Description

The role of silicon, boron and pH-dependent aluminium speciation in solution on aluminium toxicity in maize (Zea mays L.) Von dem Fachbereich Gartenbau der Universität Hannover zur Erlangung des akademischen Grades einer DOKTORIN DER GARTENBAUWISSENSCHAFTEN -Dr. rer. hort.- genehmigte Dissertation von MSc Yunxia Wang Geboren am 7. Februar 1974 in Jiangsu, China 2004 Referent: Prof. Dr. W. J. Horst Korreferent: Prof. Dr. H. P. Braun Tag der Promotion: 23. Juli 2004 ABSTRACT 3 ABSTRACT The toxic and inhibitive effects of aluminium (Al) on the growth and development of plants are well known, but the mechanisms of Al toxicity are not well understood, particularly the relative importance of symplastic versus apoplastic lesions of Al toxicity remains a matter of debate. In agricultural practice, rectifying Al toxicity needs convenient and economic methods. In addition to liming, organic manure or phosphorous fertilizer application, silicon (Si) and boron (B) supply were suggested to alleviate Al toxicity, but results are controversial, especially the possible mechanisms of Al/Si and Al/B interactions have not been conclusively examined.
