Kuntze] plants were cultivated hydroponically and treated with adequate (control) or low B supply (-B) without or with 300 μM Al (-B+Al) for 14 weeks. However, the addition of Al to the nutrient solution reduced Mg uptake in the shoots to about 30% of that in the Al 0 treatments, while there was a net loss of Mg in the roots in spite of the fact that dry matter increased. The symptoms of aluminium toxicity are not easily identifiable. endstream endobj 249 0 obj <>/Metadata 17 0 R/Pages 246 0 R/StructTreeRoot 28 0 R/Type/Catalog>> endobj 250 0 obj <>/MediaBox[0 0 612 792]/Parent 246 0 R/Resources<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI]/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 251 0 obj <>stream Was magnesium deficiency induced as a result of the plants attempt to overcome aluminium toxicity?

Zinc is necessary for cell elongation, cell elasticity. Early induction of Fe-SOD gene expression is involved in tolerance to Mn toxicity in perennial ryegrass.

In addition to oxygen, carbon dioxide and water, plants require at least 14 mineral elements for adequate nutrition (Marschner, 1995; Mengel et al., 2001). These ionic forms of Al have been shown to be very toxic to plants, initially causing inhibition of root elongation by destroying the cell structure of the root apex and thus affecting water and nutrient uptake by the roots; as a consequence, plant growth and development is seriously hindered. Aluminium has the following affects on plants: Roots - aluminium decreases the amount of roots a plant produces and it also reduces the function of roots that are produced. Interpreting visual nutrient deficiency and toxicity symptoms in plants can be difficult and plant analysis or soil testing Background As discussed in Nutrient Management Module 2, Plant Nutrition and Soil Fertility (NM 2), growth.

Aluminum (Al) toxicity and phosphorous (P) deficiency are two major limiting factors for plant growth on acidic soils. Even though the Al-P interaction has been widely investigated, the impact of P-nutrition on Al-toxicity still remains controversial and poorly understood.
