Effects of SiNP200 on the contents of CTK (A, E), GA3 (B, F), IAA (C, G) and ABA (D, H). (A–D) is wheat leaf sample; (E–H) is wheat stem sample. Values are means ± SE; n = 10. *, ** indicated that the significant difference between the control and SiNP200 treatment at p < 0.05 and p < 0.01, respectively (t-test)
