摘要

淡水大型植物的生命形式多种多样,有涌现型、沉水型、浮叶型和自由浮叶型,有的具有异叶性或多叶性。种内形态变异是大型植物种群中常见的现象;然而,对淡水大型植物形态的具体研究仍然不足,特别是在柔佛的庞天。因此,本研究旨在基于形态计量学和描述性特征来描述淡水大型植物,并记录它们的多样性和种群。为此,进行了形态测量,用科学照片记录了描述特征,并利用样方估计技术对淡水大型植物种群进行了估计。此外,还将所采集样本的形态计量学与其他研究中相同样本的形态计量学进行了比较,以显示不同测量范围的变化,并描述了描述性特征,并以统计图表的形式分析了以面积覆盖评估的人口估计。本研究结果显示柔佛州庞天水域淡水大型植物在形态计量数据上存在差异,而在表型上没有种内差异。

Morphological Characterisation and Documentation of Freshwater Macrophytes in Pontian, Johor's Water
Freshwater macrophytes exist in varied life forms for example, emergent, submerged, floating-leaved and free-floating, and some of them have a heterophylly or multiple forms. The intraspecific variation in terms of morphology is common phenomena in macrophytes population; however, specific studies on morphology of freshwater macrophytes are still insufficient, especially in Pontian, Johor. Hence, this study aimed to characterise the freshwater macrophytes based on morphometrics and descriptive characteristics as well as to document their diversity and population. Thus, the morphometric measurements were done, the descriptive characteristics were documented in scientific photographs, the population of freshwater macrophytes was also estimated by using quadrat estimation technique. Additionally, the morphometrics of some collected samples were compared with the same sample in other studies to show the variation in the range of different measurements, the descriptive characteristics were also described as well as the population estimation assessed by area coverage was analysed in the form of statistical chart. The finding in this study showed variation in morphometric data and no intraspecific variation on phenotype of freshwater macrophytes in Pontian, Johor’s water.
