The effects CaO nanoparticles applications on Onobrycis sativa seedlings growth under mannitol stress

Abstract

In our study, two Onobrycis sativa population (Uzuntekne, and Barış) were used as the material for the response to CaO -NPs nanoparticulate. More DNSA and proline were collected in these two Onobrycis sativa genotypes than in control seedlings while two genotypes were exposed to mannitol. Proline content highest at 150 mM mannitol and 1.5 ppm CaO while the minimum and maximum content was observed at 50–150 mM mannitol dosages. The collected of DNSA was greatly correlated with higher mannitol concentrations. Proline activities demonstrated an increasing trend against the increasing concentration of mannitol. In conclusion, the growth characteristics and physiological responses of Onobrycis sativa increased, depending on genotype, mannitol and CaO dosage in the media and their interactions.
