摘要
Solanum aethiopicum L. var "anara Adazi "是茄科一年生灌木。它的果实可食用,既可烹饪,也可作为蔬菜食用。在我们当地,S. aethiopicum变种 "anara Adazi "具有重要的营养和药用价值。但其形态、有丝分裂和减数分裂染色体的基本数量尚待评估。本研究旨在调查 S. aethiopicum 的有丝分裂和减数分裂染色体数目以及细胞学和形态学特征方面的外部特征。有丝分裂和减数分裂细胞学研究分别采用根尖和花蕾壁球技术进行。形态学研究是通过光学观察和使用手持镜头放大相当微小的部分来完成的。细胞学结果显示,该植物为二倍体,有丝分裂数为 2n=2x=24,减数分裂染色体数为 n=12。形态学结果显示,该植物在温带地区为一年生木本植物,在其他地区为多年生灌木,叶互生,羽状脉,花总状。细胞学研究表明,该植物的繁殖力和存活率很高,可用于杂交计划。总体数据对该属植物的分类特征和鉴定很有价值。
Evaluation of Cytological and Morphological Characteristics of S. aethiopicum Var “Anara Adazi” Found in Anambra State
Solanum aethiopicum L. var “anara Adazi” is a yearly shrub in the family Solanaceae. It is produced for its edible fruits which are cooked and eaten as a vegetable. In our locality, S. aethiopicum var “anara Adazi” is both nutritionally and medicinally important. But its morphological and basic mitotic and meiotic chromosomal counts are yet to be evaluated. This study was carried out to investigate the mitotic and meiotic chromosome counts and the external features of S. aethiopicum with regards to cytological and morphological characteristics. Mitotic and meiotic cytological study was done using the root tip and flower buds squash techniques, respectively. Morphological study was done by optical observations and use of hand lens to magnify those parts which are quite tiny. The Cytological result revealed the plant to be diploid with mitotic counts of 2n=2x=24 and meiotic chromosome number as n=12. The morphological result revealed among others the habit of the plant to be a fairly woody annual in the temperate or perennial shrub in other regions, leaves are alternately arranged, pinnately veined, and a racemose flower. Cytological studies indicated that the plant’s degree of fertility and viability is high and could be employed in hybridization programme. The overall data are valuable for taxonomic characterization and identification of the plant species in the genus.
