Propagation of Argan (Argania Spinosa (L.) Skeels) by Seeds: Effects of Temperature and Soaking on Seed Germination of Two Taxa in Algeria

摘要

The aim of this study was to determine the germination characteristics of argania spinosa, the argan tree is a xerophitic species, found in semi-arid and arid climates that possesses. Specific ecological characteristics and holds interest in forestry,as fodder, and for its fruit. By regenerating the argan tree in the laboratory, we loamed that pre-soaking seeds for at least four days, contributes to successful germination. Our germination tests revealed a notably high germination rate 95% for seedspre-soaked in water for 96 and 120 hours in temperature of 30 ' C to 25 ° C and relatively high germination rates of 50% to 70% for seeds pre-soaked for 120 hours under a temperature of 22 ' C. The minimum germination rate (60%) was observed for seeds pre-soaked 96 hours at 22° C.
