The invention provides a radix pseudostell adventitious root induction method and a radix pseudostell adventitious root tissue culture method of the medicinal technical field, which comprises that (1) a poisoned radix pseudostell explant is cancelled, and is inoculated on a callus tissue induction culture base after being cut under the bacteria-free condition, and the callus tissue is induced under the bacteria-free light-free condition; (2) the callus tissue that is grown fast with light-yellow color is fetched to be arranged on a 1/2MS solid culture base comprising one or more plant hormones of the seradix, the rhodofix and the kinetin to be induced to form a adventitious root under the bacteria-free light-free condition; (3) liquid culture of the radix pseudostell adventitious root-theobtained adventitious root is arranged in a 1/2MS liquid culture base comprising one or more plant hormones of the seradix, the rhodofix and the kinetin to be cultivated. The method of the inventionis simple and the efficiency is high; the adventitious root induction rate of the explant of the stem and the leaves of the radix pseudostell reaches more than 90 percent. The adventitious root growsfast with less inoculation and the growth rate can reach more than 46 times after being cultured in a bottle for 18 days.
