Phytohormones are chemical messengers produced in one part of plant and translocated to the other parts, where they play critical roles in regulating plant responses to stress at extremely low concentration. Phytohormones are natural products and they called plant growth regulators, when they are synthesized chemically. Plants are usually subjected to(More)
IAA produced by bacteria of the genus Azospirillum spp. can promote plant growth by stimulating root formation. Native Azospirillum spp., isolated from Irannian soils had been evaluated this ability in both qualitative and quantitative methods and registered the effects of superior ones on morphological, physiological and root growth of wheat. The roots of(More)
The aim of present study is evaluation of the effect of four rates of superabsorbent polymer (0, 75, 150 and 225 kg ha(-1)) and three irrigation intervals (6, 8 and 10 days) on growth and yield of soybean (cult. L11) under field conditions. The results of this study showed that there was a significant effect among irrigation intervals on seed yield, Total(More)
Phytohormones, such as auxin and cytokinin, are known to be involved in the regulation of plant responses to salinity stress and counteract the adverse effect of stress conditions. This work investigated the effects of the exogenous spraying of indole-3-acetic acid (IAA) and kinetin (KIN) during the reproductive phase on grain yield by examining the(More)
The de-inking process produces a waste by-product, called de-inking paper sludge (DS), that contains paper fibers, clay particles and inks and high carbon (C) concentrations combined with low nitrogen (N) and phosphorus (P) concentrations. The use of high rates of DS to increase the soil organic matter thus requires provision of high rates of N and P for(More)
