Abstract:
It is well known that the important role of citrate in the mechanism for Al resistance in soybean.The effect of aluminum plus exogenous citrate acid on fluorescence detection,aluminum comparative concentration of soybean root tips and aluminum speciation in treated solution,were all investigated using hydroponic culture,to discover the effect of citrate with aluminum which exists in the rhizosphere of soybean and the mechanism of alleviating aluminum toxicity by soybean root exudation.Results showed it was significant that aluminum accumulated in the cell wall of soybean root tip cells,and it became more and more remarkable with dose and time increased;in the present of exogenous citric acid,the content of aluminum accumulated in the cell wall decreased,especially in Zhechun No.3.The change of comparative Al content in root tips of Zhechun No.3 and Zhechun No.2 did not play the same pattern in dose-and time-dependent manner.From the analysis of aluminum speciation,it could be seen that the change pattern of the content of Alaand Alb were parallel;the content of the two form decreased but Alcincreased with exogenous organic acids.Thus it could be concluded that it needs time and displayed as fluctuating periodically in the mechanism of detoxification aluminum,when plants meet aluminum for the initial stages.Exogenous citric acid was more effective to Zhechun No.3 than to Zhechun No.2 under aluminum stress.At the same time,only proper proportion of exogenous citric acid could avail to detoxification of aluminum for soybean;Yet it may result in the fact of serious toxicity on plants overstep some extent of exogenous citric acid.
