Abstract

Stems of tissue culture seedlings of Ormosia henryi were cultured under low temperature stress. The results showed that the optimal temperature for induction of chilling tolerance callus was 5℃. The differentiation frequency of chilling tolerance callus cultured under 5℃ was 70.0% on MS solid medium supplemented with 6-BA 2.0 mg/L and NAA 0.25 mg/L, and the injury rate of regenerated plants from chilling tolerant callus was much lower than that of control group.

Key words： Ormosia henryi; low temperature stress; chilling tolerance
