The Effect of silver nanoparticle on lentil Seed Germination under drought stress
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 3
Abstract
A study was conducted to evaluate the effect s of silver nanoparticles for ameliorating negative effects of drought stress on germination and growth of lentil seeds. In order to investigate drought stress on lentil germination indices, an experiment was carried out in Iran from January to February 2015 at Ferdowsi University of Mashhad, in the biotechnology Laboratory, to create drought stress, poly ethylene glycol (PEG) at the levels of 0 (as control), -0.4,-0.6, -0.9 and -1.1 Mpa and Five levels of silver nanoparticles (0, 10, 20, 30 and 40 µg mL-1) on Lentil (Lens culinaris Medic); were tested. 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 that the effect of different concentrations of PEG and silver nanoparticles on germination rate and germination percentage, root length, root fresh and dry weight were significant. Silver nanoparticles increased germination percentage and rate over control. Length and fresh weight of radicle was greater in stressed seedlings. The results of this experiment showed that the use of AgNPs increased the germination in lentil under drought Levels.
