Determination of Phenology, Seed Germination and Development of Hura crepitans using Chemical Scarifications

M. Idu, A.C. Omonhinmin and H.I. Onyibe
The phenology, seed germination, seedling development and evaluation were carried out on the seeds of Hura cepitans. The phenological data describes Hura crepitans seeds as 0.94 g in weight, 2.3x2.2x.48 cm in size; 3.6 cm3 mean volume, of 78% moisture level. The capsule of length 8 cm contains 7-16 seeds. The seeds are circular in shape, smooth, glabrous and glossy in texture with a capsule depth of 2.5 cm and a brownish testa. The plant flowers and fruits from the end of October to the end of June. To break dormancy, investigations on the stimulatory effect of chemical scarifications were analyzed. Methanol pre-treatment recorded the highest of 70% germination. Comparatively, some of the pretreatments showed better germination energy and vigour than the control. Such pretreatments are good for germination and nursery establishment of the species.
