Sunflower is very sensitive to soil acidity and, in general, cannot tolerate Al saturation greater than 5%. Under these conditions, root growth is drastically affected reducing the ability of plants to explore larger soil volume, which consequently may block water and nutrient absorption. The aim of this study was to evaluate the tolerance of sunflower genotypes to four aluminum concentrations. An experiment was carried out at the Seed Laboratory of Embrapa Soja. Seeds of ten sunflower genotypes (Pioneer 6510, CF 101, Embrapa 122, BRS 323, BRS 322, V 70004, SYN 045, BRS G 32, HLA 211 CL and Catissol) were put directly on germination paper moistened with four doses of aluminum (0, 0.4, 0.8 and 1.2 mg dm-3 Al), using Al2(SO4)3.18H2O. Ten seeds were used for each treatment, with three replications. Rolls were placed in a growth chamber, in the dark and at a temperature of 25 ° C. Dry weight of roots was evaluated at seven days after. Dry weight of roots of sunflower genotypes was significantly affected by levels of aluminum in solution. Genotypes BRS 322, BRS 323 and BRS G 32 produced higher dry weight of roots, which was statistically superior to genotypes Catissol, Embrapa 122, SYN 045 and HLA 211 CL. The method is able to separate sunflower genotypes by development of roots under different concentrations of aluminum. |
