|Title of the thesis:||Effect of seed treatment on the germination of different provenances of Dodonaea angustifolia; a recommendation for degraded land restoration through direct seeding|
|Summary:||In Jara Jinesa nursery site in Ethiopia near Awassa city an experiment on germination rates of Dodonaea angustifolia was realized in 2015. To examine this rate, three different provenaces were evaluated for four different seed treatment methods and compared with control sample of untreated seeds. Hot water treatment at both time intervals prove significantly positive effect on seed germination. After this treatment seeds germination rate reached from 70 to 100 %. The positive effect of seeds soaking in cold water has not been recorded, in some cases even reduced germination over any untreated seed. Within 3 to 6 days of sowing, especially in warm water treated seeds, the number of germinated seeds increases steeply. The impact of provenance is evident especially in the various time span optimization, since each provenance is adapted to specific environmental conditions. Treating seeds with warm water before sowing increased the uniformity of seedlings, thereby increased the quality of seed production without significant technological equipment and financial costs|
