摘要: 试验以牡丹(Paeonia suffruticosa)品种乌龙捧盛的侧芽作为外植体,用LED光源红、白、蓝、绿和黄光5种光质对牡丹乌龙捧盛不定芽进行光照处理,测定其不定芽数量、高度、生长势、愈伤情况等,研究不同光质对其不定芽诱导的影响。结果表明,牡丹不定芽诱导在白光下增殖率最高,单色光中,红光优于其他光质,增殖率为695.05%;不同光质对不定芽高度影响为红光>黄光>绿光>白光>蓝光;牡丹在白光下不定芽生长势优于其他光质;而红光、蓝光对愈伤组织的生长有促进作用。通过不同光质对牡丹乌龙捧盛不定芽诱导的影响研究,以期为牡丹组织培养专用LED光源的研发提供数据参考和理论依据。

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
