A single, 20-year-old mountain big sagebrush plant in Montana produced an average of 115,400 seeds/year for 3 years [ 255 ]. At Salt Creek, Utah, mountain big sagebrush averaged 17 inflorescences/plant with an average of 102 flowering heads/inflorescence. It averaged 452 seeds/branch [ 235 ].Evapotranspiration (ET) of groundwater may occur when the water table is close to the land surface or when phreatophytes draw water from below the water table. The Evapotranspiration Package requires the user to assign a maximum ET rate (R ETM) to each cell from which ET may occur.The maximum rate is used when the water table in a cell equals an assigned head value, normally equal to the ...The strong hydrotropism (groundwater-dependent) and flexible water-use strategy of T. ramosissima and P. euphratica help both species survive in hyperarid climates. The differences in the developmental environments between T. ramosissima and P. euphratica can be explained well by the different distribution characteristics of root profiles. That is, higher root plasticity helps T. ramosissima ...What is an example of a phreatophyte? Examples of phreatophytes include Welwitschia and mesquite: Prosopis glandulosa. The alfalfa, or Medicago sativa, is a widespread phreatophyte plant of great economic value.

The initial cutting of 19,000 acres of saltcedar trees, the dominant phreatophyte in the area, was completed in May 1969. Saltcedar regrowth continued each year until July 1975, when root plowing eradicated most of the regrowth.

We investigated hydraulic constraints on water uptake by velvet mesquite (Prosopis velutina Woot.) at a site with sandy-loam soil and at a site with loamy-clay soil in southeastern Arizona, USA. We predicted that trees on sandy-loam soil have less negative xylem and soil water potentials during drought and a lower resistance to xylem cavitation, and reach Ecrit (the maximum steady-state ...Watering: Arizona sycamore is an obligate phreatophyte that needs at least access to ground water in its native habitat to thrive, thus we consider it to be a mesic landscape tree that does best in Phoenix with regular applications of supplemental irrigation.sources use, and ecophysiology of the phreatophyte community, and these influences are well-documented in the literature.

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.)There were complex interactive effects among the climate factors, and different plant functional types (e.g., phreatophyte vs. non-phreatophyte) could have distinct responses to similar climate change. Therefore, effective climate-adaptive strategies should be based on careful analysis of local climate pattern and understanding of the ...Phreatophyte growth along river channels also provides critical wildlife habitat because in many semi-arid regions the dense phreatophytes provide the only available cover.

A phreatophyte is a deep- rooted plant that obtains a significant portion of the water that it needs from the phreatic zone (zone of saturation) or the capillary fringe above the phreatic zone. Phreatophytes are plants that are supplied with surface water and often have their roots constantly in touch with moisture. A phreatophyte is one that absorbs its water from a constant source on the ground.

Arid lands represent diversity hotspots for a range of plant and animal taxa, such as Asteraceae, Poaceae, Aizoaceae, Agavaceae, Cactaceae and Camphomorosmeae, as well as representing the sole refugia formerly more widely distributed taxa such as the monotypic phreatophyte Welwitschia mirabilis (with sister taxa deriving from the …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.Evapotranspiration (ET) of groundwater may occur when the water table is close to the land surface or when phreatophytes draw water from below the water table.

A phreatophyte is a plant species that has modified its root system to have an extremely long tap root [10]. In addition to providing plants with more stability, these tap roots are capable of extracting moisture from deep within the soil profile, which is an extremely important because arid desert ecosystems receive little precipitation [10].The long-term observations and experimental results confirmed that precipitation patterns and the herbaceous component were dominant drivers of the carbon dynamics in this phreatophyte-dominated ...23. 11. 2004 ...
