Screening and Evaluation of Lentinula edodes Strains Suitable for Cultivation With Mulberry Branches Added to Substrate
摘要
Abstract
Taking mulberry branches as an alternative substrate,five strains('HuxiangF6''Shenxiang1513''Qiuzai3''Xiang0912''Chuxiang101')were cultivated with substrates containing 0％,20％,and 80％mulberry branches.Parameters including mycelial growth rate,yield,conversion rate,and agronomic traits of fruiting bodies were measured,and grey relational analysis was applied to comprehensively evaluate the adaptability of each strain to the mulberry branch-based substrates,to screen Lentinula edodes strains suitable for cultivation,in order to provide reference for the resource utilization of mulberry branches.The results showed that mycelial growth was optimal at the 20％mulberry branch level,with'Shenxiang1513'exhibiting the highest growth rate((2.73±0.28)mm·d-1).At the 80％mulberry branch level,mycelial growth was significantly inhibited,with rates ranging from(1.86±0.04)mm·d-1 to(2.08±0.18)mm·d-1.The highest dry yield per bag was achieved with 20％mulberry branches,where'Shenxiang1513'reached(149.3±9.6)g,while the best conversion rate was observed at the 80％level,with'Shenxiang1513'and'Qiuzai3'attaining 11.8％and 11.6％,respectively.Regarding the agronomic traits of the second-flush fruiting bodies,'Shenxiang1513'cultivated with 20％mulberry branches showed superior performance in individual fresh weight((42.7±3.5)g),pileus diameter((73.1±6.1)mm),and pileus proportion(85.94％±3.70％).Grey relational analysis indicated that under 0％and 20％mulberry branch conditions,'Shenxiang1513'had the highest relational coefficients(weighted 0.774 and 0.696;equal-weight 0.767 and 0.688,respectively),identifying it as the optimal strain.Under 80％mulberry branch conditions,'Qiuzai3'exhibited the highest coefficients(weighted 0.683;equal-weight 0.677),making it the most suitable strain.关键词
