Effects of various hormonal treated plant substrates on development and yield of Pleurotus ostreatus

Abstract

Effects of various hormonally treated substrates on mycelial development, pinning and biomass of Pleurotus ostreatus were investigated. A 3 × 4 experimental layout was used i.e. three substrates: Urochloa panicoides, Zea mays and Datura stramonium and four hormonal treatments: cytokinins; auxins; gibberellins and control. Treatments were replicated three times and arranged in a Completely Randomize Block Design. The results indicated significant differences on mycelial, pinning, fruit caps and biomass (p ≤ 0.05). Mycelial development in respective substrates was as follows: U. panicoides (100%), Z. mays (84.78%) and D. stramonium (36.31%) and pinning rate was 65.48, 32.99, and 12.23% respectively. Hormones also had significant effect on cap size and style length (p ≤ 0.05). Cap sizes were: auxins: 13.42 cm, cytokinins: 9.9 cm and gibberellins: 7.13 cm and style lengths were: 6.93, 8.83 and 11.03 cm respectively. Mushroom biomasses from different substrates were: U. panicoides (7,609.56 g), Z. mays (7,296.42 g) and D. stramonium (4,368.15 g) indicating significant influence of substrate on mushroom biomass.
