陳俊仁、謝桑煙、胡文若。2004。斑葉月桃之微體繁殖。台南區農業改良場研究彙報43:11~17。

斑葉月桃利用莖頂培養在含MS添加BA 2mg/L和NAA 0.05mg/L的培養基中,能成功培養出具斑葉的新梢。利用定芽繼代培養建議每一培殖體有2或3芽。BA濃度控制在2或4 mg/L,大約1.5個月可繼代一次,每次可獲得3倍新梢。在液體比固體培養芽體長得大且快速。

發根以添加NAA 4 mg/L根數7.34條最多,根長0.76公分最適合移植。所有瓶苗後代皆能保持斑葉特性。

The Micropropagation of Shellflower (Alpinia speciosa K. Schum)

Chen, C. J., S. Y. Hsieh, and W. J. Hu

Summary

The shoots of Alpinia speciosa K. Schum were induced successfully from the shoot tips cultured on MS medium containing BA 2mg/L and NAA 0.05mg/L.  Each explant including two or three buds was suggested to subculture for multiplication.  Every 1.5 months each explant proliferated 3 times when the medium containing BA 2 or 4 mg/L.  The explants cultured in liquid grow bigger and faster than on solid medium.

The NAA 4 mg/L treatment has the highest root number 7.34, with the root length of 0.76cm that is suitable for transplant and all the offspring remain their variegated characters.

Key wordAlpinia speciosa., micropropagation, chimera
