1、    植物生長調節劑對萱草不定芽誘導增殖的影響    李黎 曲彥婷 韓輝 唐煥偉 陳菲 熊燕摘 要：為解決金娃娃萱草（hemerocallis fulva）不定芽誘導過程中誘導率和增殖率較低的問題，采用植物組織培養技術，通過不定芽誘導及繼代增殖培養方法，利用顯著性分析，篩選出適宜的植物生長調節劑的種類及質量濃度，確定金娃娃萱草的最佳培養方案。結果表明：最佳不定芽誘導培養基為：ms+6-ba1.0 mg/l+naa0.3 mg/l，誘導率最高可達98.7%，最佳不定芽增殖培養基為：ms+6-ba2.0 mg/l+naa0.5 mg/l，增殖系數最高可達9

2、.0。由此可知，適宜的植物生長調節劑的種類及濃度可以顯著提高萱草不定芽的誘導率和增殖系數。關鍵詞：金娃娃萱草;不定芽;組織培養;繼代增殖;植物生長調節劑中圖分類號：s682.1    文獻標識碼：a   文章編號：1006-8023（2021）04-0022-05effects of plant growth regulators on adventitious bud induction andproliferation of  hemerocallis fulvali li1， qu yanting1*， han hui1， ta
