ABSTRACT
Abstract: This study assessed the effect of pre-germination treatments on the germination and early growth of Tetrapleura tetraptera (Schum. & Thonn.). The seeds were extracted and subjected to the following treatments: Soaking in cold water for 24hrs (T1), dipping in hot water for 1minute (T2), soaking in coconut water for 30 minutes (T3), soaking in coconut milk for 30 minutes (T4), dipping in hydrogen peroxide for 1 minute (T5) and for the control (T6). The results showed that T3 had the highest germination value of 60% while T2 had the least of 25%. There was significant difference (p ≤ 0.05) in germination percentage between the treatments at 95% probability level. The seed treated with T3 had the highest mean seedling height of 44.54cm follow by mean seedling height (40.35cm) of both T1 and T6 (the control) while T5 had the lowest mean seedling height of 39.84cm. The ANOVA of the stem-collar diameters shows that there was no significant difference (P > 0.05) between the effects of the different treatment on the seedlings stem-collar diameter. The seedlings subjected to treatment T3 had the highest mean leaf number of 22 while the seedlings subjected to T1 and T6 had same lowest leaf number of 18. It was observed in this study that coconut water (T3) significantly did better in terms of seedling growth and development when used as a pre germination treatment for T. tetraptera seeds. However, the seeds when dipped in hot water for 1 minute (T2) as pre germination treatment did not significantly improve germination and growth of T. tetraptera seeds.
