| 英文摘要: |
| Triazoles have been characterized as broad-spectr
um fungicides and plant growth regulators in agriculture. This experiment was co
nducted to evaluate the functional features of the complex of hexaconazole with
copper acetate. The results indicated that the hexaconazole Cu complex displaye
d a superior antimicrobial capability to that of original hexaconazole. The inhi
bition zone diameters of 0.05 mmol·L-1 hexaconazole-Cu complex were 1.48
times la
rger than that of hexaconazole. The complex also changed the physiological envir
onment of wheat seedlings, which contributed to lower the plant height and incre
ase the root/shoot ratio. After being treated with 0.03 mmol·L-1 hexacona
zole-Cu
complex, the activity of SOD and POD and the concentration of GSH and chlorophyl
l in wheat seedlings increased by 24.65%, 61.06%, 30.41% and 59.04% respecti
vely, compared to those of the control. In addition, the accumulation of MDA was
restrained in wheat seedlings, and the concentration of MDA decreased by 26.67%
under the complex treatment compared to hexaconazole. |
