Phreatophyte.
In the case of this facultative phreatophyte, continuous groundwater availability throughout the season might assure the LS elongation. However, the greater elongation of such shoots was observed during the driest years with scarce spring precipitation (2017), in contrast to FBs that extended more during the wet spring of 2018 (Figure 3).

The term "phreatophyte" derives from the classical Greek word "φρεαρ" (well, cistern). Daly used the term "phreatic water" as a synonym for groundwater for all water in the zone of water saturation.Meinzer coined the term "phreatophyte" for "a plant that habitually obtains its water supply from the zone of saturation, either directly or through the capillary fringe".Xerophyte and Phreatophyte. On a separate sheet of paper, tell how they are the same and how they are different. Desert Flower Power By Alice Knisley Matthias This poem is about plants that have adapted to live in dry climates. In the case of plants, thrive means to be extremely healthy and able to grow easily; to be successful or prosper.Genomic organization of the pepper GST gene family. All the CaGST genes are distributed randomly and unevenly in all the 13 chromosomes of pepper (Fig. S1).Chromosome 9 is the most densely ...
Phreatophyte growth along river channels also provides critical wildlife habitat because in many semi-arid regions the dense phreatophytes provide the only available cover. White-winged dove, a common Arizona game bird, is a common resident in phreatophyte areas. 1.3.0. Methods of Measurement ...

Evapotranspiration (ET) rates at the site were first measured in 1985-1987 (pre-drawdown) when the mean water table depth was 0.92 m.Populus euphratica Oliv. is a widespread phreatophytic tree species that forms riparian forests in (hyper-)arid regions of Central Asia. Its recruitment strongly relies on vegetative propagation from 'root suckers' that emerge from underground root spacers. The water transport through the spacers, a …Nov 1, 2018 · Phreatophyte control application on salt cedars initially reduced ET by approximately 20 to 35percent but the reduction was only 10 percent in the subsequent month in response to the understory growth. Culler et al. s 1982) reported that (phreatophyte removal from river floodplains in Arizona reduced phreatophyte consumption of Phreatophytes. Another modification, which increases desert plant survival, is the extension of the root system for greater root absorption. Desert plants, known as phreatophytes, grow long deep roots that are capable of reaching the water table, which depths depend on the geology and nearby water sources. Phreatophytes deep root systems allow ...

Honey mesquite is a facultative phreatophyte which extracts moisture from a large volume of soil through a well-developed root system [8,81,171]. Honey mesquite's taproot commonly reaches depths of 40 feet (12 m) when subsurface water is available , though a taproot 190 feet (58 m) deep has been observed .
The relationship between groundwater recharge and discharge is one of the most important aspects in the protection of ecologically valuable areas. Knowledge of groundwater systems is therefore a pre-requisite for up-to-date integrated land and water management. A methodology is presented for assessing the relative importance of …Unlike obligate phreatophytes, such as willows and cottonwoods, saltcedar is a facultative phreatophyte and is often able to survive under conditions where groundwater is inaccessible. The high evapotranspiration rates of saltcedar can lower the water table and alter the floristic composition in heavily infested areas. Mature plants are tolerant to a …Prosopis flexuosa is a phreatophyte species that grows in the central-west of Argentina with a rainfall less than 500 mm y −1, and accesses both underground and pluvial water sources, through horizontal (30 m) and vertical (17 m depth) stratification of its root system (Villagra et al., 2010), guaranteeing a more stable water source than ...Alhagi sparsifolia Shap. is a dominant spiny phreatophyte shrub belonging to the Fabaceae family that is distributed in the desert-oasis transition zone of northwestern China and Central Asia and plays a crucial role in sand stabilization and animal husbandry (Arndt et al., 2004; Zeng et al., 2013).Key message Despite high rates of root elongation during phreatophyte establishment, once connection to groundwater has occurred and leaf area develops, seedlings demonstrate limited capacity for root elongation in response to groundwater decline. Abstract In a water-limited environment, rapid root elongation immediately after germination can be critical for a plant to reach deeper water ...Known as a "phreatophyte" because of the ability of its very large and spreading root system to draw scarce water from grasslands, fields, and streams, it is considered a weed species by farmers and ranchers. Leaf-out in springtime is a sign to local farmers that the last frost has passed.

Results. During the dry season, we observed reverse or acropetal flow in the lateral roots of P. euphratica, a pattern consistent with hydraulic ...
Jun 7, 2021 · Overall, our results suggest groundwater depths affect P and K concentrations and resorption but not their utilization in a desert phreatophyte in its hyper-arid environment. This study provides a new insight into the phreatophytic plant nutrient cycle strategy under a changing external environment in a hyper-arid ecosystem. This was evident from the significantly reduced leaf water potential in the predawn and midday, as well as the decreased maximum net photosynthetic rate, stomatal conductance, and Huber value. Although groundwater uptake helped H. ammodendron survive, the phreatophyte struggled to thrive due to exacerbated groundwater drawdown (Xu et al., …perennial phreatophyte grown in arid and semi-arid regions. between oasis and deserts, Alhagi sparsifolia Shap. can stabilize. sand dunes, prevent land erosion, and thus support fragile.To assess the long-term response of the vegetation, we mirror aspects of the Phreatophyte Project by defining the spatial extent of our analysis using boundaries of areas included in the initial project.
