Impacts of nano-TiO2 on the initial development stages of barley seedlings under salinity

The most important development period in cereal plants is the initial stage, that is, seed germination and early seedling development. Even if barley thought to be a partially salt-tolerant plant, it may severely affected when exposed salinity at developmental periods. Pre-treatment preparation of seeds before sowing have an agriculture. Nano-seed priming treatment new approach used increase germination, emergence growth recently. In this study, effects nano-TiO2 (0, 100, 200 mg L-1 n-TiO2) pre-application ongoing/combination application under 200, 300 mM NaCl) on were investigated. Root lengths (RL, mm), rates (GR, %), radicle emerging (RE, number coleoptiles (CN) measured depending day (1, 2, 3 days). At end third day, fresh dry weights (FW,DW mg) measured. relative index (RGI) root mean time (MGT) calculated. It was determined 100 n-TiO2 increased length RGI compared control groups. observed significantly percentage, biomass especially salt conditions. Also, RE too conditions (1st day). NaCl inhibitory dose, also remained below 20% all groups
