Combined effect of temporal inundation and aboveground-cutting on the growth performance of two emergent wetland plants, <i>Phragmites australis</i> and <i>Bolboschoenus planiculmis</i>

Inundation stress of 10-50 cm caused significantly greater inhibition of growth performance in <i>B. planiculmis</i> compared to <i>P. australis</i>. The combination of aboveground-cutting and inundation treatments resulted in a significant inhibitory effect on the growth performance and survival rate of <i>P. australis</i>. The growth performance of <i>P. australis</i>, including stem volume and biomass, decreased and its mortality rate increased. Our manipulated experiment suggests a combined treatment approach of moderate inundation, such as 5-10 cm for 20-30 days, and aboveground cutting to manage the overgrowth of <i>P. australis</i> in restored brackish wetlands.
