Abstract:
OBJECTIVETo study the effects of potassium salts on direct induction of microtubers from different explants in Pinellia ternata.
METHODLeaves, petioles and tubers were cut and cultured on the medium with different kinds of potassium salts and plant growth regulators.
RESULT AND CONCLUSIONLow concentration of potassium salts, which were lower than 4.02 mmol x L(-1), could promote the microtuber formation in vitro. While high concentration of potassium salts, which were more than 12.06 mmol x L(-1), inhibited the formation of microtubers.
