GERMINATION AND EARLY GROWTH PERFORMANCE OF PREKESE, TETRAPLEURA TETRAPTERA TO SEED PRETREATMENT METHODS AND PHOSPHORUS FERTILIZER IN THE NURSERY PHASE

Abstract

Seeds of Tetrapleura tetraptera trees have poor germination due to their hard and impervious seed coat. This research was conducted to determine the possibilities of reducing seed dormancy using seed pretreatment via the application of sulphuric acid and hot water and then phosphorus for better seedling growth. Seeds pretreated with sulphuric acid had a significantly (P˂0.05) increased germination rate (by 60%) compared to seeds pretreated with hot water (40%). The application of phosphorus fertilizer stimulated the early growth of the species. This research provides information for practical use.
