Abstract
Uptake characters of different copper forms by young maize plant underwent treatments with either Fe deficiency or sufficiency were studied by hydroponic culture.Furthermore,we studied effects on Fe uptake by young plant of maize under different concentrations and different forms of Cu.The results showed that,Cu contents in the plant were higher with increasing Cu concentration under Fe deficiency treatment,and the contents of Cu in roots were notably higher than shoots.Inorganic Cu was the easiest uptake by young plant of maize,and most of Cu contents were transferred to shoots.Among the five different Cu forms treatments,the contents of Cu were in the lowest in young maize plant,but the relative contents of Cu by transferred to shoots were in the highest under EDTA-Cu treatment.The total Cu contents were in the highest by the plant assimilated under five different organic complex Cu treatments than inorganic Cu treatment,and they all were accumulated in roots,but the transfer proportion to shoots were lower.Increasing ion could visibly decrease Cu contents in the plant,and more Cu contents stayed in roots,but less was transferred to shoots,so organic complex Cu could decrease phyto-toxicity to young maize plant.Inorganic Fe exhibited the biggest inhibiting effect on Cu contents by young maize plant assimilated,and subsequently was tartrateCu,malate-Cu,citrate-Cu,oxalateCu,and EDTA-Cu had the smallest inhibiting effect on Cu contents.
