用矮壮素、脱落酸、山梨醇、丁酰肼等4种植物生长抑制剂对马铃薯“晋薯16号”进行离体保存研究,选出能够延长其保存时间的抑制剂种类和浓度水平,为马铃薯种质资源的离体保存提供科学理论和实践依据。结果表明,4种抑制剂均对马铃薯离体保存有显著的影响,最适宜常温下马铃薯离体保存的抑制剂为矮壮素400mg/L,其次为山梨醇20mg/L。离体保存后的试管苗没有发生遗传变异。 Potato “Jinshu 16” was treated with four plant growth inhibitors such as chlormequat, abscisic acid, sorbitol and butyrylhydrazide, and the type and concentration of inhibitors that could prolong their storage time Level, provide the scientific theory and practice basis for the in vitro preservation of potato germplasm resources. The results showed that all the four inhibitors had significant effects on the preservation of potato in vitro. The optimum inhibitor of chlorothalonil was 400 mg / L, followed by sorbitol 20 mg / L. There was no genetic variation in in vitro plantlets after in vitro storage.
