Research on Dynamics of the Recovery Growth of Arundinella anomala Steud.after Submergence in Water
摘要
Abstract
[Objective] To explore the differences in the recovery growth of A. anomal after submergence at different time. [Method] Three treatments were set up, namely, the control, underground submergence (underground of plants submerged in water) and complete submergence with 2 m water depth (top of plants 2 m below water surface). Three flooding durations were also set up, including 40, 60 and 90 d. The growth of A. anomala at different recovery periods was observed. [Result] After short-period submergence, the tiller number of A, anomala remained the same during the whole recovery period. Tiller number of A. anomala exposed to 90 d submergence increased quickly during the early recovery period, and it started to increase slowly during the late recovery period, but the rate of increase was still higher than that of the control plants. The abovcground biomoss of A. anomala was inhibited by long-term submergence, but it increased quickly during recovery period. [Conclusion] A. anomala still had recovery capability after submergence, especially at the primary stage of recovery growth, and it showed good tolerance to submergence.关键词
