“…Besides, the TBJ population had increased sclerification and high proportion of pith parenchyma in stem, which improves water storage capacity (Geldner, 2013;Qaderi et al, 2019). The C173 population had multilayered epidermis, and this is vital for minimizing water loss from leaf surface (Correa et al, 2015). The KPR population along railway track had a significant reduction in stem diameter but increased lignification in and outside vascular tissue.…”

Salvadora oleoides Decne. (Salvadoraceae) is a facultative and mesomorphic xerophyte, well adapted to arid and semi-arid regions. Twelve populations were selected from different ecological regions of Punjab to investigate structural modifications that are essential for water conservation, by either improving water-storing capacity or preventing water loss from the plant body, hence, enabling this species to cope with environmental extremities. We observed significant plasticity in structural features, which ensures ecological success in a variety of environmental conditions. Huge variation was seen in various tissue systems, i.e., epidermis and epidermal appendages, collenchyma, size of internal oil glands, storage parenchyma, shape, size and arrangement of vascular tissue, intensity of sclerification, and stomatal size, shape and orientation. The desert populations showed additional parenchymatous layer under multilayered epidermis, xylem completely surrounded by phloem, broad metaxylem vessels, intensive sclerification in and outside vascular tissue, and numerous and small sized stomata on abaxial leaf surface. Population from salt-affected areas showed greater stem cross-sectional area, enlarge palisade parenchymatous cells, multilayered epidermis, large storage parenchyma, and sclerified vascular bundles. Roadside populations possessed sclerified vascular bundles and dense hairiness on leaf surface.

“…It is well known that aerenchyma development is stimulated at poor phosphorus conditions (Coelho et al, 2006;Vejchasarn et al, 2016;Diaz et al, 2018) and excess phosphorus may limit the development of this tissue on some species. The aerenchyma is a key tissue for Typha species in order to diffuse air and oxygen throughout the root (Corrêa et al, 2015). Thus, reduced aerenchyma development under excess or limited phosphorus concentrations may limit T. domingensis metabolism and growth.…”

Aim The capacity of macrophytes to colonize large areas is often referred to as dependent of the investment in root system and its capacity to uptake nutrients. This work aimed to evaluate the phosphorus (P) effects on the root growth and anatomy as well as its capacity to uptake this nutrient by the aquatic macrophyte Typha domingensis. Methods Plants were grown for 60 days in nutrient solution containing 0, 0.2, 0.4, 0.6 or 0.8 mM of phosphorus. At the end of the experiment, the root length and P root content as well as the root anatomy at the maturation and meristematic zones were evaluated. Results Higher P concentrations increased the uptake of this nutrient and plant dry mass. However, the root length was reduced by higher phosphorus levels. In addition, P increased the proportion of the root cap while reduced the proportion of the procambium at the meristematic zone. Higher phosphorus concentrations reduced the xylem vessel diameter and the proportion of the vascular cylinder at the maturation zone, whereas increased phloem proportion was observed under this condition. Furthermore, higher phosphorus levels reduced the endodermis and exodermis thickness as well as the aerenchyma proportion. Conclusions Therefore, the T. domingensis P requirement is fulfilled at 0.4 mM of this nutrient and hypertrophic conditions promote the development of unfavorable root anatomical traits and reduction of the root growth.

“…Natural populations of cattail can show different densities from very low to high clustering even under similar environmental conditions (Corrêa et al 2015). Differences between high-density (HDP) and low-density populations (LDP) of Typha angustifolia L. may be related to its growth capacity, root anatomy and antioxidant system (Corrêa et al 2017).…”

Typha domingensis Pers. (Typhaceae) is found growing naturally at high and low population densities in wetlands and shows remarkable invasive potential worldwide. The objective of this study was to verify the occurrence of changes in the environmental characteristics as well as in the biometry, anatomy, photosynthesis, and nutrient uptake of T. domingensis from natural populations growing at different densities. Plants were sampled from two populations exhibiting high and low densities and were further submitted to biometric, anatomical and physiological analyses. The experimental design was completely randomized with two treatments and 15 replicates. Data were submitted to ANOVA and the Scott-Knott test (P ≤ 0.05). At a high population density, T. domingensis showed close plant spacing, a high number of plants and a large leaf area. In addition, high-density conditions promoted self-shading of the middle and lower parts of the shoots and led to increased whole plant photosynthesis. Soil nutrients were reduced under high-density conditions. In addition, plants from high-density population developed adaptations in their vascular tissues and aerenchyma. Therefore, the high-density population condition of T. domingensis causes and increased vegetative growth of these populations, as well as its invasive potential, may be related to mild self-shading, which promotes a large leaf area and high rate of photosynthesis.
