Abstract:

Effects of various hormonal treated substrates were investigated on mycelia, pinning and biomass of Pleurotus ostreatus. A 3 x 4 experimental layout was used i.e., three substrates: Urochloa panicoides, Zea mays and Datura stramonium and four hormones: Cytokinins; Auxins; Gibberellins and Control. Treatments were replicated three times (CRBD). The results indicated a significant difference (pâ?¤0.05) on mycelia, pinning, fruit cabs and biomass. Mycelia on substrates showed: U. panicoides (100%), Z. mays (84.78%) and D. stramonium (36.31%). Pinning rate was: U. panicoide (65.48%), Z. may (32.99%) and D. stramonium (12.23%). Hormones were also noted to have a significant effect (pâ?¤0.05) on fruit cap size and style length. Cap size observed was: Auxins: 19.3 cm, Gibberellins: 8.25 cm and Cytokinins: 7.1 cm and style length: Auxins: 8.9 cm, Gibberellins: 13 cm and Cytokinins: 10.3 cm. Biomass on different substrates showed: U. panicoides (7609.56g), Z. mays (7296.42g) and D. stramonium (4368.15g). From the results it can be deduced that mushroom biomass is influenced by substrate.
