โฆ Synopsis
Somatic embryogenesis and plantlet formation were obtained from callus derived from the subapical region of spears of Asparagus cooperi Baker. Callus was obtained in Murashige and Skoog's medium supplemented with 1-naphthaleneacetic acid and kinetin. Increase in the concentration of potassium nitrate in subsequent subcultures resulted in the formation of embryos. Rapid multiplication of embryos was secured on transfer to a medium containing a different source of nitrogen and a low level (0.01 mg/1) of gibberellic acid. Media containing zeatin or gibberellic acid led to the formation of complete plantlets from embryos. Regenerated plants were cytologically and phenotypically stable.
