| 摘 要： | 以太阳扇(Scaevola aemula)嫩叶、老叶、茎段、茎节为材料进行外植体筛选;以太阳扇嫩叶为外植体,研究愈伤组织诱导、不定芽分化及增殖、生根培养的适宜条件.结果表明:嫩叶为太阳扇愈伤组织诱导最佳外植体;MS+6-BA 0.50mg/L+2,4-D 0.20mg/L为愈伤组织诱导最佳培养基;MS+6-BA 0.50mg/L+NAA 0.10mg/L为芽分化最佳培养基,分化率可达96.5%;1/2MS+NAA 0.01mg/L为芽增殖最佳培养基,增殖系数最高可达3.33;糖浓度、NAA均影响太阳扇无菌苗生根,1/2MS+NAA 0.02mg/L+蔗糖30g/L为生根培养最适培养基;g腐殖质∶g珍珠岩∶g细土=2∶1∶1为组培苗移栽最佳基质,移栽成活率达75%.

| Abstract: | The young leaf,old leaf,stem segment and stem node of Sunfan(Scaevola aemula) were used in in vitro culture.The young leaf was shown to be the best explant and,therefore,was cultured to identify the optimum conditions for callus induction,adventitious bud differentiation and plantlet regeneration and rooting of this species.The results showed that the best media were MS+6-BA 0.50 mg/L+2,4-D 0.20 mg/L for callus induction,MS+6-BA 0.50 mg/L+NAA 0.10 mg/L for adventitious bud differentiation(the differentiatio... |
