Abstract: | The ecological studies of Cryptocoryne keei Jacobsen was conducted at Sg. Sedian and Sg. Staat, Bau, Sarawak. Three quadrates (0.5 m x 0.5 m) were established at Sg. Sedian and only one quadrate (0.5 m x 0.5 m) were established at Sg. Staat to measure the population and the distribution of the species. Water quality analysis such as pH, temperature, conductivity, turbidity, water flow, water depth and soil samples were taken to measure the ambient physical parameters for both rivers. The study comprises biomass allocation, light intensity and photosynthesis measurement. The biomass allocation were calculated and quadrate 2 from Sg. Sedian showed the highest ratio of leaf with an average of 0.1712 ± 0.04 (g/g), petiole with an average of 0.2895 ± 0.07 (g/g) and root with an average of 0.5393 ± 0.07 (g/g) for shaded area with fast water flow and deep water. A shaded area is significant high on photosynthetic gas exchange and open area are high for light intensity. |
