Study on Promoting Provenance Breeding of Forest Germplasm Resources
The forest is often referred to as the “Oxygen Barâ€, while the trees in the forest are the main source of oxygen. The survival and development of mankind cannot be separated from the abundant forest resources. Therefore, promoting the sustainable development of forestry is to promote the sustainable development of mankind. In the current process of forest resources conservation and upgrading, forest germplasm resources have become the focus of attention. In order to further accelerate the protection of germplasm resources and promote the research of provenance breeding, the demand for forest germplasm resources is growing.
We know that breeding is inseparable from breeding materials, as is forest breeding. In order to obtain and utilize excellent genetic materials, on the one hand, it is necessary to increase the collection of forest germplasm resources, so that more forest germplasm resources can be discovered and protected by science; on the other hand, Increase the development and utilization of forest germplasm resources, and use the abundant germplasm resources collected from the forest germplasm resources to promote the research of provenance breeding, and provide support for the high-quality development of the forestry industry.
The importance of forest germplasm resources is self-evident for the sustainable development of forestry industry. However, many forest germplasm resources are facing survival problems due to environmental and human influences. In the process of carrying out forest germplasm resources, these endangered forest resources should also be rescued and stored in a proper manner. The forest germplasm resource bank belongs to different places, and the way to preserve germplasm resources in the facility, using its technical methods, can not only preserve these endangered forest germplasm resources for a long time, but also accelerate the development and utilization of improved species and promote the breeding of provenances. To help the industry develop.
At present, the emphasis on forest planting resources is increasing, and the demand for forest germplasm resources is increasing. To ensure the quality of construction, we recommend that all relevant departments choose companies with experience and technical strength to cooperate. Top Yunnon is the ideal choice.
