摘要
本试验以薄荷试管苗叶片为外植体,
研究了激素、光照、褐变抑制剂对不定芽诱导的影响,进而筛选出合适的生根培养基。研究结果表明:
薄荷叶片最佳不定芽诱导的培养基为MS +1.4mg /L TDZ +0.2mg /L NAA +30g /L 蔗糖+5.5g /L 琼脂,诱导率达27.78%;暗培养20d 后再转接一次,叶片不定芽诱导率提高至64.29%,褐化率低至11.90%;最佳生根培养基为MS +0.1mg /L NAA +20g /L 蔗糖+5.5g /L 琼脂,生根率达97.50%;再生苗经生根、炼苗后移栽,植株成活率达100%。本试验建立了薄荷叶片离体再生体系,为薄荷无菌苗生产和遗传转化研究提供了技术支撑。

Abstract Leaves of tube Mentha were ud to study the effects of different plant growth regulators,light condition and anti-browning treatments on adventitious bud induction,and the appropriate rooting medium was further lected.The results showed that:The best culture medium f
or adventitious bud induction was MS +1.4mg /L TDZ +0.2mg /L NAA +30g /L sugar +5.5g /L agar,and the induction rate was 27.78%;When Mentha leaves cultured for 20days under dark condition,adventitious bud induction rate reached 64.29%and the browning rate reduced to 11.90%;The rooting rate reached 97.50%when adventitious bud were cultured on MS medium with 0.1mg /L NAA,30g /L sugar and 5.5g /L agar;And the survival rate of adventitious bud was 100%after being transplanted.Regeneration system of mentha had been established,which provided technical support for aptic edlings production and theoretical for the genetic transformation of Mentha.

基金项目:本研究由安徽科技学院自然科学基金项目(ZRC2016490)和安徽科技学院重点建设学科(AKZDXK2015C05)共同资助薄荷(Mentha haplocalyx Briq)为唇形科薄荷属的
一种多年生草本植物(中国科学院中国植物志编委
会,2010),又名水薄荷、升阳草、人丹草等,全株具有
浓重的清爽香味,其地上部分干燥后可以入药,是我
国重要的中草药和香料植物。薄荷药用价值高,具有
疏散风热、清利头目、醒胃开脾,疏肝行气等功能(中
国药典,一部,2010),从薄荷属植物中提取加工得到
愁的反义词的薄荷油、薄荷脑、留兰香,可以用于食品、医药、香
烟、香料、化妆品等领域(周露和谢文申,2012)。目前有关薄荷的研究多集中在化学成分的检测(徐凌玉等,2013;颜永刚等,2011)和遗传多样性分析(梁呈元等,2011,中药材,34(8):1190-1193;房海灵等,2010)等方面,关于薄荷叶片离体再生体系的建立方面的研究尚未见报道,在植物转基因研究中叶盘法是使用较为广泛的有效方法之一,而离体再生体系的建立是实现遗传转化的前提(Wedzony M.,et al.,2014),因此探讨薄荷叶片再生体系的建立不仅可用于诱变育种,对后续的遗传转化研究也具有重要意义。
