The ability of two varieties (hard and soft) of almond peels, as inexpensive sorbents for the removal of bezanyl red (acid dye) from synthetic aqueous solutions has been studied. After their characterization by different techniques, (elemental analysis, biochemical analysis, IR spectroscopy, thermogravimetric analysis, scanning electron microscopy and mercury porosimetry), the dye sorption kine...

During 2015, vines receiving season-long drip irrigation delivered into the lower root zone via hard plastic tubes yielded 70 % of commercial production while receiving only 15% of the water as the vines receiving full commercial rates of surface drip irrigation. Vines receiving direct root-zone (DRZ) irrigation at rates reduced to 60, 30, and 15% of commercial drip irrigation (DI) produced ind...

Grapevine leafroll disease (GLD) is caused by a complex of vector-borne virus species in the family Closteroviridae. GLD is present in all grape-growing regions of the world, primarily affecting wine grape varieties. The disease has emerged in the last two decades as one of the major factors affecting grape fruit quality, leading to research efforts aimed at reducing its economic impact. Most r...

The fungus Gnomonia comari, causal agent of strawberry leaf blotch, was inoculated at the crown of young axenized strawberry plants growing in sterilized sand. Only the roots were colonized, and the infection was symptomless. When the fungus colonized the roots in the presence of the root lesion nematode Pratylenchus penetrans, the plants were extremely stunted and their root system was necroti...

background and objectives: septoria tritici blotch (stb), caused by mycosphaerella graminicola (anamorph s. tritici) is currently the most serious disease of wheat worldwide. this study was established to determine the function of resistant genes of m. graminicola to find out the number of genes corresponding in resistant reaction and also to estimate the genetic parameters of resistance. mater...

• The trial was carried out at 2 sites. The vines in both sites were trained to a 2-wire vertical trellis. The only difference was: Site 1 was thinned with a Gregoire G65 harvester, and used three pairs of bow rods to thin the lower third of the canopy. Site 2 used a URM Vinestar harvester, and used four pairs of bow rods to thin the lower half of the canopy. The reason only a portion of the ca...

A study was designed to compare the color components and color stability of red wine from Noble (Vitis rotundifolia) and Cabernet Sauvignon (Vitis vinifera) at four pH levels (2.8, 3.0, 3.3, 3.8). Noble browned to a much greater extent and lost more color after 10 and 16 months than did Cabernet, and Noble did not increase in chemical age (level of polymeric anthocyanin) to nearly the extent th...
