Effect of Copper on Growth and Development,Fruiting Body Quality and Copper Content of Pleurotus ostreatus
Abstract：Mycelial growth,primordia formation,yield,fruiting body quality and copper content were stud-ied under different concentrations of copper so as to explore the response mechanism to copper in Pleuro-tus ostreatus. The results showed that the effects of copper on mycelial growth,primordia formation,yield, contents of amino acid,total protein and crude fat were significantly concentration-dependent. The growth speed of mycelia had maximum value and primordial formation was 2 days earlier than that of control un-der 1500 mg/kg of copper. The yield( dry weight) was the highest under 500 mg/kg of copper. The con-tents of amino acids,total protein and crude fat all reached maximal values under 1000 mg/kg of copper, which were 16. 00%,24. 88% and 2. 34% respectively. However,the copper contents in stipe and pileus gradually increased with the increase of copper concentration(0—3000 mg/kg) .
