Characterization and Environmental Condition of Local Wolffia sp. Found in Uttaradit Province

Khai-Phum is a diminutive floating flowering plant that contains highly nutritious, high-protein, and essential amino acids but has a significant capacity to absorb environmental pollutants. This study examined natural Khai-Phum sources in Uttaradit Province and collected morphological data on Khai-Phum from natural and aquaculture situations. The data were used to choose a Khai-Phum source for water quality assessment, and the physical ecology and quality of the water were studied. It was found that all Khai-Phum samples were classified as Wolffia globosa. The water from NK, TR, and BD sources indicates the most suitable quality for the growth of Khai-Phum, with quality factors (pH, DO, and TKN) influencing the growth of Khai-Phum. However, pH, alkalinity, EC, TP, and TKN are structurally related to Khai-Phum dry weight and stomatal density.
