| Abstract |
This paper aimed to document the diversity of plant species on slightly saline soils in the Chi river basin of Northeast Thailand. Field surveys at selected sites in three provinces (Chaiyaphum, Khon Kaen and Kalasin) were conducted both in dry and rainy seasons of 2013 by using a quadrat sampling technique. Soils under the dominant plant species were collected for physical and chemical analyses. From the study, a total of 155 plant species belonging to the 72 families have been recorded. Five of those were classified as halophytes, there were Azima sarmentosa, Maytenus diversifolia, Synostema bacciformis, Pluchea indica and Gisekia pharnaceoides . The dominant species in the selected sites of three provinces were Cynodon dactylon, Heliotropium indicum, Melochia corchorifolia, Ageratum conyzoides, Coldenia procumben , Glinus oppositifolius and Panicum repens, respectively. In dry season, the averaged soil electrical conductivity under the dominant plant species at Chaiyaphum, Khon Kaen and Kalasin were 2.52, 0.7 and 0.54 dS/m, respectively. In rainy season, the averaged soil electrical conductivity under the dominant plant species were decreased to 0.61, 0.37 and 0.14 dS/m in Chaiyaphum, Khon Kaen and Kalasin, respectively. The amounts of exchangeable sodium were in the same direction at electrical conductivity values all studied areas in both seasons. Soil pH at all studied areas in both seasons were in acidic condition. However, soil pH values were lower in the dry season than the rainy season. Soil moisture under the dominant plant species were higher in the rainy season than in the dry season. |
