The crane is a kind of potted flower with ornamental value. It is an excellent foliage plant. The common breeding methods include ramification, tissue culture and seed propagation. If large-scale production is required, tissue culture techniques must be used to reproduce, and in the process of reproduction, the application of tissue culture culture chambers is very necessary.
The seed germination rate was lower at the temperature of 22±2°C, which indicated that the germination temperature of the tested Helicoverpa quinquegorae seedlings required a higher temperature; the germination of the tested Helicoverpa quinquefolius seedlings was not different at the temperature of 24-30°C, and the germination rate was up to 16 d after sowing. 90%. In order to further explore the effect of temperature on the seed germination of Tetranychus urticae, an experiment should be carried out to explore the effect of temperature on the seed germination in the future, and the temperature of the Tetranychus urticae seeds is suitable for sowing.
The growth of Seed Germination and Seedlings of Betula horrida requires a medium with good air permeability, a suitable moisture and moist environment, and the best effect of sowing on the surface of peat; the light has a certain inhibitory effect on the germination of crucian carp, so it is in dark conditions or low Seeds of beneficial seeds germinate under light; usually, the temperature required for flowers originating in the tropics is relatively high, and the germination of the crucian carp requires higher temperatures. The optimum germination temperature is 24 to 30°C.
The cultivation and research results of the tissue culture room provided a theoretical basis for the scale production of the seedlings, which provided a reference for the hybridization, breeding and new species development of the new species of the crane in China. Different breeds of self-seeded seeds, hybrid seeds of different parents, and seed germination rates and growth rates for different seasons have yet to be explored in the future.
