To promote the diversity and stability of forest plant species and promote the healthy development of forestry, it is necessary to increase the protection of forest germplasm resources, and the protection of forest germplasm resources cannot be separated from the forest germplasm resource pool . Support, so they are interlocking and closely related. So what exactly is tree germplasm resources and what is the tree germplasm resource bank? What are the important implications of using forest germplasm resources to carry out the protection of forest germplasm resources? This article will provide detailed answers for everyone.
1. What is forest germplasm resources?
Forest germplasm resources refer to the basic materials for breeding new varieties of forest trees, including cultivars of various trees, propagation materials of wild species, and genetic materials of various trees artificially innovated using the above-mentioned propagation materials. Forest tree germplasm resources are the carrier of the genetic diversity of forest trees and an important part of species diversity. They are the basic materials for forest tree breeding and are important national strategic resources.
2. What is a forest germplasm resource bank?
The Forest Germplasm Resource Bank refers to the use of seed cryogenic preservation, ultra-low temperature preservation and in vitro preservation of germplasm to preserve seed germplasm resources and their related wild plants. Its preserved materials can be readily available for scientific research, teaching, breeding, and international exchange.
3. The significance of using forest germplasm resource pool to carry out protection of forest germplasm resources
Forest germplasm resources are precious human wealth. At this stage, with the influence of human activities and changes in the climate and environment, many fine tree species have become rare species and are on the verge of extinction. Through the establishment of the forest germplasm resource bank, first of all, it can provide a reliable place for the long-term preservation of these rare and endangered tree species, so that it can continue to be retained. Next, the forest germplasm resource pool will also provide reasonable development and utilization of forest germplasm resources. Convenience provides sufficient genetic materials for the cultivation of good seedlings and strong breeding of native tree species in the future, which is of great significance for promoting the sustainable development of forestry.
*Pump color: blue
*Contains trip-function valve
*Different type of material provides: PVC, PVDF, stainless
*Ball check valves: it through double valve ball, seat and sleeve to form the sealing system, that enhance the precision
*High speed operation: high measurement precisions, up to 360 strokes per minute which eliminate the pulsation effect.
