Embodiment Construction
[0018] Aiming at the problems of long time, many materials and low work efficiency in identifying the salt-tolerant potential of plants by traditional techniques, the inventors conducted a lot of research work, and finally established a new method for identifying the salt-tolerant potential of poplar by using the stress-resistant ability of detached leaves. method. Based on the relative conductivity of detached leaves at a certain salt concentration, the salt-tolerant potential of different genotypes can be quickly and accurately determined, thereby screening excellent genotypes with high salt-tolerant potential, and eliminating a large number of useless genotypes in a short period of time. materials, and then bred new varieties of poplar with good salt tolerance.
[0019] The present invention aims to provide a scientific and efficient salt-tolerant rapid identification method, through which a large number of salt-intolerant genotypes are eliminated, the combination of salt-t...
