Potassium silicate as an inducer of abiotic stress resistance in grain sorghum seeds

Sorghum is an important crop that can absorb and accumulate abundant Si ranging, improving tissue toleranceto the water salt stress reducing sodium absorption. T hus, objective was to verify induction of resistance ingermination seedling growth sorghum seeds during germination due treatment with silicon.Two experiments were carried out two cultivars (EA03 EA955) solution potassium silicatesolutions at concentrations 0, 0.3, 0.6, 0.9 1.2 g L-1, in first experiment submitted usingPEG 6000 (0, -0.2, -0.4, -0.6 -0.8 MPa) second using NaCl 75, 150 225 mM). Wereanalysed, germination, count, shoot root length, ratio dry weight. The studiedgenotypes showed similar behavior when treated silicate. presence silicon whenexposed has no effect on but attenuates salinity damage related growth. Silicon attenuatesthe effects seeds, by maintaining up potential Mpa, providing betterroot development. However, silicate does not prevent caused high levels waterand stress, only attenuating its effects, thus, more studies are needed better clarify seeds.
