The invention discloses a
tissue culture rooting method for Tama Tamarix jintaenia. The
tissue culture rooting method comprises the following steps: (1) a current-year
twig of Tama Tamarix jintaenia is selected and taken as an explant for rooting culture; (2) the explant is
cut into middle sections with the length of 10-15 cm,
sediment on the surface is washed away, and then deep cleaning is performed; (3) the explant is subjected to sterilization on an ultra-clean working table; (4) the explant is
cut into small sections with the length of 1.5-2.5 cm, and
inoculation is performed in a rooting culture medium (1 / 2 MS, IBA 0.4mg / l, and
sucrose 25g / l); (5) culture conditions are set: the temperature is 24+ / -2 DEG C, the illumination intensity is 1500-2000 lx, and the illumination time is 10-14 h / d. The method has the beneficial effects that Tama Tamarix jintaenia can root early and rapidly, first rooting occurs after five days, the rooting time is shortened to 15-21 days, the average
root length is about 9 cm after 21 days, roots are relatively long, the average quantity of the roots is 5, the quantity of
hair roots is large, the rooting percentage is 100%, the upper growth vigor is good, the
seedling cost is greatly reduced, and the industrial production of Tama Tamarix jintaenia is realized.
