Over-grazing may induce changes in the dynamics of plant residue carbon and soil organic carbon (SOC). The objective of this study was to evaluate the litter quality of three dominant pasture species, and the relationship between litter quality and C dynamics under different range managements in native rangelands of SabzKou. Aboveground litters from three dominant species including, Agropyron i...
This study aimed to investigate plant species diversity in the ecological species group in relation to the environmental factors. A study area of 216 ha in the southeast of Baghmalek on which seventy 20×20 m plots were established according to the random-systematic method was selected. Soil properties and physiographic factors were recorded at each plot. Herbaceous species composition was recor...
Multiple cropping (i.e. intercropping or mixed cropping) plays an important role in agriculture because of the effective utilization of resources, significantly enhancing crop productivity compared with that of monocultured crops. The study was planed to assess the effect of various concentrations (00, 30, 60, 90 kg ha(-1)) of phosphorous on the biochemical composition of grains of Hordeum vulg...
Zestaw 478 linii jęczmienia (Hordeum vulgare L.) był badany pod kątem odporności na mączniaka prawdziwego. Badane linie wyprowadzono z odmian miejscowych jarego pochodzących głównie Basenu Morza Śródziemnego. W badaniach wykorzystano trzy izolaty Blumeria graminis o znanym profilu wirulencji. Ocenę wykonano siewkach w warunkach kontrolowanych. Badanie pozwoliło wyselekcjonować 111 odpornych jęc...
The phylogenetic position of hexaploid Elymus repens within the tribe Triticeae (Poaceae) was examined using cloned sequences from the low-copy nuclear genes encoding phosphoenolpyruvate carboxylase (pepC) and beta-amylase. A previous analysis of E. repens using data from the nuclear granule-bound starch synthase I (GBSSI) gene had yielded five phylogenetically distinct gene copies, two more th...
