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.
Auxin, Cytokinins, Endosporic, Multicellular spores.
