Figure 11

Effects of SiO 2 NPs concentrations on ABA and IAA hormone concentrations in the roots of non-transgenic and Bt-transgenic cottons. The value were given as means ± SD. The (*) was represented significant difference (p <0.05) between control and SiO2 NPs treatments at the same cotton, and the (*) above the line segment was represented significant difference (p <0.05) between cultivars at the same SiO2 NPs concentration.
