We evaluated the yields of Oryza sativa L. 'Nipponbare' rice lines expressing a gene encoding an A20/AN1 domain stress-associated protein, AlSAP, from the halophyte grass Aeluropus littoralis under the control of different promoters. Three independent field trials were conducted, with drought imposed at the reproductive stage. In all trials, the two transgenic lines, RN5 and RN6, consistently o...
The effects of irrigation water salinity (12 dS m−), imposed at maximum tillering (35−40 days after sowing, DAS) or booting (50−60 DAS) or grain filling (75−85 DAS) stage of wheat, on growth and yield of the crop was demonstrated. The experiment comprised four treatments – I1: irrigation by fresh water (FW) at all three growth stages (control), I2: irrigation by saline water (SW) at maximum til...
Phenology provides important information for wheat growth management and the estimation of yield quality. The relative threshold method has been widely used to retrieve phenological metrics from remotely sensed data owing its simplicity. However, thresholds vary substantially among locations, hampering us effectively detecting spatial temporal variations in winter phenology. In this study, we d...
In order to evaluate the effect of trinexapac ethyl concentrations (0, 250 and 500 g/h) and traffic stress (traffic and non traffic) treatments on wheat grass physiological and morphological traits, an experiment was conducted on research farm of Isfahan University of Technology in 2011 - 2012 as factorial in completely randomized designs with three replications. The studied traits involved pla...
Flooded rice fields are an important source of the greenhouse gas CH(4). Possible carbon sources for CH(4) and CO(2) production in rice fields are soil organic matter (SOM), root organic carbon (ROC) and rice straw (RS), but partitioning of the flux between the different carbon sources is difficult. We conducted greenhouse experiments using soil microcosms planted with rice. The soil was amende...
Arsenic (As) accumulation in rice owing to uptake from the soil is a critical human health issue. Here, we studied the chemical properties of As-treated soils, growth inhibition patterns of As-stressed rice plants, changes in the As content of soil and soil solutions, and the relationship between As accumulation and As transfer factor from the soil to the rice organs. Rice plants were cultivate...
