Abstract
The relationship between seed weight, nutrient contents of seeds and germinating seeds of Acacia senegal (L.) Willd., Albizzia lebbeck (L.) Benth., Faidherbia albida (Del.) A. Chev., Piliostigma reticulatum (DC.) Hochst. and Prosopis juliflora (SW.) DC. was studied. Weighing of the seeds was carried out in the Department of Biological Sciences Laboratory for light, slightly heavy and heavy sized seeds, while nutrient composition of seeds and germlings were tested in the Animal Science Laboratory, Faculty of Agriculture and germination of seeds was conducted in the Laboratory of the Department of Biological Sciences. Completely Randomized Design (CRD) was employed. Proximate composition of seeds (ungerminated) and germlings (germinated) showed significant variation among the five species. Carbohydrate was the main food reserve in all the five seed species, followed by fibre, protein, lipid and then ash. Seeds of P. juliflora had the highest protein content (20.7%). A. lebbeck had the highest fibre content (26.3%). The seed with the highest lipid content was A. senegal (3.3%). Ash content was highest in seeds of A. senegal and F. albida (2.6%) and P. reticulatum had the highest carbohydrate content of (61.0%). Proximate composition of germlings showed depletion of carbohydrate and lipid contents while protein, fibre and ash increased in all the five tree species. Seed weight within and between species on nutrient composition was not significant at 5% probability except in fibre content. Seed weight within and between species on rate of germination was significant at 5% probability level but not significant on percentage germination. Seed weight between species indicated P. juliflora as the fastest 1-6days and highest percentage germination (98.75%) while P. reticulatum was the slowest 5-11 days and lowest (43.33%). In conclusion, among the species, germination was not influenced by seed weight and nutrient composition of the seeds but within species significantly influenced germinating seeds.
