorial based on randomized complete block design with three replications in hamedan, in 2012. water deficit stress at four levels including vegetative stress, reproductive stress vegetative+reproductive...
