Abstract

Abstract: Using peony varieties Wulongpengsheng lateral buds as the explants, peony Wulongpengsheng adventitious buds were treated by LED light red, white, blue, green and yellow five kinds of light, to determine the number of adventitious bud, height, growth potential, callus, et al, and study the effects of different light quality on adventitious bud induction. The results showed that, the proliferation rate of peony adventitious bud induction was the highest under white light, and red light was better than other light quality in monochromatic light, with the proliferation rate of 695.05%. The influence of different light quality on adventitious bud height was red light >yellow light >green light > white light >blue light; The adventitious bud growth potential of peony under white light is better than other light qualities. Red and blue light promote callus growth. The effects of different light quality on the adventitious bud induction of peony were studied in order to provide data reference and theoretical basis for the peony tissue culture special LED light source research and development.

Key words: light quality, peony（Paeonia suffruticosa）, tissue culture, adventitious bud
