The study was conducted to evaluate the effects of waterlogging durations on germination (experiment 1) and on growth, physiology, and adventitious root formation (experiment 2) of sugarcane cv. ROC10 under a net-house condition. In the first experiment, sugarcane cuttings were subjected to waterlogging for 1 to 8 days, respectively and then transferred to normal condition for growth and germination evaluation. Results showed that different waterlogging durations had varying effects on germination ability of ROC10. Specifically, waterlogging of 1-3 days did not significantly affect germination, but the impact became evident from the 5-day treatment onward under waterlogging. Prolonged flooding reduced the germination rate and shoot height, and in the 8-day waterloging, ROC10 failed to germinate. In experiment 2, sugarcane plants at 100 day after transplanting were placed in plastic containers filled with 30l of water for waterlogging treatments of 5, 10 and 15 days, respectively. Here, different waterlogging treatments affected growth, physiology, and root development in ROC10. Waterlogging conditions reduced growth by decreasing shoot height, SPAD index, and Fv/Fm. Additionally, adventitious root formation was found under waterlogging conditions. Among the waterlogging treatments, the 15-day waterlogging induced the strongest adventitious root formation. The distribution of adventitious roots also varied across different nodes in stem, with most adventitious roots forming in the second and third nodes.
