The Biological Characteristics in Dovetree Davidia involucrata Propagation

    Graphical Abstract
    • Abstract
  • The whole process of seed and cutting propagation of Davidia involucrata Baill 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.
