Figure. 1 The dissipation
dynamic curves of CLO, DFN and DFZ after application of exogenous SA in
nutrient solution. The dissipation
dynamic curves of CLO, DFN and DFZ in nutrient solution without SA
supplementation were shown in fig.1(A); the dissipation dynamic curves
of CLO in nutrient solution with SA supplementation were shown in
fig.1(B); the dissipation dynamic
curves of DFN in nutrient solution with SA supplementation were shown in
fig.1(C); the dissipation dynamic curves of DFZ in nutrient solution
with SA supplementation were shown in fig.1(D).
Figure. 2 The dynamic
distribution and accumulation of CLO, DFN and DFZ in roots, stems and
leaves of cucumber plants. The dynamic distribution and accumulation of
CLO, DFN and DFZ in roots, stems and leaves of cucumber plants without
SA supplementation were shown in fig.2(A); the dynamic distribution and
accumulation of CLO in roots, stems and leaves of cucumber plants with
SA supplementation were shown in fig.2(B); the dynamic distribution and
accumulation of DFN in roots, stems and leaves of cucumber plants with
SA supplementation were shown in fig.2(C); the dynamic distribution and
accumulation of DFZ in roots, stems and leaves of cucumber plants with
SA supplementation were shown in fig.2(D).
Figure. 3 The effects of exogenous SA on the mean
concentrations of pesticides in roots, stems and leaves of cucumber
plants 28-days of exposure. The effects of exogenous SA on the mean
concentrations of CLO in roots, stems and leaves of cucumber plants
28-days of exposure were shown in fig.3(A);
the effects of exogenous SA on the
mean concentrations of DFN in roots, stems and leaves of cucumber plants
28-days of exposure were shown in fig.3(B); the effects of exogenous SA
on the mean concentrations of DFZ in roots, stems and leaves of cucumber
plants 28-days of exposure were shown in fig.3(C).
Figure. 4 Effects of exogenous SA on fresh biomass (A),
chlorophyll content (B),
H2O2 content (C), proline content (D),
SOD activity (E), APX activity (F), GST activity (G)and MDA content
(H)of cucumber plants after roots exposure to
CLO (10mg L-1),
DFN (20mg L-1) and DFZ (10mg L-1),
respectively. Asterisks (*) indicate significant differences between the
control groups and the treatment groups without supplementing SA
(p< 0.05).
