The absorption behavior of technetium (Tc) and rhenium (Re) through plant roots was studied using nutrient solution culture. Radish samples, grown in culture solutions for 20-30 days in a greenhouse, were transferred into plastic vessels containing nutrient solutions contaminated with multitracer solutions including Tc and Re. The plant samples were grown individually for 1-7 days under laborat...

This study was carried out to determine the effects of putrescine(Put) and humic acid (HA) foliar applications on growth, yield and chemical composition of Egyptian cotton (Gossypium barbadense L. cv. Giza 90)plants grown under saline soil condition. A soil mixture of, clay: sand (1:1), was used as a plant growing media. Three different doses of putrescine (0, 1 and 2 ppm) and humic acid (0, 1 ...

Plant residues of broccoli, melon, and tomato with or without addition of chicken manure were used as biofumigants in two pot experiments with Meloidogyne incognita-infested soils. The efficacy of these biofumigants in controlling M. incognita infestation in susceptible tomato bio-assay plants was studied at soil temperatures of 20 masculine, 25 masculine, and 30 masculineC. None of the plant r...

To improve the efficiency of chromium (Cr) phytoextraction by Leersia hexandra Swartz, effects mowing on Cr accumulation in L. were investigated using hydroponic experiments. Mowing heights (0, 5, and 10 cm), interval (30, 60, 90 120 days), frequencies (1, 2, 3 times) optimized. at cm above roots significantly increased shoot biomass (32.9 g/pot). The days achieved highest (62.8 with thrice (67...

A pot culture experiment was conducted to study the effect of soil amendment with different forms groundnut waste on spore population and root infection indigenous Arbuscular Mycorrhizal fungal species i.e. Glomus mosseae under polyhouse conditions. Two angiospermic plant viz. sorghum sesame were also examined for mycorrhization potential in study. Observations made percent colonization, densit...

This study aimed to investigate the effect of nano-Ca fertilizer on nitrogen uptake, use efficiency and determine best calcium form dose for mango. A pot experiment was conducted using two year old mango seedlings (cv. Zebda). The pots were filled with sandy soil (8 kg per pot) one seedling transplanted into each pot. Four treatments including nano-Ca, convention Ca, application foliar have bee...

We investigate the electronic characteristics and the absorption spectra of poly(3-octylthiophene), POT, films grown by electrochemical methods onto Au substrates. We discuss the results considering the morphological factor. POT films thickness can be controlled by current density in the electropolymerization process. The film roughness depends on the thickness, being about 12% of film thicknes...
