B. F.; Sujirtha, N. Vishnukumar; Madushani, H. K. L. The goal of the current study was to gather the traditional, phytochemical, and nutritional advantages of the essential medicinal plant kohila (Lasia spinosa), an indigenous vegetable with great potential in Sri Lanka but little commercial acceptance because of its high fiber content. The plant has alkaloids, and its leaves in particular include tannins and phenolic chemicals. Fresh shoots, leaves, corms, and rhizomes are often grown and used as eatable food since they are regarded as financial assets as well. People use leaf extract as the least expensive source of multivitamins to increase their nutritional value. The kohila plant offers a wide range of therapeutic benefits, including anti-helminthic, anti-bacterial, antiinflammatory, anti-hyperlipidemic, anti-oxidant, antidiabetic, and anti-tumor activity. This study covers the prospective application of kohila in the nutritional concern due to its various therapeutic and nutritional properties. 2013-12-01T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/6917 The Effect of Water Quality on Aquaculture Productivity in Estuaries of Ampara District, Sri Lanka Fouzi, M. N. M.; Dahana, H. The coastal region of the Ampara district of Sri Lanka has a considerable number of perineal and seasonal estuaries which are poorly used for aquaculture. The reason they are not being used in aquaculture is the lack of awareness and inadequate information on the water quality parameters of these estuaries. Thus, the research has focused on investigating the water quality parameters of brackish waters in the Ampara district of Sri Lanka, with particular emphasis on their suitability for aquaculture. Water temperature, dissolved oxygen (DO), water and soil pH, salinity, conductivity, and total dissolved solids of the available estuaries or coastal wetlands in the Ampara district were investigated to assess the sites suitable for aquaculture for a full year from January to December 2018. Ambient temperature and precipitation were also recorded over the course of the year. The annual differences between the maximum and minimum level of water temperature, salinity, pH, specific conductivity, total dissolved solids, DO, and soil pH were 24.2 - 36.2ºC, 0.9- 38.2 ppt, 6.2 - 8.9, 55.5 - 62870 µs/cm, 35.5 - 37800 mg/L, 3.2 - 13.4 mg/L, and 4.0 - 7.2 respectively for the whole year of 2018. The water quality parameters investigated in the full year indicate that the culture of brackish water shrimps would be suitable in Arugam lagoon (salinity, 17.1±3.3ppt) and Komari river mouth area (salinity, 21.4±8.4ppt), and culture of freshwater fish would be better in Oluvil (5.3±3.5ppt), Addalaichenai- Konawatte and River mouth (4.1±1.2ppt), Periyamuhathuwaram (3.2±1.2ppt), and Urani lagoon (5.1±3.0ppt) in all year long. As the seasonal lagoon of Sainthamaruthu (9.8±2.6) is unpredictable and recorded with highly variable water quality parameters, it would be very risky to culture the shrimps and may be suitable for euryhaline fish culture. The Sinnamuhathuwaram lagoon (9.3±3.9 ppt) is suitable for euryhaline fish farming during the period between November and March, while it is suitable for shrimp cultivation from April to October. Pottuvil Lagoon in Kottukkal would be suitable for freshwater fish farming from November to April, and for shrimp farming from April to October. Our study concluded that the lagoons of Komari- II and Arugambay are the ideal sites for culturing shrimp in all year long. 2023-12-31T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/6916 Potential use of Aloe vera (Aloe barbadensis Miller) and Kessibissan (Cyclea peltata L.) as media additives for Anthurium tissue culture Kumari, P. G. G. R. D.; Herath, H. M. I.; Mubarak, A. N. M.; Nashath, M. N. F. -Efforts to optimize protocols, explore alternative substances, and advance research are critical to making tissue culture a sustainable and cost-effective method for mass plant propagation. Hence, the present study was conducted at the Floriculture Research and Development Unit of the Royal Botanical Gardens, Peradeniya. The objective was to evaluate the potential of using Aloe vera (Aloe barbadensis Miller) and Kesibissan (Cyclea peltata L.) as nutrient additives and gelling medium for Anthurium tissue culture. The experiment was designed using a Complete Randomized Design with seven treatments, and each experiment was replicated 15 times.The number of leaves, shoots and roots per plantlet and the explant height were measured. Based on the results, our study found that supplementing Aloe vera and Kesibissan extracts had a substantial impact on the growth parameters of Anthurium explants after one month of incubation period. Kessibissan extracts performed well on Anthurium explant growth, especially in terms of the number of leaves, roots, and plantlet height. Meanwhile, the treatment involving 700 ml of MS media and 300 ml of Aloe vera extract proved to be the most successful for Anthurium, resulting in improved leaf, root, and shoot development. Overall, our findings give useful information for improving the growth of this attractive plant and may have applications for horticultural operations, highlighting the potential benefits of natural extracts in plant tissue culture. 2023-12-31T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/6915 Optimizing Growth and Morphological attributes of Henckelia Royal Queen through Pinching and Paclobutrazol application Wickramasinghe, N. P. C. H.; Thayamini, H. Seran; Senarathne, M. M. D. J. The developing floriculture industry seeks domestic pot ornamental plants as it is not further being luxury in effort. Several endemic flowering plants have the potential to introduce as pot ornamental. But creeping growth attributes of this endemic plants should be tested with growth retardants and physical manipulations before introduce those plants into the floriculture market. A shade house factorial experiment was arranged in eight treatment combinations of pinching/non-pinching and various Paclobutrazol concentrations (0 ppm, 15 ppm, 30 ppm and 60 ppm) with eight replicates for each treatment. Paclobutrazol was applied in twice, two weeks intervals while, soil drenching and pinching was done. Results of the experiment disclosed that the plants showed better performances in growth retardation and other characters measured with the pinching and Paclobutrazol concentrations increasing, but degree of leaf deformation was increased when increase the concentration of Paclobutrazol. It was observed that 15 ppm Paclobutrazol applied plants showed balanced growth retardation and acceptable plant characters. Application of Paclobutrazol in concentration of 15 ppm along with pinching caused considerable suppression of height that makes increased floricultural value for the Henckelia plants. 2023-12-31T00:00:00Z
