英文摘要 | Mixed broadleaf Korean pine (Pinus koraiensis) forests were once extensively distributed from north-east China to the far-east of Russia, but are now in need of restoration as they have almost disappeared after more than a century of extreme disturbance. Seed dormancy in Korean pine is a major constraint to its regeneration and to restoration of the forest. Understanding how moist cold stratification releases the dormancy is important for direct seeding in the forest and for nursery production of seedlings. Both imbibed and dry seeds were buried in the forest soil at 100 and 500 mm depths. Variables studied were concentrations of abscisic acid and gibberellic acid, embryo growth, respiration rates and germination. Although burying imbibed seeds at 500 mm depth was most effective in breaking dormancy, burying imbibed seeds at 100 mm gave similar results. Therefore, directly sowing imbibed Korean pine seeds in the forest appears to be an option for restoring the species. |
