| titleOfInvention | A kind of cultivation method of triploid purple rain birch |
| abstract | The invention discloses a method for cultivating triploid Betula cerevisiae, belonging to the field of tree breeding. The method comprises: (1) birch seeds are induced by colchicine, and cultivated into tetraploid plants; (2) using birch and Northeast white birch as parents to hybridize to obtain diploid birch plants; (3) using The diploid Birch japonica is the male parent, and after collecting the pollen, it is dried in the shade for 24-48 hours and stored in vacuum for later use; (4) The tetraploid white birch is used as the female parent, and pollination is carried out at 9-10 am after removing the male inflorescence; (5) ) after pollination and continue to cultivate to obtain triploid Birch japonica seedlings. The present invention combines hybrid breeding and ploidy breeding, and obtains triploid Ziyu birch through leaf color investigation. This new variety has better cold resistance, and plays an important role in improving the ornamental quality of Ziyu birch and beautifying the urban environment. significance. |
