本试验用涂片法制片,以低渗、酶解、火焰干燥以及分带等处理我国“甘肃黑麦”和加拿大黑麦“Kustro”的根尖细胞。从形态、C 带带型分析和比较了其染色体组型。两个品种无显著差异。其染色体的端粒带、核仁缢痕带都显著而较稳定。着丝点带也常出现。中间带变化较大。所有染色体分为三组:中部着丝点染色体;亚中部着丝点染色体;随体染色体。 In this experiment, the root tip cells of “Gansu Rye” and Canadian rye “Kustro” were treated with hypotonic, enzymolysis, flame drying and zonation. From the morphological, C-banding analysis and comparison of their karyotypes. No significant difference between the two varieties. The chromosome telomere, nucleolus marks are significant and more stable. Filament belt often appear. Large changes in the middle. All chromosomes are divided into three groups: central centromere chromosomes; metachromatic centromere chromosomes;
