The limits to tree height
TLDR
Redwoods are studied, including the tallest known tree on Earth, in wet temperate forests of northern California, to estimate a maximum tree height of 122–130 m barring mechanical damage, similar to the tallest recorded trees of the past.
Trends in wood density and structure are linked to prevention of xylem implosion by negative pressure
TLDR
The more drought-tolerant the plant, the more negative the xylem pressure can become without cavitation, and the greater the internal load on thexylem conduit walls, and Dt was correlated with cavitation resistance.
Centres of plant diversity : a guide and strategy for their conservation
TLDR
This three-volume work covering nearly 250 major sites for conservation of plant diversity worldwide is concern about rapid global loss and degradation of natural ecosystems and it is hoped that areas of prime botanical importance will be ensured by an adequate commitment of resources.
Biophysical Perspectives of Xylem Evolution: is there a Tradeoff of Hydraulic Efficiency for Vulnerability to Dysfunction?
TLDR
The evolution of xylem structure is discussed in the context of the current understanding of the biophysics of water transport in plants to give an improved understandings of the relations hip between xyleM structure and function.
Relationships among xylem transport, biomechanics and storage in stems and roots of nine Rhamnaceae species of the California chaparral.
TLDR
Stems and roots differ in xylem structural and functional relationships, associated with differences in their local environment (air vs soil) and their primary functions, and they displayed a trade-off betweenxylem transport safety from cavitation and xyleM transport efficiency.
The relationship between xylem conduit diameter and cavitation caused by freezing.
TLDR
The centrifuge method, modified to include freeze-thaw cycles, may be useful in separating the interactive effects of xylem pressure and freezing on cavitation, and vulnerability to cavitation by freezing was correlated with the hydraulic conductivity per stem transverse area.
CAVITATION RESISTANCE AMONG 26 CHAPARRAL SPECIES OF SOUTHERN CALIFORNIA
TLDR
Stem mechanical strength, fiber properties, and post-fire regeneration type appear to be key factors in the evolution of cavitation resistance among chaparral shrubs.
Do Xylem Fibers Affect Vessel Cavitation Resistance?1
TLDR
The correlation between cavitation resistance and fiber wall area has not been shown previously and suggests a mechanical role for fibers in cavitation Resistance, and no tradeoff between these traits is suggested.
Xylem density, biomechanics and anatomical traits correlate with water stress in 17 evergreen shrub species of the Mediterranean‐type climate region of South Africa
TLDR
Xylem density integrates many xylem traits related to water stress tolerance, including P min, MOR and (t/b) 2 h [ , as well as percentage fibre wall, parenchyma, vessel area and fibre lumen diameter, which may be an integral trait for predicting the impact of climate change on evergreen shrubs.
Conduit diameter and drought‐induced embolism in Salvia mellifera Greene (Labiatae)
TLDR
Narrow vessels and tracheids provide an interwoven auxiliary transport system that appears to be of importance to transport when many of the wider, more efficient conduits become embolized.
