The effect of N-Sİ on tomato seed germination under salinity levels

Abstract

A study was conducted to evaluate the effects of Nano-Silicon (N-Si) for ameliorating negative effects of salinity on germination and growth of tomato seeds. N-Si at 2 concentrations (1 and 2 mM) and NaCl (1 and 2 mM) was studied on tomato seed germination. Germination characteristics such as germination percentage (GP), germination rate (GR), shoot and root of seedling length, fresh and dry weight of seedlings and mean germination time (MGT) were measured. Results showed the great effects of N-Si to improve salinity stress on tomato seed germination. One mM N-Si under 25 mM showed the great enhancement on germination characteristics such as germination rate, root length and dry weight. On the other hand, 2mM N-Si under 50 mM NaCl, results showed reduction on germination properties.
