Root elongation was measured in mature Eucalyptus pauciflora Sieber ex Sprengel subsp. pauciflora trees in a high-elevation stand, and in seedlings of E. pauciflora and E. nitens (Deane & Maiden) grown in a glasshouse. Elongation of non-mycorrhizal roots (>10 mm long) was measured at 0600 and 1800 h on several consecutive days. Root elongation of seedlings of both species in the glasshouse was greater than that of mature E. pauciflora trees in the forest. For seedlings of comparable size, roots… Expand
Root elongation in tropical Eucalyptus plantations: effect of soil water content
Abstract• Sustainability of Eucalyptus plantations is often questioned in resource-limited environments, especially in areas characterized by soils with poor nutrient and water holding capacities.Expand
Toward a rooting protocol for eucalyptus dunnii
Eucalyptus dunnii exhibits fast growth, low lignin and high cellulose contents, traits that are highly desirable for pulp production and are therefore favoured by the paper industry. In this study,Expand
An evaluation of inexpensive methods for root image acquisition when using rhizotrons
BackgroundBelowground processes play an essential role in ecosystem nutrient cycling and the global carbon budget cycle. Quantifying fine root growth is crucial to the understanding of ecosystemExpand
Soil physical properties and root growth of radiata pine

Soil water potential decreased exponentially and soil strength increased logarithmically as the volumetric water content decreased in soils of contrasting texture at a range of bulk densities. SoilExpand
Daytime depression in tree stem CO2 efflux rates: is it caused by low stem turgor pressure?
TLDR
Daytime depressions in stem FCO2 correlate with the daily dynamics of turgor, as a measure of the water status in the living stem tissues: it is suggested that water status of tree stems is a potentially important determinant of stem F CO2, as it influences the rate of growth and maintenance processes in the lives of the stem.

Sap velocity as an indicator of diurnal and long- term hydraulic resistance changes in mature 'Walker' hybrid poplar trees 1
Hydraulic resistance directly limits sap flow in trees so that understanding water-use patterns in poplar trees requires knowledge about diurnal and long-term changes in resistances in theExpand

The terrestrial methane budget varies between different vegetation types and soil conditions and is highly uncertain for alpine grasslands. This work used eddy covariance techniques to continuouslyExpand
Differential responses to changes in growth temperature between trees from different functional groups and biomes: a review and synthesis of data.
TLDR
It was found that elevated temperatures enhanced growth in deciduous species more than in evergreen trees, and Tropical species were indeed more susceptible to warming-induced growth declines than temperate or boreal trees in both analyses. Expand
Sap velocity as an indicator of diurnal and long-term hydraulic resistance changes in mature ‘Walker’ hybrid poplar treesThis article is one of a selection of papers published in the Special Issue on Poplar Research in Canada.
TLDR
An increase in hydraulic resistance was required to explain the decrease in sap velocity (V) when VPD was high, and bulk soil water potential did not change significantly, which implied that the water potential difference (ΔΨ) remained diurnally constant. Expand
Mature tree transplanting: Science supports best management practice
TLDR
Understanding of tree biology and horticulture contributing to the successful transplanting of trees, e.g. root loss and regrowth, water stress, carbohydrate status, root ball size, preparatory root and canopy pruning, timing of operations is summarised. Expand

Diurnal Changes in Diameters of Fruits and Tree Stems of Montmorency Cherry
TLDR
Diurnal expansion and contraction of fruits and tree stems of Montmorency cherry were studied during various stages of fruit development, and the amount, time, and ending of daily shrinkage were correlated with conditions affecting transpiration. Expand
Diurnal variation in extension growth of leaves of Salix viminalis.
TLDR
Extension growth rate correlated well with air temperature, suggesting that the rate of leaf expansion may have been limited by a temperature-dependent rate of cell wall loosening. Expand

TLDR
Factors that affect the photosynthetic production of the shoot system of 1-yr-old seedlings markedly affected root elongation rates and may be a factor in the establishment of sugar maple seedlings. Expand
Increased root growth in elevated CO2: a biophysical analysis of root cell elongation
TLDR
Results suggest that root growth is enhanced following increased cell expansion and that increased P and cell wall tensiometric extensibility are both important for root growth in elevated CO2. Expand
Temperature and growth‐induced water potential
When the steins of dark-grown soybean [Glycine max (L.) Merr.] seedlings grew rapidly at favorable temperatures in saturating humidities, a water potential of about 0·2 MPa was induced by growthExpand
Root Growth Maintenance at Low Water Potentials (Increased Activity of Xyloglucan Endotransglycosylase and Its Possible Regulation by Abscisic Acid)
TLDR
It is demonstrated that increased XET activity is associated with maintenance of root elongation at low [psi]w and that this response requires increased ABA. Expand
Diurnal variations in root diameter.
TLDR
The data reported here, obtained at the Auburn Rhizotron where roots in soil may be observed through transparent panels while tops are exposed to field conditions, show that lateral roots do indeed undergo diurnal variations in diameter. Expand
An evaluation of techniques for measuring yield turgor in excised Salix leaves
Abstract. The use of three techniques for determining yield turgor in excised Salix leaves was investigated. These were the osmotic-solutions technique, the psychrometer technique, and theExpand
Measurement of Yield Threshold and Cell Wal Extensibility of Intact Wheat Roots under Different Ionic, Osmotic and Temperature Treatments
TLDR
Yield stress threshold and volumetric extensibility are the rheological properties that appear to control root growth in wheat roots measured by means of parallel measurement of the growth rate of intact wheat roots and of the turgor pressures of individual cells within the expansion zone. Expand
Biophysical and biochemical control of cell expansion in roots and leaves
TLDR
By simultaneously measuring growth rate at near-single cell resolution and single cell turgor pressure, the behaviour of an expanding cell as it passes from the meristem to the mature region of the roots of maize, wheat, barley, tomato, and Pinus pinaster is charted. Expand
