Resumo

Silicon is considered a beneficial element for several plants, especially in crops with potential for residual biodiesel, and can provide an increase in dry matter in oilseeds. The objective of this work was to evaluate the accumulative power of silicon on sunflower germination and its development when submitted to different doses. Sunflower seeds cv. Multissol were sown in polypropylene trays in substrate incorporated at different concentrations of organic silicon, in treatments: T1 - control; T2 - 5.0; T3 - 10.0; T4 - 15.0 and T5 – 20.0 g kg-1 (BioMarkan®, 90% SiO2), totaling 128 repetitions per treatment. The germination percentage was evaluated in five periods (3rd, 6th, 9th, 12th and 15th day). On the 20th day, the seedlings were evaluated in terms of: number of leaves, shoot length, stem diameter, total fresh and dry mass. Subsequently, the analysis of chemical concentration of silicon in the seedlings and X-ray microanalysis in the leaves of the sunflower seedlings were carried out. The interaction between treatments and germination days was significant for the days in which germination was higher on the 6th day. The silicon incorporated into the substrate accelerates the germination of sunflower seeds cv. Multissol. The sunflower cv. Multissol is a silicon accumulator and improves development up to a concentration of 10 g kg-1 of silicon.
