The ability of a plant to root, also known as the root's ability to recur, is closely linked to its survival rate. The stem cutting rooting is generally to form a root original body on a cambium and a vascular bundle sheath tissue of a base stem, so that an adventitious root grows out, a root system is formed, nutrition and moisture are absorbed, and the survival of a plant is ensured. However, the rooting ability of the aged trees is affected by factors such as increase of secondary metabolites, weakening of cambium stem cell activity and the like, so that the regeneration ability of roots is obviously reduced. Traditional plant growth hormones, such as auxins IAA (indoleacetic acid), IBA (indolebutyric acid), NAA (naphthylacetic acid) and the like, only have limited capability of promoting rooting of forest seedlings or adult seedlings, but have poor effect on aging trees.
How to promote the rooting capacity of woody plants is a problem to be solved urgently at present.
