AI Technical Summary
There are currently no reports of aseptic bud rooting and seedling production from tung tree. Existing technologies for inducing bud rooting from tung tree hypocotyls are difficult and have low survival rates, presenting a technical bottleneck.
A method for aseptic bud rooting of tung trees is provided, which includes sterilizing the tung tree hypocotyl and culturing it in a bud induction medium to obtain apical buds. Then, the apical buds that germinate from the 12-month-old tung tree hypocotyls are inoculated into a rooting medium and cultured using an optimized rooting medium formula such as MS + KT 2.0 mg/L + NAA 0.1 mg/L + zinc oxide 0.05 mg/L.
The breakthrough in the tissue culture technology of tung tree has achieved efficient rooting, high rooting rate, and excellent seedling growth. It fills the gap in the technology of regulating the bud age of tung tree hypocotyl-induced rooting and has broad application prospects.
