Analyze of Different Methods of Scarification and Biochemical Composition of Acacia Tortilis Subsp Raddiana Seeds

Abstract

Acacia totrtilis subsp raddiana or more commonly Acacia raddiana ; is one of the few leguminous shrub Saharan, which is of great interest to both ecological and economic.The objective of this work is to study the seed of Acacia raddiana, focusing both germination and its biochemical composition. Different scarification methods were used to lift the inhibition integumentary seed this taxon and hasten germination. We found that manual scarification has allowed obtaining a germination rate calculated at 85% and a latency of 24 hours. It proves to be the best method, followed by the pure sulfuric acid (98%). Scarification with boiling water gave poor results with a germination rate of 30% and a latency 192hours (8 days).The study of the biochemical composition of seeds of Acacia raddiana reveals that they are very poor in water (2.82%), but rich in dry matter (97.18%), and has an average lipid content (14 085%). Acacia raddiana seeds are low secondary metabolites: phenolic compounds (687.8μg / g dry plant material); flavonoids (0.339μg / g dry plant material) and anthocyanins (2.31 * 10-5 g / g dry plant material).
