Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

New Phytologist, Volume 250, Issue 5, Page 2933-2945, June 2026.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

Extractives elucidation of Taiwania cryptomerioides sapwood

, 2023
Taiwania (Taiwania cryptomerioides Hayata) has long been regarded as a living fossil from the Tertiary period of Mesozoic Era for its distinguished yellowish-red color with purplish-pink streaks presented in its heartwood.

Sapwood area~DBH allometries for 14 common tree species in a successional tropical forest in Thailand

, 2022
Sapwood area is an important parameter for estimating canopy transpiration in the forest water cycle. However, sapwood area highly varies across species and forest ecosystems and is difficult to measure directly.

Wettability of the surface of heat-treated juvenile teak wood assessed by drop shape analyzer

Maderas: Ciencia y Tecnología, 2018
This study investigated the effect of the heat treatment on the wettability of the surface of juvenile teak (Tectona grandis) wood assessed by drop shape analyzer. Heartwood and sapwood samples were heat-treated at 180 and 200oC.

Variation of heartwood-sapwood physicochemical properties in Populus euphratica along groundwater depth gradients in the Lower Tarim River, Northwest China

Trees, Forests and People
Variation in physical and chemical properties of Populus euphratica Oliv. heartwood and sapwood under different groundwater depths reflect species-specific water and nutrient requirements. This study examines natural P.

Histochemical and geometric alterations of sapwood in coastal Douglas-fir following mechanical damage during commercial thinning

Silva Fennica, 2011
Histochemical and geometric alterations to sapwood in mechanically damaged Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) trees were quantified 14 years after thinning. Discoloration and decay were measured in felled damaged and undamaged trees.

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

New Phytologist, Volume 250, Issue 5, Page 3001-3013, June 2026.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Can species adapt to drought using multiple strategies? Lessons from the California poppy

New Phytologist, Volume 250, Issue 5, Page 2918-2932, June 2026.
Summary Plants can escape drought by completing life cycles early, tolerate drought by increasing physiological limits, or avoid drought stress by obtaining or using water more efficiently. It remains unclear whether strategies vary within species across their distributional ranges due to trade‐offs, and whether species can exhibit plasticity in ...
