ABSTRACT USE OF ZPT AND PLANTING MEDIA ON THE MYCELIUM GROWTH OF WHITE OYSTER MUSHROOM (Pleurotus ostreatus) Meyria Krusita Situmeang 1341014 White Oyster mushroom (Pleurotus ostreatus) is an alternative food for the society because of its high nutrients content. This study uses of ZPT and media to see the grow of the mycelium white oyster mushroom. Media used are the boiling water extract of nuts (green beans, soy bean, peanuts, beans of string bean, and beans of nut snaps) and ZPT (Naphthalene Acetic Acid and Kinetin). Anova was used to analyze the data at a significant level of α = 0.05. The results shows that: (1) There’s a significant effect of ZPT and Non-ZPT on the mycelium growth with p=0.000, Duncan Multiple Range Test (DMRT) shows that Kinetin is highest contribution to the significancy of Anova; (2) planting media used in the study shows a significant differences on the mycelium growth with p=0039, Duncan Multiple Range Test shows that beans of long bean and soy bean are the highest contribution to the significancy of Anova; (3) time/days of observation done in the study shows a significant differences on the mycelium growth with p=0000, Duncan Multiple Range Test shows that T6 or day 14 of observation shows the highest contribution to the significancy of Anova; (4) the interaction of ZPT, Non-ZPT and planting media show a significant differences on the mycelium growth p=0000; (5) the interaction of ZPT, Non-ZPT and time show a significant differences on the mycelium growth with p=0000; (6) the interaction of media and planting time show a significant differences on the mycelium growth with p=0000; and (7) the interaction of ZPT, Non-ZPT and planting media and time do not affect significantly the mycelium growth with p=0053. Key Word: Oyster mushroom (Pleurotus ostreatus), ZPT, Tissue Culture, Growth media.
