摘要

The in vitro growth of Ganoderma mycelia on six agro-wastes namely, broad bean stalks (BBS), cotton stalk (CS), maize straw (MS), rice straw (RS), sugarcane bagasse (SCB) and wheat straw (WS) supplemented with wheat bran (WB) or corn gluten (CG) was evaluated. Among the substrates used, CS appeared best followed by SCB and RS. WB showed best supplementation for mycelial growth. CO2 emission values exhibited accurate measurements to decide the suitability of such agro-waste for growth rather than visual observations. CS+RS+SCB+WB in combination proven its superiority for in vitro growth and active spawn development substrate. In mushroom house, this particular formula proved its superiority and was on par with recommended EG formula; it gave the highest yield (195.16 g Kg(-1)), biological efficiency (19.52%), protein (16.69%), polysaccharides (3.613%) and minerals (3433 mg/100 g). Spawn running period was the shortest in treatments inoculated with agro-waste-based spawns. With 40% biochar, days required to the complete mycelium colonization and fructification were 10.60 and 23.00, respectively. At 10% biochar, highest yields (238.40 g Kg(-1)), biological efficiencies (23.84%), protein (19.58%) and minerals (4092 mg/100 g) were obtained. The higher the biochar level, the higher the reduction in emitted CO2, the loss in C and the increase in N of Ganoderma post mushroom substrates (GPMSs). Under greenhouse conditions, almost all the tested GPMSs, at 0.125 or 0.25%, encouraged the reproduction of reniform nematodes and improved plant growth criteria. (C) 2019 Published by Elsevier Ltd.
