to evaluate the nutritive value in some lignocellulosic materials, 3 sets of experiments were conducted on aspen, and grape woods. to enhance the digestibility, the woods were treated with 5% naoh. throughout the first trial, chemical composition and digestibility coefficients of dry matter, organic matter and ndf of experimental feeds, ph of rumen, as well as palatability were evaluated while ...

Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...

Eutypa lata is a vascular pathogen of woody plants. In the present study we (i) determined which component(s) of the cell wall polymers were degraded in naturally infected grapevines and in artificially inoculated grape wood blocks; (ii) compared the pattern of wood decay in the tolerant grape cv. Merlot versus the susceptible cv. Cabernet Sauvignon; and (iii) identified secondary metabolites a...

Seedling regeneration and morphology of Oregon grape (Berberis nervosa Pursh) and salal (Gaultheria shallon Pursh) were studied in thinned and unthinned Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the central Coast Range, Oregon. Aboveand below-ground growth of both species were significantly and negatively correlated with stand density. Oregon grape appears to have less potent...

oral allergy syndrome (oas) is occasionally observed following consumption  of raw fruits  in  allergic adults. since this  phenomenon  was  commonly  reported  in  khorasan province of iran; we intended to check if common  diagnostic tests could be applied for differential diagnosis of oas to grapes. ige reactivity of 84 patients with oas to grape and 34 patients with oas to other fruits were ...

Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...

the entomopathogenic fungus metarhizium anisopliae (metschnikoff) sorokin, causal agent of green muscardine of insects, is an important fungus in biological control of pests. no reports exist on the impact of this fungus on microcerotermes diversus silvestri (iso.: termitidae) in the world. the present research evaluated efficacy of strain demi001, from saravan, iran, against m. diversus. the t...

A 3-yr field study was conducted at commercial grape farms to evaluate cutting wild grapevines as a cultural control strategy for grape berry moth, Paralobesia viteana (Clemens). At each farm, wild grapevines were cut in the woods adjacent to one vineyard for control of P. viteana, whereas the comparison vineyard received no such cutting. Both vineyards received a standard broad-spectrum insect...
