Plant growth regulators (PGRs) are used to prevent reduction in wheat grain yield under limited moisture conditions. The effect of 3 PGRs including cycocel, salicylic acid and brassinoestroeid on yield and yield components of four wheat cultivars (Chamran, Shiroudi, Pishtaz and Sirvan) under well watered and water stress (withheld irrigation after flowering) was examined. The experiment was ca...
In order to study the effect of the superabsorbent polymer and manure fertilizer on the baking characteristics of wheat cultivars under different water deficit conditions, an experiment was carried out in a factorial layout based on a randomized complete block design in three replications at Agricultural Research Center, West-Azerbaijan (Saatlo station) during 2017-2018 growing seasons. The fac...
this research was investigated to study relationship among seed yield, seed yield components and morphological traits and their direct and indirect effects on seed yield of 100 safflower genotypes in two water environments (normal and drought stress) at research farm of isfahan university of technology during 2012. seed yield had positive correlation with number of head per plant, seed per head...
Due to low organic matter content in most of the cultivated soils of Iran and occurrence of drought stress in plants because of low precipitation, application of sewage sludge compost has been recommended for increasing soil organic matter content and improving soil fertility, increasing crop tolerance to water deficit and improving crop yield. So, in this study, the effects of soil moisture an...
Both local and large-scale processes affect the Amazon hydrologic cycle. We investigate the impact of deep soils on the atmosphere through local feedbacks. The Simple Biosphere model, version 3 (SiB3), is coupled to a single column model. Historically, land surface schemes parameterize soil moisture stress based on shallow soils and incorrectly capture seasonal cycles in the Amazon. Following o...
Carbon fiber reinforced plastic (CFRP) was used to adhesively reinforce Chinese fir (Cunninghamia lanceolata) wood specimens. This study examined the flexural static and creep performances of CFPR-reinforced wood composites that had been subjected to changes in moisture and stress levels. The major findings were as follows: 1) the cyclic creep was slightly lower for those specimens subjected to...
This paper presents the study of tensile, flexural & moisture absorption properties of composites made from areca fibers, maize powder filler particles & epoxy resin. The specimens are prepared using hand lay-up techniques as per ASTM standard for different weight fractions of fiber, filler & matrix material. The specimens were tested as per ASTM standards. Experimental results showed that tens...
Two rice varieties N22 (drought-tolerant) and Panidhan (drought-susceptible) were studied for the protein profiles under control, moisture stress and abscisic acid (ABA) treatments. Both qualitative and quantitative differences were observed. In control and ABA treatment, the number of polypeptides was more in N22, compared to Panidhan. However, a significant number of polypeptides were induced...
Recent warming has stimulated the productivity of boreal and Arctic vegetation by reducing temperature limitations. However, several studies have hypothesized that warming may have also increased moisture limitations because of intensified summer drought severity. Establishing the connections between warming and drought stress has been difficult because soil moisture observations are scarce. He...
