Abstract

The study was conducted to determine the germination response of ten genetic resource materials of yemane (Gmelina arborea Roxb.) to acidic and alkaline soil germination media. Results of the study reveal significant differences between two germination media and between 10 mother trees on germination capacity and germination energy. However, there was no interactive effect observed between soil pH levels and mother trees in all aspects of the germination parameters. Acidic soil (pH 6.8) outperformed alkaline soil (pH 7.5) in percent germination (49.4% and 44.40%, respectively) and germination energy (43% and 42%, respectively) but no significant differences on the latter parameter. Germination time is significantly different between two germination media with the lowest germination time of 16 days in alkaline soil and 19 days in acidic soil. The best genetic resource materials for yemane in terms of percent germination capacity and germination energy were Mother Tree 4 (80%) and Mother Tree 3 (78%). On the other hand, the fastest to germinate was Mother Tree 10 with 13.8 days germination time. The information provided contributes to the scanty scientific knowledge on the silviculture of Gmelina arborea Roxb. specifically in establishing a protocol for seed germination.
