In the present study, we performed a pot experiment to investigate the effects of P fertilization under drought or well-watered conditions on multiple morpho-physio-biochemical …

The phreatophyte community at the LRS consists primarily of cottonwood (Populus spp.) with lesser amounts of mulberry (Morus spp.) and willow (Salix spp.), a mix found in many watersheds in central Kansas [Eddy, 1995; Kansas Department of Agriculture, 2002] and representative of the native riparian zone vegetation over much of the High …As a facultative phreatophyte and halophyte, tamarisk has a competitive advantage over native, obligate phreatophytes (e.g. cottonwood and willow) in areas where salinities are elevated or water tables depressed, conditions characteristic of disturbed riparian environments [44,115,165,170,181,211,212]. In 1954, the State of Arizona named the Palo Verde as its State Tree. The legislature did not distinguish between the two species of this tree that are native to the State; therefore both the highly contrasting Foothill and the Blue share the honor. The dry desert adapted Foothill Palo Verde is very common (>95%) compared to the desert wash ...The dynamics of phreatophyte vegetation are strongly coupled to those of the shallow phreatic aquifers from which phreatophytes extract water. Vegetation is able to influence the depth of the water table, which, in turn, can induce stress in vegetation. These interactions are likely to affect the composition and structure of phreatophyte plant ...sources use, and ecophysiology of the phreatophyte community, and these influences are well-documented in the literature. Morpho-anatomically, for instance, the leaf area tended to be larger for trees under shallow groundwater than for trees in deep groundwa-ter [9]. Groundwater-altered trees also had a smaller vessel-lumen area than the controlThe short-term and long-term ecological responses of phreatophyte communities to water table change have rarely been investigated. Phreatophytes respond in a variety of ways to water table decline, but both the magnitude and rate of water table decline can affect vegetation, and thus ET response.Given the significance of root dynamics for phreatophyte adaptation to water stress, this study attempted to analyze the effect of root interactions with groundwater on the model-simulated ET dynamics in a field site dominated by Tamarix ramosissima, a typical groundwater-dependent plant in arid regions.

Muhlenbergia rigens is a cover for mule deer during fawning periods. Studies have equated reduced deer populations with overgrazed deergrass stands in and near cattle pasture. [9] Young shoots and leaves are grazed by deer, horses, and cattle. It is an overwintering host for many species of Lepidoptera and ladybug.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.Phreatophyte. a plant with an extremely deep root system that uses groundwater as its source of moisture. A classical example is the date palm ( Phoenix dactylifera ), which grows on oases in the Sahara and the Arabian Peninsula. (An ancient Arabic proverb says that the date palm has its head in fire and its feet in water.)The meaning of PHREATOPHYTE is a deep-rooted plant that obtains its water from the water table or the layer of soil just above it.

Seed can be collected from ripe fruits in the late spring and summer and will keep for as long as 8 years in a dry indoor environment. These plants grow best in dry to lightly moist and well-drained soil. The substrate can be sandy, gravel, or rocky but neutral to alkaline soils are preferred. The creosote plant is extremely drought resistant ...Phreatophytes are deep-rooted trees and shrubs that obtain a dependable water supply from the “phreatic surface” (Meinzer 1927), i.e., from the saturated water table, and thus …Jun 1, 2021 · Considering that Z. lotus is a facultative phreatophyte that constitutes GDEs in arid regions (Guirado et al., 2018; Tirado, 2009; Torres-García et al., 2021), water availability might not be a limiting factor for growing during the dry season. We observed that LSs can emerge at any time of the growing season, although preferably they do this ... Phreatophyte definition: a plant having very long roots that reach down to the water table or the layer above it | Meaning, pronunciation, translations and examplesGroundwater is a significant component of the hydrological cycle in arid and semi-arid areas. Its evapotranspiration is an important part of the water budget because many plants are groundwater-dependent. To restore the degraded ecosystems, the need is pressing to further our understanding of the groundwater evapotranspiration (ETg) in arid and semi-arid areas. This study employed the White ...The groundwater depth effects on phreatophyte ecophysiology had the highest relative count (53.65%), followed by large-scale tree plantation effects on the groundwater characteristics (44.37%) and ...Glutathione S-transferases (GSTs) compose a family of multifunctional enzymes involved in the numerous aspects of regulating plant growth, development, and stress response. An in silico genome ...Abstract. Ozone formation regimes are closely related to the ratio of volatile organic compounds (VOCs) to NOx. Different ranges of HCHO/NO2 indicate three formation regimes, including VOC-limited, transitional, and NOx-limited regimes. Due to the unstable interactions between a diversity of precursors, the range of the transitional regime, which …B. attenuata is a summer facultative phreatophyte, occurring where groundwater depth is 2 to >30m with groundwater accounting for between 5 to 75% of water used depending on depth to the water table. These results suggest the possibility of an obligate-facultative phreatophyte distinction. The response of phreatophytic Banksia species to ...Blue palo verde (Parkinsonia florida) is a bushy tree that grows up to 9 metres (30 feet) high.It is found in desert areas of southern California, Arizona, and northwestern Mexico, including the Baja California peninsula, and is a characteristic woody plant along washes in the Colorado desert. It features cylindrical legumes.

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.

Downward redistribution of soil water through plant roots has important consequences for water and nutrient balance of arid and semi-arid ecosystems. Nevertheless, information on the seasonal patterns and magnitudes of redistribution is lacking for all but a few plant species.
