Abstract

Abstract

The growth and reproduction of submerged plants are affected by the process of lake water level. However, it is still unclear how the changes of different hydrological processes and the duration of flooding affect the individual adaptability of submerged plants. In this study, we selected typical submerged plant Vallisneria spinulosa Yan of Poyang Lake as the target plant, and explored its individual adaptability characteristic under the six different flooding conditions by a mesocosm experiment. The results showed that prolonged high flooding level stresses could significantly affect the individual functional traits:plant height, leaf number, leaf length, root length, stolon length, vegetative propagation ability and total biomass. When the flooding level was more than 3.5 m, the prolonged flooding stress (over 21 days) would lead to large number of leaves apoptosis. However, when the water level exceeded 3.5 m for a short period of time (no more than 14 days), with the high flooding level stress reducing, and the normal growth of V. spinulosa could be restored. The results indicated that high water level stress and adverse flooding duration in summer were the main stress factors affecting the reduction of individual adaptability of submerged plants. This study could provide scientific theoretical support for submerged plant degradation as well as restoration of submerged vegetation.
