Abstract
Study was conducted at Savanna Forestry Research Station Samaru, Zaria to evaluate effect of different pre-germination treatments on the germination and early growth of Balanites aegyptiaca seeds. The treatments includes partial cracking of seed, partial burning of seed, removal of seed coat, soaking in boiling water and untreated control. The experiments was laid out in a completely randomized design with five replication. The results of the germination test shows significantly (P<0.05) higher germination percentage among all treatments. Partially cracked seed recorded highest (67.3%) germination and seed with removed seed coat (45.6%) had the lowest germination among all the pre-germination treatments, while untreated control (9.6%) recorded the least germination. There were no significant (P>0.05) difference in the growth of B. aegyptiaca seedling among pre-germination treatments, although partially cracked seed (5.81cm and 7.40) recorded the highest seedling height and number of leaves, while seed with removed seed coat (5.61cm and 6.87) had the lowest seedling height and number of leaves respectively. The control (0.71cm and 0.71) recorded the least seedling height and number of leaves during the study period. The above findings has shown the potential of all the pre-germination treatments especially partial cracking of seed coat as most effective mechanism to break the dormancy of the seed in order to initiate germination and growth for efficient plantation establishment.
