Title

THE STUDY OF THE EFFECT OF SLOPE ASPECTS ON THE PRODUCTION OF TRAGACANTH IN ASTRAGALUS HYPSOGETON BUNGE. IN NORTH KHORASAN

Pages

  53-60

Abstract

GUM TRAGACANTH is a natural dried secretion produced by some species of Astragalus which is considered as a high quality hydrocolloid used extensively in food industry, pharmacology, medicine, and textile industry. GUM TRAGACANTH producing species of Astragalus are mainly spiny and xerophyte that are spread in mountainous and destroyed rangelands. Density and yield of these species in different SLOPE ASPECTs vary due to significant changes of rainfall and humidity, grazing intensity, erosion and soil structure. In order to investigate these variations in GUM TRAGACANTH of Astragalus hypsogeton in MOUNT BAHAR exploitation program in NORTH KHORASAN, the GUM TRAGACANTH yields were sampled in four cardinal directions of slopes. Analysis of variance of the data and comparisons of the means based on Duncan Multiple Range test, showed that GUM TRAGACANTH yield in southern aspects was more than that of other aspects because of increasing density and vegetative cover of Astragalus due to moisture shortage of soil in this aspect in comparison with the other aspects, in particular Northern aspect, and as a consequence elimination of main and key species of the rangeland and substitution of the invasive Astragalus.
