The mechanism by which aluminum interferes with ion influx and translocation is the basic of Al toxicity to plants

but it is not well known.In this study

the effects of different aluminum levels on the influx and translocation of the cations i.e.calcium

potassium

magnesium

sodium

zinc

copper

iron

manganese

total nitrogen and total phosphorus were measured in barley(Fagopyrum esculentum Moench).The results revealed that as the aluminum concentration in vitro increased

the Al content in plant increased greatly

and the other element contents decreased correspondingly.Comparing with the vegetative stage

the Al contents in shoot and root decreased a lot in the flowering stage

and the contents of other essential elements also increased

indicating Al toxicity can be alleviated in buckwheat at this stage.This showed as an Al tolerant plant

buckwheat owns a relatively great adaptability to Al toxicity.
