Species and Biomass Distribution of Aquatic Plant in Nam Oun Reservoir, Sakon Nakhon Province
Main Article Content
Abstract
Species and quantity distribution of biomass aquatic plants in Nam Oun reservoir,
Sakon Nakhon province conducted during September 2013 to August 2014. Samplings of
aquatic plants were conducted in 4 hydrological seasons, total of 6 stations, within 3 zones
by quadrant 1 × 1 meter. The result showed that 27 species and 21 families; 16 species of
marginal type, 5 species fl oating type, 5 species of submerged type and 1 species of
emerged type. Analysis of variance showed that the species and quantity of biomass
aquatic plants each time the survey signifi cant diff erence (P < 0.05), but the zone is not
statistically diff erent (P > 0.05). The total wet weight of aquatic plant was 14,589.05 g/m2.
The most quantitative of aquatic plants was found during November to January 7,179.70 g/m2.
The aquatic plants with the highest wet weight of encounter was Mimosa pigra
(4,457.78 g/m2) followed by Leersia hexandra (3,973.76 g/m2), Utricularia aurea
(1,437.23 g/m2) Nymphaea lotus (1,066.45 g/m2), and Eleocharis dulcis (832.23 g/m2).
