The invention discloses a root
wetting method of a high-concentration IAA gel, belonging to the technical field of
plant biology. Firstly IAA mother solution of 1mg / mL is prepared; the mother solution is diluted into high-concentration IAA working solution of 500 mg / L; by using the working solution, high-concentration IAA gel confining liquid of
sodium carboxymethylcellulose with the
mass concentration of 1 percent and
sodium alginate with the
mass concentration of 8 percent is prepared; the lower end of a healthy, thick and
solid branch is wetted in the gel confining liquid for 3 to 5 seconds, and then is taken out; the
branch is inserted into a culture medium for rooting.
