摘要

非洲菊(Gerbera jamesonii Bolus ex Hook)。f;菊科植物(Asteraceae)，因其独特的观赏价值而成为经济上最重要的观赏植物之一。本研究建立了非洲菊‘粉红旋律’优质种材规模化生产的微繁方法。86%的头状花序外植体在含有2mg L−1 6-苄基胺嘌呤(BAP)的MS培养基上培养6周后产生不定芽(15.44±0.34个头状花序)。在添加BAP和topolin(各2 mg L−1)的MS培养基上，8周后的芽增殖率最高(17个芽/外植体)。在含2 mg L−1吲哚-3-丁酸(IBA)的半强MS培养基上，微芽在4周内生根成功(91.35%)。小苗驯化成活率为97.5%，开花无明显形态畸变。

Synergistic effect of benzylaminopurine and meta-Topolin combination for micropropagation of gerbera ‘Pink Melody’

ABSTRACT Gerbera (Gerbera jamesonii Bolus ex Hook. F.; Asteraceae), is one of the most economically important ornamental plants due to its aesthetic value. In the present study, we established a micropropagation method for the large-scale production of quality planting material of gerbera ‘Pink Melody’. Eighty-six percent of the capitulum explants produced adventitious shoots (15.44 ± 0.34 shoots per capitulum) on Murashige and Skoogs (MS) medium containing 2 mg L−1 6-benzylaminopurine (BAP) after six weeks of incubation. The highest shoot multiplication rate (17 shoots per explant) was obtained on MS medium supplemented with BAP and meta-Topolin (each at 2 mg L−1) after eight weeks. The micro-shoots were successfully rooted (91.35%) on half-strength MS medium containing 2 mg L−1 indole-3-butyric acid (IBA) within four weeks. The micropropagated plantlets were acclimatized with a 97.5% survival rate and produced flowers with no visible morphological aberrations.
