摘要:
研究不同浓度外源褪黑素[N-acetyl-5-methoxytryptamine,即melatonin(MEL)]对离体培养虎杖茎生长、根分化的影响。在培养基中分别添加3、6、12、24 μmol/L MEL,观察其对扦插的虎杖外植体生长的影响,并用相应浓度的IAA(indole-3-acetic acid)作对照。结果表明,各种浓度的MEL对虎杖的生长都产生明显影响,低浓度的MEL(3、6 μmol/L)有助于茎、根的生长,其中在6 μmol/L MEL作用下根长、根数、茎高、叶面积、生根率均达到最大或较大值;高浓度MEL(24 μmol/L)对虎杖生长有抑制作用。由结果可以看出,MEL可以调节离体培养虎杖的生长,其对虎杖生长的促进作用与IAA类似。
