具有杀虫剂抗性的平菇种质资源筛选
Screening of Pleurotus ostreatus Germplasm Resources with Insecticide Resistance
摘要
Abstract
To screen the Pleurotus spp.germplasm resources that were resistant to the highly effective beta-cypermethrin(β-CP),through plate inhibition tests,2 application methods(dressing the sub-strate and spraying)were used to systematically evaluate the mycelial growth,fruiting body yield,pesticide residues and nutritional quality of 14 Pleurotus spp.strains.The results showed that there were significant differences in the resistance of the 14 strains to β-CP,with the mycelial inhibition rate ranging from 25.33％to 73.53％.Adding β-CP to the substrate significantly inhibited mycelial growth and fruiting body yield,but the impact of spraying on yield was less than that of dressing the sub-strate.High-pressure sterilization and mycelial growth could significantly degrade β-CP in the sub-strate,and the β-CP residues in the fruiting bodies of both application methods were lower than the national standard limit,and the residues in the high-antibiotic strains were even lower.The effects of β-CP on crude protein,polysaccharides and ash content were related to the strain and application method.Strain XK101 performed best when β-CP was applied,possessing good resistance potential and production stability and could be used as an excellent germplasm resource for resistance breeding and safe production.关键词
