Abstract

Coconut (Cocos nucifera L.) is commonly recognized by their heights, prevalence and long-term presence. Currently the demand for coconuts and these products is high all over the world, it is in this context that our research work is included in order to preserve and use the rich biological diversity of this palm. The main objective of this study was to determine the effect of the environment on the morphology of different organs of the coconut palm. Principal component analysis (PCA) is one of the most important statistical tools for estimating the variations between the morphological characters of individuals, which are the basis for determining the degree of polymorphism, for detecting relationships between cultivars, and for evaluating the agronomic traits for the classification of coconuts. This study was conducted on twelve coconut genotypes spread over in the Sultanate of Oman and different thirty-nine qualitative and quantitative traits were evaluated. This data set was analyzed by the principal component analysis (PCA) and UPGMA cluster. And these; the results revealed great variability in the expression of the vegetative (quantitative and qualitative) agromorphological characters related to the stipe, the leaf and the fruit. The results showed that local cultivar individuals were morphologically distinct, suggesting that it may be a polyclonal variety

从阿曼苏丹国收集的本地和进口椰子品种多样性的特征和评价
椰子(Cocos nucifera L.)通常以其高度,流行率和长期存在而被认可。目前,世界各地对椰子及其产品的需求很高,正是在这种背景下,我们的研究工作包括在保护和利用这种棕榈树丰富的生物多样性方面。本研究的主要目的是确定环境对椰子树不同器官形态的影响。主成分分析(PCA)是估算个体形态性状差异的最重要的统计工具之一,是确定多态程度、检测品种间关系和评价椰子农艺性状分类的基础。本研究对分布于阿曼苏丹国的12个椰子基因型进行了研究,并对39个不同的质量和数量性状进行了评价。采用主成分分析(PCA)和UPGMA聚类对数据集进行分析。而这些;结果表明,与茎杆、叶和果实有关的营养(数量和质量)农形态性状的表达存在很大差异。结果表明,本地品种个体形态差异明显,可能为多克隆品种
