摘要
对两种药用植物--O. corniculata 和 O. triangularis--进行了细胞遗传学研究，以确定其特征。这两种植物都有复杂的染色体中心间期核和连续的前期染色体。发现 O. corniculata 有 2n=48 条染色体，O. triangularis 有 2n=30 条染色体。O.corniculata的染色体长度范围为0.82±0.02-1.61±0.02，O.triangularis的染色体长度范围为1.02±0.02- 2.52±0.03。角斑鱼和三角鱼的 2n 染色体互补体总长度分别为（53.52±1.19）和（46.76±0.41）。两个物种的中心粒公式存在差异，如鸡冠花 O. 为 48m，三角帆 O. 为 28m+2sm。在它们的核型中，染色体长度没有出现稳定的下降。这些特征表明，O. corniculata 和 O. triangularis 可被视为原始种。因此，汇编细胞遗传学特征将有助于确保对这两种具有重要药用价值的 Oxalis 物种进行真正的鉴定和特征描述。48(1); 135-140：2024 年 6 月
Chromosomal characterization of two medicinal plants from Bangladesh
Two medicinal plants, O. corniculata and O. triangularis, were investigated cytogenetically for proper characterization. Both plants had Complex Chromocenter interphase nuclei and Continuous prophase chromosomes. O. corniculata was discovered to have 2n=48 chromosomes and 2n=30 in O. triangularis. The chromosomal length range was 0.82±0.02-1.61±0.02 in O. corniculata and 1.02±0.02- 2.52±0.03 in O. triangularis. The total length of the 2n chromosome complement was 53.52±1.19 and 46.76±0.41 for O. corniculate and O. triangular, respectively. The two species differed in centromeric formulas, such as 48m for O. corniculata and 28m+2sm for O. triangularis. In their karyotype, no steady decrease in chromosomal length was seen. These characteristics showed that O. corniculata and O. triangularis could be considered primitive species. Therefore, compiling the cytogenetic features will be helpful to ensure the genuine identification and characterization of the two medicinally important Oxalis species.
