Abstract Cryogenic vacuum distillation (CVD) is a widely used technique for extracting plant water from stems isotopic analysis, but concerns about potential biases have emerged. Here, we leverage the Cavitron centrifugation to extract xylem and compare its signature that of CVD‐extracted bulk stem as well source water. Conducted under field conditions in tropical northern Australia, our study spans seven tree species naturally experiencing range stress levels. Our findings reveal significant deuterium bias when compared (median −14.9‰), whereas closely aligned with offset −1.9‰). We find substantial variations among (bias ranging −19.3‰ −9.1‰), intriguingly, CVD‐induced were unrelated environmental factors such relative content predawn leaf potential. These results imply inter‐specific differences may be driven by anatomical traits rather than hydraulic functioning. Additionally, data highlight use site‐specific offset, based on local water, correcting biases.

Shallow purple soils (Entisols) were widely distributed in hilly areas of southwest China and easily subjected to drought due the weak soil water retention capacity, which largely reduced crop productivity. However, impact solum thickness on ecological traits use strategies crops remain poorly understood under shallow Entisol environment. In this study, patterns physiological adaptation maize with different thicknesses investigated ascertain optimum based an in-situ experiment. Isotopic (2H 18O) tracing technique was used investigate sources for growth sloping croplands 20 cm (C1), 40 (C2), 60 (C3), 80 (C4), 100 (C5) thickness. The morphological characteristics also discussed moisture regimes. results showed storage capacity significantly increased isotopes xylem (≦40 cm) more enriched, indicating contributions from bottom water, especially dry regimes (62.3% C1, 42.8% C2, at Jul. 09). utilized by treatments greater than relatively evenly throughout profile (mean 19.3%, 19.6% 17.6%, respectively, 0–10 cm, 10–20 20–40 layer), niche breadth Maize had lower biomass higher specific leaf area (SLA) reduce transpiration rate improved efficiency (WUEi) (highest P<0.05, mean 14.8 μmol·mmol−1 regimes), accompanying photosynthetic rate, during grain mature stage. thicker (>60 yields shallower (P<0.05), that provided most important base cereal production. These findings suggested tended deep loss restraining conditions. strategy through maintaining high SLA, low height only ensured limited yields. Solum is a critical index affecting maize, we recommended plantation regions.
