摘要 本试验采用流式细胞仪对苜蓿(Medicago sativa L.)F1代杂种花药培养再生植株进行染色体倍性检测。旨在建立高效的苜蓿花药培养体系,提高苜蓿单倍体的诱导效率,寻求一种快速简便的苜蓿倍性检测方法。检测结果为流式细胞仪矩形图上清晰地检测出二倍体、三倍体、四倍体以及二倍体加四倍体的嵌合体。50株苜蓿花药再生植株中有42株四倍体(2n=4x),2n=4x与2n=2x的混合体为5株,二倍体(2n=2x)为2株,三倍体(2n=3x)为1株。本文还讨论了苜蓿花药培养体系的建立,优化,以及筛选出了适宜制作苜蓿细胞悬浮液的缓冲液(15 mmol.L-1Tris-HCl(pH7.5);80 mmol.L-1KCl;20 mmol.L-1NaCl;2 mmol.L-1EDTA-Na2;15 mmol.L-1β-Mercaptoethanol;0.1%(V/V)TritonX-100;0.5 mmol.L-1Spermine.4HCl)及其流式细胞仪检测苜蓿倍性的适应性程序。 Ploidy levels of F1 hybrid plants,derived from anther culture in Medicago sativa L.,were determined by flow-cytometric analysis.Purpose of the study was to seek a fast and reliable method for DNA ploidy detection to establish an effective system of anther culture while improving haploid induction in Medicago sativa L.There were 42 tetraploids(2n=4x=32),5 mixoploids of diploid and tetraploid(2n=4x +2n=2x),2 diploids,1 triploid in 50 regeneration plants of anther culture.The optimization of both cell suspension buffer and anther culture system in Medicago sativa L.was also discussed in the paper.
