摘要: 【目的】筛选适宜的山丹种子表面灭菌方法,优化山丹无菌播种工艺。【方法】采用无菌播种方法对山丹种子进行培养,分别以1.0% NaClO和0.1%升汞作为消毒剂对山丹种子进行消毒,采用梯度时间(0~30 min)处理,培养基为MS+6-BA 1.0 mg/L+NAA 0.1 mg/L,定期观察山丹种子发芽及生长情况。【结果】相同处理时间下,0.1%升汞处理污染率均低于1.0% NaClO处理。0.1%升汞处理下,山丹种子的发芽和生长情况优于1.0% NaClO处理。随着处理时间的延长,山丹种子萌发和生长情况呈现先增加后减少的趋势,以0.1%升汞处理15 min表现最佳,萌发率达97.78%,且幼苗生长质量优于其他处理。【结论】0.1%升汞处理15 min,山丹种子可以取得较高的萌发率和较好的幼苗生长质量。

Abstract: 【Objective】Select the optimal seed surface sterilization method to improve Lilium pumilum′s aseptic seeding procedure.【Methods】Lilium pumilum seeds were cultured using aseptic sowing method. Seeds were disinfected with 1.0% NaClO or 0.1% HgCl2 with gradient treatment duration(0-30 min). Seeds were then cultured on MS medium mixed with 6-BA 1.0 mg/L and NAA 0.1 mg/L. The germination and growth were monitored regularly.【Results】The contamination rate of 0.1% HgCl2 treatment was lower than that of 1.0% NaClO treatment at the same treatment time. Lilium pumilum seeds germination and growth were better with 0.1% HgCl2 treatment than with 1.0% NaClO treatment. Seed germination and growth increased initially then declined as treatment duration was extended. The best treatment was 15 min of 0.1% HgCl2,which had a 97.78% germination rate and superior seedling growth than the other treatments.【Conclusion】Lilium pumilum seeds had higher germination rate and better seedling growth after being treated with 0.1% HgCl2 for 15 min.
