چکیده مقاله:

A greenhouse experiment was conducted in 2013 in Research Lab of Karaj Islamic Azad University to determine the yield and activity of chemical markers as the response to different concentrations of Cadmium (Cd) (0, 5, 10 and 20 mg of Cd/kg of soil) in wheat cultivars (Karaj 1 and Karaj 2). Treatments were tested in a factorial experiment with four replications in 7.5 kg plastic pots. The response of seed yield and other parameters to Cd was negative, but the rate of Di-Tyrosine (Di-Ty) was increased. In comparison of cultivars, Karaj 1 had higher production and lower rates of Di-Ty at high concentrations of Cd than Karaj 2. There was a significant increase of Di-Ty in the leaf tissue due to Cd increase. The effects of Cd were high on measured characters in control treatments. This reaction was due to increase of Di-Ty by heavy metals in cultivars. Finally cultivars need to have high tolerance to Cd for optimum production of seed yield in this study at high concentrations of cadmium, but high yield in Karaj 1 was related to low rates of Di-Ty.

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 Cadmium on Seed Germination and Seedling Growth of Four Wheat (triticum Aestivum L.) Cultivars

Cadmium (Cd) is extremely toxic metal and reduces plant growth. Therefore, study was conducted to evaluate the effect of various Cd levels 0, 5, 20, 50 and 80 mg L on seed germination and seedling growth of four wheat cultivars (Sehar-06, Fareed-06, Inqlab-91, Chakwal-50). Cadmium showed toxicity at 5 mg L in case of root and shoot growth whereas 20 mg L in case of seed germination and germinat...
