烯效唑对盐胁迫下刺槐生理特性的影响OA

The test studied the effect of physiological characteristics of Robinia pseudoacacia L.under salt stress.The 1-year-old Robinia pseudoacacia L.was applied as the test material,and then two salt stress concentrations of 2 g·L-1 and 4 g·L-1 were set,and set two concentrations of unicon-azole of 55 mg·L-1 and 80 mg·L-1 were applied.Each treatment was repeated three times.The re-sults showed that O2-and H2O2 contents of Robinia pseudoacacia L.in salt stress treatment was sig-nificantly higher than control,and the uniconazole treatment was significantly lower than the two salt concentrations treatments;the activities of POD,CAT,APX,and GR of Robinia pseudoacacia L.in the two concentrations of salt stress treatments were significantly higher than control,and the activi-ties of four antioxidant enzymes in uniconazole treatment were significantly higher than salt stress treatments.Under the same salt concentration conditions,the effects of the two uniconazole concen-trations on the activities of the four enzymes were at the same level.According to the comprehensive analysis,the suitable concentration of uniconazole to alleviate the salt stress of Robinia pseudoacacia L.is 55 mg·L-1.
