Establishment of a High-Temperature Tolerance Evaluation System for the Filaments of Pyropia yezoensis
摘要
Abstract
To address the lack of standardized methods for evaluating the high-temperature tolerance of Pyropia yezoensis conchocelis,this study established a scientific evaluation model.Growth parameters,including main branch length(MBL),secondary branch length(SBL),number of main branch(NMB),number of lateral branches(NLB),and conchocelis area(CA),were measured in 95 strains under optimal(20℃)and high-temperature(25℃)conditions.Using heat tolerance coefficients,membership function values,entropy weighting,and cluster analysis,we found significant correlations among these traits,with MBL,SBL,and NLB exhibiting weights exceeding 20%.A multiple linear re-gression model was constructed to predict the comprehensive evaluation index(D):Di=0.173×KNLB,i+0.146×KSBL,i+0.112×SCA,i+0.181×KNMB,i+0.115×KMBL,i,The model identified NLB,SBL,CA,and NMB as key indicators for assessing high-temperature tolerance,providing a reliable tool for screen-ing heat-resistant strains in P.yezoensis cultivation.关键词
