Table 1. Numbers of S. avenae in the control and the
treatments at different concentrations of Nano-Se. Data were compared
statistically by one-way analysis of variance (ANOVA) and least
significant difference (LSD) and Levene test in SPSS 26.0. Different
letters in each row indicate the significant difference atp<0.05 .
Figure 1. S. avenae number in control and different
concentrations of Nano-Se. Different letters indicate a significant
difference at p<0.05 .
Figure 2. Effects of Nano-Se application on JA(A), SA(B),
MT(C), and DIMBOA(D) contents in wheat seedlings. Different letters
indicate a significant difference at p<0.05 .
Figure 3. Effects of nano-Se application on CAT(A), POD(B),
SOD(C), LOX(D), GSH-Px(E), VE(F), APX(G), MDA(H), GSH(I), Pro(J), and
LPO(K) contents in wheat seedlings. Different letters in one figure
indicate a significant difference at p<0.05.
Figure 4. Effects of nano-Se application on the concentration
of flavone compounds (A) and phenolic acids (B) in wheat seedlings.
Different letters in a figure indicate a significant difference atp<0.05 .
Figure 5. Effects of applied nano-Se (5 mg/L), MT (10 mg/L) and
their combination on S. avenae number (A), DIMBOA, MT, JA, and SA
contents (B), and related synthesis genes (C) in wheat seedlings.
Different letters among treatments indicate a significant difference atp<0.05 .
Figure 6. Fingerprint similarity analysis (A), GC-IMS
three-dimensional spectrum (B), top view (C), and gas phase ion
migration spectroscopy(D) of metabolites for all treatment in wheat
seedlings with aphid infection.
Figure 7. Qualitative analysis (A) and gallery plot (B) of
volatile organic compounds measured in wheat seedlings. The changes in
the concentration of differential metabolites in wheat seedlings exposed
to nano-Se (5 mg/L), melatonin (10 mg/L), and their combination (C).
Different letters among treatments indicate a significant difference atp<0.05 .
Figure 8. Proposed mechanism of nano-Se improving the secondary
metabolism in wheat seedlings and against Sitobion avenaeinfection.
