Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2018, Vol 11, Issue 11
Abstract
The present study conducted at KhulaisNational Park , West Saudi Arabia, to assess soil seed bank, and above ground vegetation.A total of 28 emerging seedlings of plant species belonging to 7 families were recorded in the soil seed bank samples during the germination period. From the emerged seedlings 81.5% were annuals and 18.5% perennials. The range of variation between life forms was small. The dominant families were ( Poaceae , Fabaceaesub.f. Mimisoideae and Portulacaceae)The most dominant species were Acacia ehrenbergian, Eragoristis species, Panicumturgidum, Dactyloniumaegyptiacum, Zygophyllum simplex andportulacaquadrifidaThe density of live soil seed banks in the study area was 80 seeds/m2, which consider as viable seeds.The above ground vegetation cover of the study area was determined in order to compare it is floristic composition with that of the soil seed bank. A total of 45 species were identified to represent the habitats of the study area. The most dominant family in the study area is Poaceae (Graminae).The similarity between above ground vegetation and live soil seed bank of the area in question was found to be 30.6%. This is considered a low index of similarity ,according to Sorensen (1948).
