摘　　要：为筛选出耐涝性强的花椒种质资源材料,通过人工淹水试验,对四川省植物工程研究院前期优选出的6种花椒种质材料的生长量和涝害情况等进行了综合评价。结果表明:川植-3在涝渍胁迫下,仍维持较大的株高、基径生长量胁迫指数,并且在涝渍胁迫至66 h时才出现涝害症状,涝害指数仅为5.56%,涝渍胁迫至96 h时其涝害指数为55.56%,各处理平均涝害指数仅为9.63%,受害症状远轻于参试的花椒(种)和竹叶花椒(种)材料,耐涝性最强。In order to screen out strong waterlogging tolerance germplasm resources of Zanthoxylum bungeanum,the growth and waterlogging damage of six Z.bungeanum germplasm materials selected by Sichuan academy of botanical engineering in the early stage were comprehensively evaluated through artificial flooding experiment.The results showed that under waterlogging stress,Chuanzhi-3 still maintained a large stress index of plant height and basal diameter growth,and the waterlogging symptoms appeared only after waterlogging stress for 66 h,with a waterlogging index of only 5.56%,and after waterlogging stress for 96 h,the waterlogging index was 55.56%.The average waterlogging index of each treatment was only 9.63%.The waterlogging symptoms of Chuanzhi-3 were much lighter than other materials,and the waterlogging tolerance was the strongest.
