Effect of Different Presowing Treatments to Break Seed Dormancy and Seed Collection Methods on the Germination of Dracaena steudneri Schweinf. Ex Engl.

Research Highlights: This study is focused on the germination of Dracaena steudneri Schweinf. Ex Engl. seeds using different presowing treatments. Background and Objectives: The aimed to overcome problem breaking seed dormancy, facilitate artificial regeneration for conservation development purposes. objectives this were (1) evaluate effect treatments in dormancy D. (2) assess collection method (seeds collected ground vs. from tree) seed. Materials Methods: experimental with seed-dormancy-breaking was carried out a greenhouse laboratory. T testing one way analysis variance (ANOVA) used analyse data. Results: applied (hot water, cold sodium hypochlorite nicking) did not improve species, nor dormancy. One-way ANOVA results also showed no significant differences between control mean species (p < 0.05). t test result revealed fallen tree crown tetrazolium that percentage nonviable greater than viable seeds. Conclusion: (ranging 0%–7%) laboratory (0%), which might be due intermediate characteristics species. Therefore, we recommend more research undertaken ecophysiology order understand mechanisms controlling its germination.
