Induction of plantlets on inflorescence of phalaenopsis by application of N-6-Benzyl adenine

บทคัดย่อ

Clonal propagation of Phalaenopsis can be accomplished by division of plantlets spontaneously formed on the inflorescence node and tip, or on root in some of Phalaenopsis species and hybrids. Plantlets can also be induced by top cutting. These current as esexual methods yielded only a few plants of a clone per year. In an attempt to induce plantlet formation on the inflorescences, various concentrations of N-6-benzyl adenine (BA) in lanolin were applied on the dormant buds after removing the bracts, or at the tip of inflorescences. The most effective method was the application of 2000 ppm BA on dormant buds of the lower nodes of inflorescences after removal of the bract.
