Abstract:
Straw mushroom ‘V106’ was used as the test material and stable and efficient aerospace mutagenesis was applied to treat strain ‘V106’.The effects of aerospace mutagenesis on the biological characteristics of the mutant strain,including mycelial and substrate growth,intracellular and extracellular active substance content and storage characteristics of fresh mushrooms were studied,in order to provide new ideas for mutation breeding of Volvariella volvacea.The results showed that seven mutagenic strains were screened and their biological characteristics were changed to various degrees.Among them,the mycelial growth rate of mutant strain T7 was increased by 9.42%,the emergence time was reduced to 13 days,the mushroom quality was increased by 1.37%,the contents of intracellular ergothioin,total intracellular and extracellular phenols and extracellular flavonoids were better than those of ‘V106’,and the shelf life was extended to 4 days.The successful screening of strain T7 showed that space mutation can be used as an effective way for the breeding of Volvariella volvacea and promoted the positive development of Volvariella volvacea industry.
