Typha domingensis is an invasive macrophyte which can be found even under low water levels. The objective of this study was to evaluate the root growth and anatomy as related to nutrient uptake and distribution of cattail under different water availabilities. Typha domingensis individuals were subjected to five water conditions: waterlogged, field capacity (FC), 75%FC and 50%FC. Nutrient contents of shoots and roots as well as the root growth and anatomy were evaluated. Lower water levels reduced root length (30%) and dry mass (90%) of cattail. Moderate drought increased aerenchyma development in root cortex but reduced the number and the diameter of xylem vessels in the vascular cylinder. Drought reduced the uptake of most nutrients; however, cattail promoted a higher translocation of macronutrients to shoot. Typha domingensis showed drought tolerance with modifications in root anatomy and higher nutrient translocation to shoots allowing its survival under mild water limitation.

香蒲是一种侵入性大型植物，即使在低水位下也可以发现。这项研究的目的是评估与不同水分利用条件下香蒲养分吸收和分配有关的根系生长和解剖结构。香蒲每个人都经历了五种水条件：浸水，田间持水量（FC），75％FC和50％FC。评价茎和根的营养含量以及根的生长和解剖结构。较低的水位降低了香蒲的根长（30％）和干重（90％）。中度干旱会增加根皮层的气孔形成，但会减少维管中木质部血管的数量和直径。干旱减少了大多数养分的吸收；然而，香蒲促进了大量营养素的转移。香蒲表现出耐旱性，其根部解剖结构发生了变化，养分向茎杆的转运更高，可以在温和的水分限制下存活。
