摘　　要：以毛泡桐无菌试管苗为试验材料,研究了基本培养基、激素、糖及浓度对毛泡桐组培苗不定芽增殖及生长的影响,结果表明:基本培养基、激素的种类不同导致增殖培养结果存在很大差异,在基本培养基和激素组合增殖培养中,以WPM和BAP相结合是最适宜的培养基。在调查糖的种类对增殖培养的影响中,还是以蔗糖效果最好。不同蔗糖浓度的培养试验中,随着糖浓度的增加,其增殖诱导数增多,但小苗的伸长在20 g·L^(-1)区间增长显著。The effect of basic medium,plant hormone,different sugar with varied concentration on proliferation and growth of adventitious bud was studied in this paper taking tissue culture seedling of Paulownia tomentosa as experiment material.It showed that different basic medium,hormone resulted in varied proliferation effect.WPM+BAP was optimum culture medium,and sucrose was optimum sugar.Proliferation number increased with growing sugar concentration,and 20 g·L^-1 resulted in maximum height growth.
