The requirements for mycelial
growth of Pleurotus florida, a Nigerian edible mushroom was carried
out. The carbon nitrogen ratio of 5:1 was found to be the most suitable
for the vegetative growth followed by 4:1 ratio and the least was 1:5.
The most suitable vitamin for the mycelial growth was thiamine followed
by pyridoxine while the least was cobalamine. With regard to phytohormones,
gibberellic acid was found to be the best for the mycelial growth followed
by indole acetic acid (IAA) while the poorest was 2, 4 dichlorophenoxy
acetic acid. Calcium was found to be the best required macro nutrient
while zinc was the best micronutrient. The implication of these results
was discussed.
