Long term conservation of seed pretreated by sulphuric acid
Mechanical scarification and soaking in sulphuric acid are the only known efficient pretreatments in order to break the tegumental inhibition of #Acacia raddiana# and #Faidherbia albida# seeds. Nevertheless, these two methods have serious contrains for development projects. Conservation for three years without significant loss of viability of #A. raddiana# seeds pretreated by, 95% sulphuric acid,solution is only possible at low temperature (5°C.). Under the same conditions results are also promising for #F. Albida# : 60% of the first years and 30% survive three years. These results may present an alternative solution consisting of storage of pretreated seeds and distribution of those ready to germinate.
