摘要

铝胁迫下铝和其它元素的吸收、运输和分布是铝毒害的基础。采用土培法。研究荞麦（Fagopyrum esculentum Moench）在不同的铝浓度水平下对铝的吸收和运输，以及铝胁迫对氮、磷、钾、钙、镁、钠、锌、铜、铁、锰等元素的吸收和运输的影响。结果表明：在铝胁迫下，养麦植株铝含量迅速上升，而其他元素的吸收均受到一定的阻碍影响，在植株各部的含量均有所下降；花期荞麦与真叶期相比，地上部分的铝含量及根部含量均大幅下降，植株的其他元素含量同阳增加，表明铝胁迫得到缓解，可见养麦作为一种铝积累植物对铝毒有较强的适应能力。

Abstract

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.
