摘要：
Effect of mechanical scarification, dry heat, hot water, and sulphuric acid on the germination behavior of Cistus populifolius L. (rockrose) was studied. Untreated seeds after 60 days of incubation germinated less than 7%. After thermal treatments, 90% germination was achieved, and sulphuric acid pretreatment gave 61% germination. Soaking in distilled water did not increase germination, but scarification of the seed coat gave 57%. Hardness and impermeability of the seed coat appear to cause deep dormancy in C. populifolius seeds.
