| The development of a water saving rice growing system was stemmed from an attempt to manage efficient water usage, whereby reducing level of water use but still maintaining acceptable level of yield. To be successful in implementing the water saving rice growing system, it is necessary to understand a suitable photosynthetic mechanism and photosynthetic efficiency of each rice cultivar to be grown in such system. An understanding of such knowledge will lead to a better selection of healthy and high yielding cultivars. As such, this study was aimed to compare responses of 10 Thai rice cultivars in terms of photosynthesis rate and growth in well-drained and water-logged systems. Our data indicated that almost all rice cultivars grown under either... |
