Assessing evolution with time of Dacryodes crassiflora seeds germination under various nusrsery conditions in humid tropics

The study was carried out to assess Dacryodes crassiflora seeds germination ability under various nursery conditions. Two factors were studies: Scarification (Yes or no) and nature of substrate (top soil, sawdust, sand, and a mixed up of sand and top soil).The trial was set up as a randomized complete block design with tree repetitions, 30 seeds per experimental unit. Individual seed germination status were recorded in the binary form (germinate or not; died or not) on a weekly basis from the fisrt week after sowing to the fifteen weeks.
