Effect of seed germination box cultivation on seed production of wild chrysanthemum

The source of wild chrysanthemum is mainly collected in the wild, and the use of field resources will not only cause the destruction of ecological balance, but also will gradually reduce the sustainable growth and utilization of wild chrysanthemum plants. In order to ensure that the other functions and quality of the chrysanthemum are guaranteed without affecting the yield, it should be through a certain normative planting. Therefore, it is necessary to apply a seed germination box to study the propagation of the seed and the characteristics of the various aspects. In order to expand the production and cultivation methods of wild chrysanthemum seeds, the research on the cultivation of the seed germination box is a key technology. the study.

Effects of exogenous hormones on the germination of chrysanthemum seeds: 6-BA, NAA, IBA and control 4 groups were set up. The effects of different exogenous hormones on seed germination of chrysanthemum were observed through the seed germination box. All hormone concentrations were 100 mg/L and the test was repeated 3 times. Statistics of germination test data: Different treatments were conducted on the chrysanthemum seed to determine the germination rate, germination potential and germination index of the chrysanthemum seed. Germination rate = (total seed germination / number of test seeds) × 100%, indicating that the number of germinating seeds after the germination cycle is the proportion of total test seeds.

The germination rate of the control group was 82.10%, the germination potential was 54.7%, and the germination index was 28.84. The germination rate, germination potential and germination index of the acid treatment group were lower than those of the control group, indicating that the acid treatment had certain germination on the wild chrysanthemum seeds. The inhibitory effect; alkali treatment group germination rate was 68.30%, germination potential was 54.10%, lower than the control group, but the germination index was 32.17, slightly higher than the control group set seed germination box, indicating that the alkali treatment to a certain extent It can promote the rapid germination of wild chrysanthemum seeds, but the seed germination rate will be affected.

The seeds in the seed germination box passed the warm water treatment group, and the germination rate, germination power and germination index (the germination rate was 84.7%, the germination potential was 60.4%, the germination index was 30.77) were slightly higher than the control group, indicating that the warm water immersion can To a certain extent, the rapid germination of wild chrysanthemum seeds was promoted and the seed germination rate was increased. The germination rate, germination potential and germination index of the wild chrysanthemum water treatment group were all 0, indicating that the seeds of wild chrysanthemum had died and could not germinate under high temperature treatment.
