【摘要】 采用室内培养实验方法,对用于土壤中重金属生物有效性测定的黑麦的替代植物进行了研究,结果表明,小麦由于结果和黑麦比较接近,而且种子易于得到,因此是黑麦的较佳替代植物。经试验小麦幼苗的生长期为14d。更多还原

【Abstract】 It has been recognized that determination of heavy metal bioavailability (HMB) in soil is of academically importance. The rye seedling method has more advantages in determination of HMB compared with other procedures at present. The present study using wheat seedling rather than rye was done, because utilization of rye as test material has been recognized as some limitation. The results showed that wheat seedling was an ideal substituted plant of rye, as the plant exhibited an absorbing ability on 5 heavy metals similar to rye, and the seed was easier to be gained than others; and the growth period was as long as 14 days.更多还原
