Abstract:
Different nutrient media, temperature regimes, pH levels and photoperiods were evaluated to determine the best physiological conditions for the growth of Cephaleuros virescens. Among the six different nutrient media tested, agarized host leaf extract was found to be the best medium for maximum mycelial growth (51.11 mm) and growth rate (0.95 mm) with initially white to dull white mycelial growth that later turned green with time. Out of seven different temperature regimes tested, 25 °C was found to be the best temperature for mycelial growth (52.44 mm) with maximum growth rate (0.93 mm). Among the seven pH levels tested, pH 8.5 was found to be the best for promoting maximum mycelial growth (53.39 mm) and growth rate (0.88 mm). Among the photoperiods tested, 12h light conditions proved to be the best photoperiod in terms of maximum growth (65.35 mm) and growth rate (0.93 mm).
