Example Embodiment
[0027] Example 1
[0028] The present embodiment provides a method for planting crape myrtle against lodging, the method includes the following steps:
[0029] Step 1. Choose parents: choose crape myrtle from different producing areas with good stress resistance, fast growth, thick stalk, and low fiber content as the parents of tetraploid cultivation source plants;
[0030] Step 2. Induction: When the flower buds of the crape myrtle parent are not open, chemical inducers are used to induce the flower buds to double the chromosomes of the flower organs to produce male and female gametes with two sets of chromosomes;
[0031] Step 3. Hybridization: pollinate the induced flower buds with normal flower buds, and obtain hybrid seeds after the plants are set;
[0032] Step 4. Detection: The hybrid seeds are cultivated into seedlings by aseptic sowing, and the tetraploid plants are detected;
[0033] Step 5. Asexual reproduction: Asexual reproduction of tetraploid plants to obtain a large numbe...
