11种蝴蝶兰原生种在沈阳地区温室栽培适应性评价OA

To enrich the germplasm resource bank of Phalaenopsis in Shenyang and explore native germplasm materials suitable for cultivation in this region,11 native germplasm accessions of the genus Phalaenopsis Blume were introduced and subjected to a three-year acclimation and cultivation experiment in greenhouses in Shenyang.Phenotypic traits were systematically investigated,and a comprehensive evaluation system was es-tablished and quantitatively scored from three core dimensions:survival rate,flowering performance and growth vigor.The results showed that 9 out of the 11 introduced native germplasms could survive in Shenyang.Among them,Phalaenopsis pulcherrima and Phalaenopsis mannii exhibited the optimal comprehensive per-formance,which were the most suitable native germplasms for greenhouse cultivation in Shenyang.In con-trast,Phalaenopsis schilleriana and Phalaenopsis amabilis died completely during acclimation,with an adapta-bility grade rated as poor.Meanwhile,germplasms with outstanding single traits(such as multi-flower type,large-flower type and strong stress resistance)were specially marked,and their breeding utilization values were clarified.The findings provide a theoretical basis and practical reference for the introduction and acclima-tion,resource innovation and industrial application of native Phalaenopsis germplasm resources in Northeast China.
