Pleurotus geesteranus strain production method for increasing fruit body yield and total amino acid content with cobalt 60 radiation treatment

Abstract

The invention discloses a pleurotus geesteranus strain production method for increasing fruit body yield and total amino acid content with cobalt 60 radiation treatment. The method comprises the following process steps of: producing a stock spawn; producing a stock seed; and producing a cultivar by using the stock seed, and is characterized in that: the stock spawn is produced by the following steps of: preparing a material: preparing a stock spawn culture medium and putting the stock spawn culture medium into a test tube; purifying and rejuvenating from a pleurotus geesteranus fruit body to obtain a stock spawn, and inoculating stock spawn mycelia onto the stock spawn culture medium; and after a mycelia tube is full, and performing cobalt 60 radiation-induced breeding treatment for 30-60 minutes at the radiation dose of 0.4-0.6 KGY. Compared with the prior art, the method has the advantage that: the pleurotus geesteranus fruit body yield and the total content of various amino acids including total sulfur amino acid content, total branched-chain amino acid content, total child amino acid content, total necessary amino acid content, total flavor amino acid content, total sweet amino acid content and total amino acid content can be increased remarkably.

Description

(1) Technical field [0001] The present invention relates to a kind of cultivation technology of edible fungus, specifically a kind of production method of Pleurotus officinalis strain that utilizes cobalt 60 radiation treatment to improve fruit body yield and amino acid total amount (namely: a kind of using cobalt 60 ( 60 Co-gamma ray) irradiation treatment of Pleurotus officinalis strain production method). (two), background technology [0002] Xiuzhen mushroom (alias: small oyster mushroom, jiji mushroom, the shape of the mushroom is similar to Pteris edodes) is a kind of edible fungus in tropical and subtropical regions. It is native to India. The Xiuzhen mushroom in Fujian Province was introduced from Taiwan and gradually developed. Because of its small shape, white blanching, tender taste, delicious taste, rich nutrition, rich in protein, polysaccharides, crude fat, vitamins and trace mineral elements, Xiuzhen mushroom contains more than 17 kinds of amino acids, and wha...

In addition, cobalt-60 radioactive sources are widely used in almost all walks of life. In agriculture, they are often used in radiation breeding, stimulation of production, radiation control of insect pests, and food irradiation preservation and preservation. However, the use of cobalt-60 rays has not been seen Relevant reports on source radiation treatment of Pleurotus edodes strains
