Embodiment 1
[0028] A kind of crape myrtle anti-lodging planting method that the present embodiment provides, described method comprises the steps:
[0029] Step 1. Selecting parents: selecting crape myrtle from different origins with good stress resistance, fast growth, thick stalks and low fiber content as parents of tetraploid breeding source plants;
[0030] Step 2. Induction: When the flower buds of Lagerstroemia indica parents are not open, chemical inducers are used to induce the flower buds, so that the chromosomes of the flower organs are multiplied, so that they can produce male and female gametes containing two sets of chromosomes;
[0031] Step 3, hybridization: hybridize the induced flower buds with the normal flower buds for pollination, and obtain hybrid seeds after the plants become fruity;
[0032] Step 4, detection: the hybrid seeds are cultivated into seedlings by aseptic sowing, and tetraploid plants are detected;
[0033] Step 5, asexual reproduction: asexual reproduc...
Embodiment 2
[0045] A kind of crape myrtle anti-lodging planting method that the present embodiment provides, described method comprises the steps:

Embodiment 3
[0062] A kind of crape myrtle anti-lodging planting method that the present embodiment provides, described method comprises the steps:
[0063] Step 1. Selecting parents: selecting crape myrtle from different origins with good stress resistance, fast growth, thick stalks and low fiber content as parents of tetraploid breeding source plants;
[0064] Step 2. Induction: When the flower buds of Lagerstroemia indica parents are not open, chemical inducers are used to induce the flower buds, so that the chromosomes of the flower organs are multiplied, so that they can produce male and female gametes containing two sets of chromosomes;
[0065] Step 3, hybridization: hybridize the induced flower buds with the normal flower buds for pollination, and obtain hybrid seeds after the plants become fruity;
[0066] Step 4, detection: the hybrid seeds are cultivated into seedlings by aseptic sowing, and tetraploid plants are detected;
[0067] Step 5, asexual reproduction: asexual reproduc...
