The Effects of Intermittent Flooding on Seedlings of Three Forest Species

摘要: Under greenhouse conditions, seedlings of three forest species, baldcypress (Taxodium distichum), nuttall oak (Quercus nuttallii), and swamp chestnut michauxii) were subjected to an intermittent flooding subsequent physiological growth responses such conditions evaluated. Baldcypress showed no significant reductions in stomatal conductance (gs) or net photosynthetic rate (PN) response flood pulses. In gs PN significantly decreased during periods inundation, but recovered rapidly following drainage. contrast, was reduced by 71.8 % while 57.2 compared controls. displayed changes total mass species had lower leaf their respective Thus superior performance under frequent regimes due several factors including the ability for rapid recovery gas exchange soon after soil drained. failed resume functions removal flooding.
