Growth of F0 seedlings of oysters mushroom (Pleurotus ostreatus) with different ages of explants

Abstract

The success of oyster mushroom cultivation is determined by the quality of seed and the planting media used and environmental factors. This research aimed to obtain quality oyster mushrooms F0 seed based on the type of mushrooms and ages of different explants. The experiment was conducted at the National Agriculture Training Center in Batangkaluku from January to April 2018. The trial was set using factorial randomized block design method with two factors. The first factor was the type of oysters mushroom, namely white oysters mushroom and brown oysters mushroom. The second factor was the difference in the age after the growth of pinhead, consisting of 3 levels, namely 1 day, 3 days and 5 days. There were 6 combination treatments repeated 4 times, resulted in 24 treatment units, and each treatment unit used 3 units as observation object, bringing the total to 72 treatment units. The results show that the interaction between the type of white oysters mushroom and age 5 days after the growth of pinhead provided the best response to the diameter of mycelium F0 (2.84 cm) and the density level of mycelium F0 that categorized as thick density (score 4.17). The largest mycelium thickness, with a score of 3.42, ie. mycelium grows thinly evenly. The treatment of oysters mushroom gave the best response to white oysters mushroom, while the treatment of age after pinhead growth gave the best response at the age of 3 days.
