Objective] To research the activity changes of several enzymes during florescence in petals of Lonicera japonica Thunb.[Method] With flowers of L.japonica in different flowering phases as the test materials, we researched the changes of soluble protein content, MDA con-tent, SOD activity and POD activity during the flowering of L.japonica.[ Result] During the flowering process, SOD activity and POD activity declined as the soluble protein content reduced.From silver flower period to golden flower period, MDA content increased gradually as the flower color changed.[Conclusion] This research provides scientific references for the physiological mechanism of the flower color change of L.japoni-ca.
