This study examined the effect of seed source and pre-sowing treatment on germination of Canarium schweinfurthii [Engl] seeds. The seeds were sourced from Unubi in Anambra state (T1) and Jos in Plateau state (T2) in Nigeria. The experiment was conducted at the University of Benin and lasted for 14 weeks. It was laid out in a completely randomized design (CRD) pattern using 2x7 factorial combinations of 2 sources and 7 pre-sowing treatments. The pre-sowing treatments were complete removal of seed coat (CR), partial cracking (PC), burning under dry grass (BG), 70% H2S04 (7H), 80% H2S04 (8H), 3 days (72 hours) soaking in water (SW) and control (CT). Germination parameters investigated were days to germination, germination percentage, germination energy, germination period and germination value. Data collected were subjected to Analysis of variance (ANOVA) at 5% significance and significant means were separated using LSD. There was no significant difference in the mean days to germination (20.7 days in T1 and 21 days for T2) and mean germination percentages (31.14% in T1 and 31.71% for T2) of the sources. The treatments days to germination were significantly different with CR being the first to germinate (12 days) while 7H germinated last (41 days). There was significant difference in the mean germination period (31.71 days in T1 and 23.57 days for T2), germination energy (1.24 in T1 and 2.38 for T2) and germination values (0.3 in T1 and 0.54 for T2) in the investigated sources, while the mean germination percentages of the pre-sowing treatments irrespective of source were significantly different. Treatments BG had the best mean germination percentage followed by treatment SW and CT while 8H had the poorest. It is therefore recommended that treatment BG is the best followed by SW for increase in germination percentage. But where seedlings are needed in little quantity within a short time, treatments CR and PC are recommended. Acid treatment is unsuitable for the seeds of Canarium schweinfurthii.

The effects of seed pre-treatment methods on the germination and growth of Myrianthus arboreus under two light regimes was conducted in the nursery of the Department of Forest Resources and Wildlife Management, University of Benin, Benin City. The seed pre-treatment methods were 24 hours soaking in water (T1), 12 hours soaking in water (T2), seeds tied in black nylon (T3), control no treatment (T4) and repeated under two light regimes which were open light regime and medium light regime. Experiment was set up in Completely Randomized Design manner (CRD.) Analysis of variance was used to analyze the results of germination and growth parameters measured. Germination percentages in the open light regime were 52, 56, 52 and 56% for T1, T2,T3, and T4 respectively while germination percentage in the medium light regime were 100, 64, 0 and 32% for T1, T2, T3, and T4 respectively. The mean shoot heights (cm) were 10.22 and 5.36 in the open light regime and medium light regime respectively. Collar girths (mm) were 1.99 and 1.11 number of leaves were 3.39 and 2.23 while the mean shoot to root ratio was 1.01 and 0.99 for the open light regime and the medium light regime respectively. Therefore, it is recommended that the seeds of Myrianthus arboreus be soaked in water for 24 hours, sown under medium transferred at the 2-leaf stage to the open light regime (or shading removed) where they will grow until planting out time.
