| 摘 要： | 珙桐种子繁殖和扦插繁殖的生物学特性研究，弄清了种子休眠的主要原因在于种胚形态后熟和生理后熟，探讨了种子休眠萌发机理，用人工低温冷冻或ＧＡ＋６－ＢＡ处理，可使层积２年尚未萌发的种子７０％左右在半月内迅速萌发出苗，缩短休眠期约１年，经不同处理的扦插试验，５％的插条可生根成苗。

| Abstract: | The whole process of seed and cutting propagation of Davidia involucrataBaill was researched.The main cause of its seed dormancy was afterripening of seed-embryo and seed-physiology.The mechanism of seed dormancy and germination was discussed.Seeds of two-year sand-storage treatment could be germinated up to 70% of surviving rate by means of freezing or GA 6-BA in 15 dyas, which shortened one year time of its seed dormancy.In cutting, 5% rooting rate was the best one among various treatments. |
