SUMMARY

Growth of seedling structures of three accessions of Vitellaria paradoxa i.e. Makurdi, Jalingo and Kano, were investigated at Makurdi, Nigeria, in 2007. Ten (10) seeds per accession were planted in 7 litre plastic containers filled with weathered saw dust at the rate of one seed/container, with each seed representing a replicate. Weekly observations were made on the seeds for germination and growth of seedling structures. Results indicated that accessions differed with respect to days to appearance of swelling, length of radicle at which swelling appeared and shoot length above ground at the time of emergence. Percentage of seedlings that sprouted during the first week of observation differed in favour of Makurdi (80%) and Kano (60%) seeds, while seeds from Jalingo began sprouting after two weeks of planting.  Seedling emergence spanned from 51-79 days. In general the accessions followed the pattern of germination and growth expected of Vitellaria.  Time to formation of swelling and formation of shoot to its growth and emergence could account for the long time it takes for the seedling to emerge above ground. Efforts at hastening seedling emergence in this species should therefore focus on the above aspects
Key words:Accessions, growth, seedling structures, Vitellaria paradoxa
