Antioxidative efficiency of Triticum aestivum L. exposed to chromium stress.
Wheat (Triticum aestivum L. cv Sonalika) seedlings were grown in presence of K2Cr2O7 (10, 50 and 100 ppm) for 7 days and growth, total chlorophyll, activities of antioxidative enzymes like superoxide dismutase (SOD; EC 1.15.1.1), catalase (CAT; EC 1.11.1.6) and guaiacol peroxidase (POX; EC 1.11.1.7) and lipid peroxidation were determined in root and shoot tissues. Growth of the seedlings was si...
متن کاملAllelopathic Effects of Sisymbrium irio L. and Descurainia sophia (L.) Schur on the Germination of Wheat (Triticum aestivum L.)
An experiment was conducted under controlled conditions to study the effect of water extract of leaves, shoots and roots of either Sisymbrium irio L. =SISIR and/or Descurainia sophia (L.) Schur =DESSO on the germination and primary growth of wheat. A split-split plot experiment in CRD with three replications was used. The main plots were the type of weed: i.e. SISIR and DESSO and the sub-plots ...
متن کاملEffects of Gamma Radiation on Germination and Physiological Aspects of Wheat (triticum Aestivum L.) Seedlings
This investigation was carried out to determine the effects of gamma radiation on germination and physiological characteristics of wheat seedlings. Two wheat genotypes (Roshan and T-65-58-8) were irradiated with 100, 200, 300 and 400 Gy. The results showed that MGT (Mean Germination Time), root and shoot length, and seedling dry weight decreased with increasing radiation doses but final germina...
متن کاملEffect 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...
متن کاملAllelopathic Effects of Aqueous Extracts of Sunflower on Wheat (triticum Aestivum L.) and Maize (zea Mays L.)
Sunflower is a potent allelopathic plant which possesses important allelochemicals with known allelopathic activity on other plants. In this study, allelopathic effects of fresh aqueous extracts (FAE) and air dried aqueous extracts (DAE) of root, shoot and leaves of sunflower (Halianthus annuus L.) were investigated on germination and seedling growth of wheat (Triticum aestivum L.) and maize (Z...
