Abstract: Some results have been obtained with experiments on seed domancy and germinayion of (?)ibriunn macrocephalum. The seeds need a long warm period to break the domancy of hypocotyledonary axis before germinating. With the sowing dates during spring and summer seasons postponed, not only germination dates were usually relatively delayed, but the germination percentage was decreased. Germination dates and percentage always varied with sowing dates. According to our researches, the best way of propagation by seeds is to store seeds in sand to maintain moisture, and then to sow them in the following autumn.
