Sentence examples for minimum water potential from inspiring English sources

This parameter is defined as the minimum water potential required for germination and is normally distributed within seed populations.

Mean minimum water potential Ψb50 has been found to vary among species [ 83], populations [ 84], and sites [ 41], whereas Tb is assumed mostly constant within species [ 85].

Thus, the relationship among wood density, minimum water potential and cavitation resistance does not appear to be directly influenced by wood density, but rather by a third, unexplained factor.

Hydrothermal time is defined as θHT = ∑([ΨO - Ψb]·[ Td- Tb]), where ΨO is the soil water potential in the top layer, Ψb is the minimum water potential required for germination, Td is mean daily temperature, and Tb is the species-specific minimum temperature required for germination.

It has been shown that denser woods tend to operate at more negative minimum water potentials (Ackerly 2004; Bucci et al. 2004; Santiago et al. 2004; Jacobsen et al. 2007 b, 2008; Gotsch et al. 2010) and have higher cavitation resistance (Hacke et al. 2001; Jacobsen et al. 2005; Pratt et al. 2007; Lens et al. 2011).

The physiological mechanisms were tested using a simple plant hydraulic model for gS based on homeostatic regulation of minimum leaf water potential (ΨLmin) that was originally developed for trees.

Further evidence for the co-ordination of wood density with traits across the whole-plant, including leaf size, minimum leaf water potential and possibly rooting depth was recently presented in an extensive review by Chave et al. (2009) in which the existence of a 'wood economics spectrum' was proposed.

On a subset of nine sites, it was compared to the observed minimum predawn leaf water potential over the vegetative season, which confirmed its relevance as an indicator.

Water saver plants reduce gas conductance and transpiration by maintaining constant minimum relative water content and leaf water potential under conditions of water stress.

Leaf tip water potential has been found as the minimum LWP that can be recorded at any time of stress.

The areal coverage of submerged and floating-leaved aquatic vegetation (SAV) is determined by the potential habitat space available between the minimum water level and the depth of light penetration (i.e., the photic zone).
