Abstract:
The Orychophragmus violaceus adventitious buds produced in tissue culture were used as propagules,the sodium alginate added nano TiO2 was made into artificial seed coat.The effect of different concentration of nano TiO2 on artificial seeds germination and antibacterial ability was observed,the differences between nano TiO2 with NAA or carbendazim and the interactions of them were studied.The results showed that nano TiO2 had the similar auxin action with NAA,and significantly increased the germinaton and rooting rate,and the two had a synergistic effect.Combination 0.1 mg?L-1 NAA+30 g?L-1 TiO2+1/2MS+3% sucrose under sterile conditions made Orychophragmus violaceus artificial seeds’ germination rate reached 100% and rooting rate reached 80%,was the best combination;the experimental group added 30 g?L-1 nano TiO2 under natural conditions made contamination rate reached 5.6%,germination rate reached 83.33%,was the best combination.The experimental group containing both nano TiO2 and carbendazim significantly reduced the germination rate and antibacterial ability.
