Abstract:
The effects of phenolic acids on fast chlorophyll fluorescence transient and there parameters about the (Cerasus sachalinensis Kom.)were studied via plant efficiency analyzer from Hansatch PEA.In the rhizosphere soil of the northeast hill cherry seedlings，the different concentrations of the hydroxy benzoic acid (0.1，1.0，10.0 mmol?L-1)，coumarin (0.1，1.0，10.0 mmol?L-1)，hydroxy benzoic acid with coumarin (0.1，1.0，10.0 mmol?L-1) were applied into respectively.The results showed that there were different effects on chlorophyll fluorescence characteristics by different species and different concentrations of phenolic acid.Different concentration treatments of coumarin(B) had similar results as p-hydroxybenzoic acid+coumarin(AB)，present tendency of promotion in low concentration and inhibition in high concentration that was 0.1B(AB)>1.0B(AB)>CK>10B(AB).But the results of effects of p-hydroxybenzoic was inhibition，and the inhibition weakened with the increase of concentration,CK>1.0A>10A>0.1A.In addition，the experimental data showed that the number of active reaction centers of PSⅡ changed significantly after treated by phenolic acids.So,phenolic acids might change the photosynthesis of northeast hill cherry by changing the number of active reaction centers of PSⅡ.
