| Title : | IMPACT OF SILICON DIOXIDE NANOPARTICLES ON SEEDLING EARLY GROWTH OF LENTIL (LENS CULINARIS MEDIK.) GENOTYPES WITH VARIOUS ORIGINS |
| Abstract : | Quick seed germination and stand establishment are significant factors to lentil production under saline soil of arid and semi-arid regions. The application of beneficial nanoparticles during the seed germination has shown a new field of nano-agriculture. The current study was aimed at investigating the potential influences of nano-silicon dioxide (at 1 and 2 mM concentration) on seed germination of lentil (Lens culinaris Medik.) genotypes with different geographical origins under a range of NaCl concentrations (i.e. 0, 50, 100 and 150 mM). Results showed that germination significantly delayed by increasing salt stress. However, the rate of decline was variable among the genotypes. Application of 1 mM silicon dioxide nanoparticles (nSiO2) could considerably alleviate the adverse effect of salt stress on germination percentage, root and shoot length, seedling weight, mean germination time, seedling vigour index and cotyledon reserve mobilization. The suppressive impact with higher nSiO2 concentration (2 Mm) shows the need for cautious application of these particles during seed germination. The best performance was recorded for genotypes originated from Mexico, Syria and Jordan (PI 299127, Syrian Local Large, 78S 26013). Our results suggest that nSiO2 has favorable effect on lentil seed germination under salinity stress and it can be economic to use suitable concentration of this nanoparticle in the production system under saline conditions. |
