摘要
采用甲基磺酸乙酯、叠氮化钠、吖啶橙3种诱变剂处理青檀幼苗茎尖生长点。结果表明:化学诱变剂对青檀幼苗成活具有明显的抑制作用,随浓度增大,抑制作用增强,青檀对不同诱变剂的敏感程度不同;甲基磺酸乙酯诱变率最高,叠氮化钠次之,吖啶橙最低;其中甲基磺酸乙酯诱变获得特异单株中黄色叶、花斑叶青檀表现突出。
In this study, EMS, sodium azide and acridine orange was used as mutagen at growing point stem apices of Pterocetis. tatarinowii. The result showed that seeding was significantly inhibited by chemical mutagens, the affection increased with increasing concentration. And Pteroceltis tatarinowii was with different sensitivities to different mutagens. For mutagenesis rate, EMS was the highest, followed by sodium azide, while acridine orange was the lowest, Yellow leaves and spotted leaves were outstanding in mutagenesis treated by EMS .
