BACKGROUND AND AIMS Seed dormancy enhances fitness by preventing seeds from germinating when the probability of seedling survival and recruitment is low. The onset of physical dormancy is sensitive to humidity during ripening; however, the implications of this mechanism for seed bank dynamics have not been quantified. This study proposes a model that describes how humidity-regulated dormancy on...

Raw and processed (soaked, soaked/boiled, roasted) wattle, Acacia saligna subspecies (subsp.) saligna, pruinescens, stolonifera and lindleyi, seeds were analysed for nutritional and antinutritional qualities. Whole wattle seeds mainly comprised proteins (27.6-32.6%) and carbohydrates (30.2-36.4%), which had approximately 12.0-14.0% fat and 13.0-15.0% crude fibre. Palmitic (9.6%), stearic (2.0%)...

Fabaceae (leguminous species) is the third-largest family of angiosperms. Floristical and vegetation analysis studies of wild leguminous species in Taif, Saudi Arabia were the prime aims of the current work. General survey of the studied area resulted to the selection of three different locations (Alshafa area (with its different habitats), Wadi seesed and Taif Hawia road (cutting many small wa...
