Abstract:   (5472 Views)

In this study the effects of different geographical aspects (north and south-east faced slopes) and grazing intensities (light, moderate and heavy grazing intensities) on the growth condition of Festuca ovina L. in Sabalan rangelands were investigated. Total rangeland productions under various grazing intensities and rangeland conditions (e.g. good, fair and poor) were measured by establishing 30 plots in each aspect. Three transects with 50 meters lengths were established in various grazing intensities on both aspects. Ten F. ovina bunches were selected randomly and their above and below grounds were collected, air dried and weighed in the flowering stage. Quantitative traits such as the species above and belowground dry matter, root length, aerial height, inflorescence length under various grazing intensities and aspects were measured. According to ANOVA, the species mean dry matters were significantly different in various grazing intensities and aspects (p <0.01).  The measured traits under the same grazing intensities were higher in south-east aspect compared to the north aspects. The measured traits of the species were differed significantly under heavy grazing pressure between the various slope sites (p<0.01). This study highlights physiological and morphogenesis responses of  F. ovina to grazing pressure and environmental properties such as sunlight and aspects. This information can be used to achieve sound management strategies in Sabalan rangelands.
