不同水稻种质资源对镉的吸收富集特征分析
Analysis of Cadmium Absorption and Enrichment Characteristics of Different Rice Resource Materials
摘要
Abstract
This study selected 37 different types of rice germplasm resources,cultivated them in slightly acidic soil with excessive cadmium content,and measured the cadmium levels in their roots,stems,leaves,and brown rice.The differences and correlations in cadmium content among different rice types and various parts of the same type were analyzed,and the absorption and translocation characteristics of cadmium among different rice germplasm resources were compared.The results showed that among different types,sterile lines exhibited the strongest absorption capacity for soil Cd,while varieties demonstrated the highest translocation ability for Cd.For different parts of the same type,the Cd content followed the order:root＞stem＞leaf＞brown rice.Taoxiangyoumeizhen,Yixiangyou 45,and Taoxiangyou 188 exhibited higher root-stem translocation coefficients,making them suitable for cultivation in soils with lower cadmium content.Shensiyou 16 and Nanchuannuodao showed significantly lower root-stem translocation coefficients compared to other varieties,qualifying them as low-cadmium-accumulating cultivars for local promotion.A total of 14 materials displayed stem-brown rice translocation coefficients lower than the control,among which Wanyou 80,H608,H601,and Wanhui 90 had notably lower translocation coefficients than other materials,serving as core resources for breeding low-cadmium-accumulating rice varieties.关键词
