摘要:
为了筛选出适合徐州地区的Cd耐性小麦品种，通过室内培养法对徐州市主栽的14种小麦种子在40 mg?L-1（Cd）胁迫下小麦发芽势、发芽率、胚根长、胚芽长、胚根鲜重及胚芽鲜重等生理指标的分析，探讨不同小麦品种萌发期对镉胁迫的耐性机制。结果表明：不同品种小麦对Cd胁迫的耐性不同，总体小麦发芽势的影响大于发芽率，小麦胚根长度对镉的耐性最弱。聚类分析可将14个小麦品种划分为镉胁迫抑制型（百农AK58和新麦208）、中间型（迁麦1号、新麦288、豫农35及金禾9123）和耐受型（徐麦30、徐麦33、保麦5号、保麦2号、烟农19、百农207、淮麦20和淮麦35）。
Abstract:
In order to select the Cd tolerant wheat varieties suitable for Xuzhou area,the effects of 40 mg?L-1 cadmium stress on the germination vigor,germination rate,radicle length,plantule length,the fresh weight of radicle and plantule of wheat varieties were analyzed by indoor cultivation experiment,dan the tolerance responds on cadmium stress in the main 14 popularized wheat varieties of Xuzhou city were investigated.The results showed that the tolerance of different wheat varieties to Cd stress was different,and the effect of Cd stress on germination vigor of wheat was greater than that of germination rate.The radicle length of wheat had the weakest tolerant to cadmium stress.Cluster analysis of the composite index in grains showed that the 14 wheat varieties could be sorted into three groups.BainongAK58 and Xinmai208 were in the group of inhibitory type of Cd stress.Qianmai1,Xinmai288,Yunong35 and Jinhe9123 were in the group of midium-inhibitory type. Xumai30 ,Xumai33, Baomai5, Baomai2, Yannong19, Bainong207,Huaimai20 and Huaimai35 were in the group of tolerant type.
