摘要
一些辣椒品种的分类特性存在一定的争议。本研究的目的是利用形态特征来确定辣椒属的品种。本研究在abokuta联邦农业大学纯粹与应用植物系实验区进行(纬度:7.214952;经度:3.437090),在10个重复中使用随机完全区组设计(RCBD)。分别通过测量和目测对其进行定量和定性评价。使用统计分析系统9.2版对数据进行分析,并使用Duncan's多元极差检验以p小于0.05的值分离平均值。结果表明,累积木的生长习性直立,叶形披针形,花位下垂,花冠颜色白色,花梗果形钝,果形长,花端果形尖。冠宽103.41±(4.30)cm,单株枝数24.70±(0.15)个,开花时间73±(0.21)天,果长11.69±(0.07)cm,果宽5.78±(0.05)cm,均接近于平均值。本研究表明,该品种在形态和进化上与果苔有亲缘关系。因此,建议将C. annuum var. accuminatum重新命名为C. frutescens var. accuminatum。
MORPHOTAXONOMIC RE-CLASSIFICATION OF C. ANNUUM VAR. ACCUMINATUM FINGERH AS C. FRUTESCENS VAR. ACCUMINATUM
The taxonomic identities of some Capsicum varieties are somewhat controversial. This study is aimed at using morphological characters to ascertain the Capsicum species to which variety accuminatum belongs. The study was conducted at the Experimental Plot of the Department of Pure and Applied Botany, Federal University of Agriculture, Abeokuta (Latitude: 7.214952; Longitude: 3.437090) using a Randomized Complete Block Design (RCBD) in 10 replicates. Quantitative and qualitative characters were evaluated through measurements and visual observation respectively. Data were analyzed using Statistical Analysis Systems version 9.2 and Duncan's Multiple Range Test was used to separate means at p ˂ 0.05. The reults revealed erect growth habit, lanceolate leaf shape, pendant flower position, white corolla colour, obtuse fruit shape at pedicel, elongated fruit shape, and pointed fruit shape at blossom end on variety accuminatum as characteristic features of C. frutescens. Plant canopy width 103.41±(4.30) cm, number of branches per plant 24.70±(0.15), days to flowering 73±(0.21), fruit length 11.69±(0.07) cm and fruit width 5.78±(0.05) cm in variety accuminatum are closer to mean values in C. frutescens. This study showed that variety accuminatum is morphologically and evolutionary related to C. frutescens. Therefore, re-naming of C. annuum var. accuminatum is hereby suggested and proposed to be C. frutescens var. accuminatum.
