Silicon Application Induced Alleviation of Aluminum Toxicity in Xaraés Palisadegrass

Aluminum (Al) toxicity is a major abiotic constraint for agricultural production in acidic soils that needs sustainable solution to deal with plant tolerance. Silicon (Si) plays important roles alleviating the harmful effects of Al plants. The genus Urochloa includes most grasses and hybrids, it currently used as pastures tropical regions. Xaraés palisadegrass (Urochloa brizantha cv. Xaraés) forage relatively tolerant under field-grown conditions, which might be explained by great uptake accumulation Si. However, studies are needed access benefits Si application alleviate on nutritional status, production, chemical–bromatological composition. study was conducted greenhouse conditions effect five concentrations evaluated (0, 0.3, 0.6, 1.2, 2.4 mM) well nutrient solutions containing 1 mM two sampling dates (two cuts). following evaluations were performed: number tillers leaves, shoot biomass, N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, Zn, Al, concentration leaf tissue, root neutral detergent fiber (NDF), acid (ADF) content shoot. supply affected relation between increasing detriment transport thereby palisadegrass. 1.4 1.6 decreased roots shoots translocation 259% (from 3.26 1.26%), contributed higher leaves per plot led greater dry mass without affecting tillering. could considered one greatest accumulator plants above 4.7% mass.
