Abstract

The present work was undertaken to study the growth pattern of Drummondia stricta (Mitt.) Müll. Hal. in six different culture media with a combination of auxin and cytokinins, using spores as explants in aseptic cultures. In Drummondia, there is a tendency of multicellular spore formation and spore germination is precocious and endosporic. It has been observed that plant growth was the most satisfactory in the ½ Knop’s + 0.1 mg/L IAA + 0.1 mg/L Kinetin followed by ½ Knop’s, 0.1 mg/L IAA + 0.1 mg/L BAP. However, no growth was observed in case of ½ KNOP’s and Hoagland media.

Keywords:
