Variation of Vitellaria paradoxa phenophases along the north-south gradient in Mali
Research in Plant Biology, 1970 We monitored flowering, fruiting and leafing of Vitellaria paradoxa (shea tree) along the north–south gradient in Mali (West Africa), using three study sites for a period of three years. In each site, adult shea trees were marked and monitored in permanent plots of both field and fallow stands.
