Effect of nanosilver particles on germination traits of Taverniera cuneifolia L. under salinity stress

In order this study the effect of Nano Silver on the growth of Taverniera cuneifolia under salinity stress conditions, an experiment was carried out as factorial based on laboratory conditions (germinator) in summer 2014 on complete randomized design with four replications. Nanosilver particles treatments with 4 levels (0, 30, 80 and 120 mg/l) and salinity treatments (0, 50, 100 and 200 mM) include sodium of salts (NaCl) was considered. Germinated seeds two times in everyday for 30 days in laboratory were counted. Then measured seed germination traits including (radicle length, shoot length, seedling length, seed vigor index, germination percent, germination rate, average time of germination, root fresh weight, root dry weight, plumule fresh weight, plumule dry weight). The results showed that effects of different levels of nano-priming caused significant differences for all traits at one percentage and fresh weight of shoot and radicle at five percent. Also treatment of sodium chloride (salt) also caused a significant difference for all of the traits except germination rate and average time of germination was at the level of one percent. The interaction of nano-priming treatments and sodium chloride also caused difference significant in the percentage of germination, vigor index, length of plumule and radicle and root dry weight. The general result is that concentrations of 30 and 80 mg/l of nanosilver particles had a positive effect on most of the seed germination traits of Taverniera cuneifolia at different levels of salinity stress.
