Abstract
Stratification for 60 days at 5°C was found to increase the germination percentage of Juniperus excelsa seeds fom Eritrea (63%) over untreated controls grown in a greenhouse (53%) and a growth chamber (47%). Scarification with H2SO4 for 15 min did not significantly improve germination percentage over untreated controls. Treatment with hot water resulted in zero germination after 240 days, while scarification in H2SO4 for 60 min significantly reduced germination percentage (7% and 8%). There were significant differences in germination percentage between seeds from different maternal plants (18 to 60%). Results presented in this study differ from those reported for J. excelsa seeds from Tanzania, possibly due to differences in provenance and duration of seed storage.Keywords
