摘要:用灰色系统理论分析研锎添加栽培的巴两蘑菇子实体中17种氨基酸含量与重金属镉含量的关系,旨在为今后低镉巴而蘑
菇的栽培提供科学依据。结果表明,在钢复合作用下巴西蘑菇子实体中的17种氨基酸中,组氨酸含量与重金属镉含量的关联度
最大,为0.79。关联度越大,相似程度就越高,说明硒复合作用下巴西菇子实体中17种氨基酸中组氨酸含量与重金属镉含量的
关系最为密切。其次是苏氨酸含最与重镉含量的关联度,第三是胱氨酸含量与重金属镉含量的关联度,最小是甲硫氨酸含量与金属
镉含量的关联度。各处理的关联度及排序为B>B>B>Bo>B2,其中B,处理的关联度最大,为087,B2处理的关联度最小,为0.56说
明硒钢浓度对巴西蘑菇子实体镉含量与各氨基酸含量具有一定影响。

Abstract: The grey s stem theory was employed to analyze the relationships of 17 amino acids content and Cd content of A garicus brasili
