Abstract

This study aimed to investigate the variation of SOIL SEED BANK density, richness and its similarity with above-ground vegetation in different distances from WATER POINT in Kahnuj rangelands. Soil sampling was carried out after seed dispersion within two soil depths (0-5 and 5-10 cm) around three WATER POINTs at intervals of 0, 20, 50, 100, 120, 150, 200 and 300 m to WATER POINTs. Soil samples were spread in the green house after cold treatment. Seedling was identified after germination, counted and removed once each 10 days. Above-ground vegetation composition was determined during growing season to estimate the similarity between SOIL SEED BANK and vegetation. General Linear Model was done to compare SOIL SEED BANK characteristics between different distances to WATER POINTs and depths. Results showed that the soil seed density was significantly different between the distances, with the lowest at nearest and the highest at furthest distances to WATER POINTs. In spite of absence of the plant cover at nearest distance, some seeds germinated from soil. Although, the richness was significantly different between the distances, there was no any specific trend in seed richness with distance gradient. Similarity between SOIL SEED BANK and above ground vegetation was increased with increasing the distance-to-WATER POINTs. In overall, the highest seed density was related to annual species. Despite the presence of tree and shrub species in the ground VEGETATION COVERs, they were not presented in the SOIL SEED BANK.
