Abstract
The effect that UV-B and different concentrations of ABA treatments on winter wheat seedling was studied,and we evaluated the enhanced UV-B resistance of winter wheat seedling.To explore whether there is interaction of ABA and UV-B.The winter wheat of 120 was used in the experiment,the seedling were treated with concentrations of 0.1、1.0、5.0 and 10.0 μmol · L-1 of ABA and intensity of 20μW · cm-2 UV-B.And then related indexes of plant height,dry weight,fluorescence,leaf colour,relative electrical conductivity,MDA and flavonoids were all determined.The results showed that UV-B treatment inhibited the plant height,leaf colour,dry weight,F0 and Fv/Fm,but improved MDA,flavonoids and relative electric conductivity.After ABA treatment,With the concentration of ABA increasing,the dry weight,Fv/Fm and leaf colour were increased at first and then Marreased.When the concentration of ABA was 1 μM,they reached maximum.UV-B and ABA treatment inhibited the plant height,dry weight,Fv/Fm and leaf colour,but the extent of inhibition ratio was reduced than UV-B treatment.
