Callus Induction from Hypocotyl Explants in Tung Tree
Hypocotyl segments derived from tung tree aseptic seedlings were inoculated into the WMP medium with various hormonal combinations.
Therefore, the optimum medium for adventitious shoot induction from tung tree hypocotyl callus was WPM+1.0 mg L-1 6-BA+0.05 mg L-1 NAA+2.0 mg L-1 GA3.

This result indicated that KT dominated the multiplication of adventitious shoots derived from tung tree hypocotyls.
Shoot Elongation and Strengthening Culture in Tung Tree
The optimum media for tung tree rooting was 1/2 MS +0.1 mg L-1 IBA, with a rooting rate of 97.12%.

Establishment of a highly efficient regeneration system for tung tree will provide a convenient tool for tung tree tissue culture and transformation, thereby facilitating the transformation of foreign genes into tung tree.
In our previous study, we used the hormonal combinations developed for tung tree regeneration from leaves (Tan et al., 2013) to produce the regenerated plantlets using hypocotyl explants but failed, which further confirms hypocotyls and leaves contain different content of endogenous hormones.
