Elicitors are substances that induce protective responses in plants. In this study, methyl jasmonate (Me-JA) and lysozyme elicitation on PLBs culture of Cymbidium insigne in vitro was investigated. Elicitation by 0.1 mg/l Me-JA enhanced maximum PLB, shoot and root formation. The effects of lysozyme under white fluorescent tube, results indicated that every concentrations of lysozyme induced PLB, shoot and root formation and 0.1 mg/l lysozyme enhanced maximum formation of PLB, shoot and root compare with control. Lysozyme is known to play a vital role in medical industry and the present study firstly used lysozyme, as a plant growth regulator in Cymbidium tissue culture.
