在多倍体甜菜育种和良繁中,细胞学镜检是确定染色体倍数性最可靠的手段。而临时制片中,采用染色剂的种类,又直接影响染色体计数的准确性和显微照相的清晰度。据国内外报道,在甜菜上,广泛采用醋酸地衣红、铁矾—苏木精、醋酸洋红挤压法。醋酸地衣红虽能制出较清晰的片子,也能进行染色体计数。但也存在几个缺点:(1)染色 In polyploid beet breeding and good propagation, cytological microscopy is the most reliable means of determining chromosome doubling. The temporary film production, the use of dye types, but also directly affect the accuracy of chromosome counts and the clarity of the photographic. According to domestic and foreign reports, widely used in licorice beet lichen red, iron alum - hematoxylin, acetic acid magenta extrusion method. Although lichen acetate red can produce a clearer film, but also for chromosome counting. However, there are several disadvantages: (1) staining
