This study compared morphological and physiological responses of the two reeds, Arundo donax and Phragmites australis, grown either singly or together in pots, to various soil moisture regimes. Four-weeks-old plants were subjected to treatments for six months in a 2 × 3 factorial experiment with two species and three soil moisture regimes: well drained (WD); half flooded (½F) and completely flooded (F). Soil redox potential (E_h) in both species was higher in the WD (+58 to +83 mV) and significantly reduced in the flooded treatments (-80 to -83 mV). In both species, grown separately or together, prolonged complete flooding reduced growth rate, number and area of leaves, plant height, biomass, and root length. Flooding increased culm density and induced the development of aerenchyma and aerial adventitious roots. In both species grown separately or together, photosynthetic rates ranged from 16 to 28 µmol m⁻² s⁻¹ and were consistently higher in A. donax than in P. australis. Both species preferred moist to partially flooded conditions and exhibited symptoms of stress under complete waterlogging. Phragmites was more tolerant of waterlogging stress than Arundo.

这项研究比较了单独或一起在盆中生长的两种芦苇Arundo donax和Phragmites australis的形态和生理响应对各种土壤水分状况的影响。在一个2×3阶乘实验中，对具有4个星期龄的植物进行了为期6个月的处理，其中包括2种和3种土壤水分状况：排水良好（WD）；土壤水分充足（WD）。一半淹没（1 / 2F），完全淹没（F）。土壤氧化还原电位（E _h）中两个物种的WD都较高（+58至+83 mV），而淹水处理时则显着降低（-80至-83 mV）。在两个物种中，无论是单独生长还是一起生长，长时间完全淹没都会降低生长速度，叶片数量和面积，植物高度，生物量和根长。洪水增加了茎秆密度并诱导了气孔和气生不定根的发育。在单独或一起生长两个物种，光合速率范围从16到28微摩尔米^-2小号^-1并且是始终高于在A.竹比芦苇。两种物种均偏爱潮湿而不是部分淹没，并在完全淹水后表现出胁迫症状。芦苇比Arundo更能承受涝渍胁迫。
