The study of the effects of nano silver technology on salinity tolerance of cumin seed (Cuminum cyminum L.)

In this research the effects of nano-silver particles on salinity tolerance behaviors of germination stages of Cuminum cyminum L., one invitro experiments were conducted factorially based on CRD with four replicates during autumn 2008. The nano-silver particles treatments and salinity concentration levels consisted of: 0, 20, 40, 60, 80 and 100 mg.kg-1 and 0, 30, 60, 90,120,150,180 mmol.l-1 respectively. For germination test, after treating by solutions, the disinfected seeds were placed on wattman paper in Petri-dish, and located inside the germinator with 20°C. The numbers of germinated seeds were recorded twice a daily, in a 14 days period. Then the germination percentage, germination speed and vigor, were determined. Results showed that the 20 mg.kg-1 of nano-silver particles had the best effect on vigor, germination percentage and speed, fresh weight and the length of rootlet in germinator condition. There were significant differences in salinity treatments. In addition, the treated seeds with 20 mg.kg-1of nano-silver particles showed the highest concentrations of germination percentage, germination speed, vigor of stem in greenhouse condition.
