چکیده

Wet chemistry was used to produce copper oxide nanoparticles (CuO NPs). The results indicated that most were bacillus-shaped and relatively uniform in size (less than 30 nm). effect of synthesized CuO NPs on wheat (Triticum aestivum L.) germination growth parameters studied compared bulk Cu. showed no significant difference obtained rate among all treatments. Bulk Cu additions significantly affect the mean time. On contrary, germinability affected by additions. Seed vigor index calculated demonstrate superior treatment parameters, confirmed 0.1 mg L−1 could be successfully improve seed germination. Moreover, general average concentrations plant tissue 139 103 kg−1 dry weight for NPs, respectively, indicating dissolution behavior NPs. addition (0.1 L−1) promotes chlorophyll formation equal 0.5 addition. This means using as fertilizer reduce 80% traditional fertilizers. Nonetheless, both forms (NPs bulk) root substantially control. effective toxic dose (EC50) 0.37 0.94 L−1, respectively. approximately 2.5 times concentration is toxicity due lowered dissolution. Our study phytotoxicity a non-nanosized plant-induced changes under environmentally real conditions should considered when measuring near roots. implies nano-CuO micronutrient amendment has potential benefit rather soluble salt growth.

The wheat (Triticum aestivum L.) leaf proteome.

The wheat leaf proteome was mapped and partially characterized to function as a comparative template for future wheat research. In total, 404 proteins were visualized, and 277 of these were selected for analysis based on reproducibility and relative quantity. Using a combination of protein and expressed sequence tag database searching, 142 proteins were putatively identified with an identificat...

Effect of salinity on wheat (Triticum aestivum L.) grain yield, yield components and ion uptake

Crops growing in salt-affected soils may suffer from physiological drought stress, ion toxicity, and mineral deficiency. A pot study was conducted in 2004-2005 in the Aghala area (northern Iran) to study the effect of different salinity levels, i.e. ECe= 3 (control), 8, 12 and 16 dS m-1 on wheat grain, yield components and leaf ion uptake of four Iranian wheat genotypes, i.e. Kouhdasht, Atrak, ...

Aluminum Tolerance in Wheat (Triticum aestivum L.) (I. Uptake and Distribution of Aluminum in Root Apices).

We investigated the uptake and distribution of Al in root apices of near-isogenic wheat (Triticum aestivum L.) lines differing in Al tolerance at a single locus (Alt1: aluminum tolerance). Seedlings were grown in nutrient solution that contained 100 [mu]M Al, and the roots were subsequently stained with hematoxylin, a compound that binds Al in vitro to form a colored complex. Root apices of Al-...
