“…The results have important implications for the understanding of plant growth and adaptation strategies in extremely arid regions. For the studied habitats, most plant species (except K. foliatum) extracted water from deep soil layers (>120 cm) and had a higher WUE, which could be attributed to extremely arid climate, root distribution pattern and soil properties (Ma et al 2012;Overdieck et al 2013). We detected niche differentiation for water use for the coexist desert plants in the saline land with K. foliatum rely on shallow soil water, whereas the other three species using mainly deep soil water.…”

To understand habitat associated differences in desert plant water‐use patterns, water stable oxygen isotope composition was used to determine water source and leaf carbon isotope composition (δ13C) was used to estimate long‐term water‐use efficiency in three typical habitats (saline land, sandy land and Gobi) in Dunhuang. The primary findings are: (1) in the three habitats, plant species used mainly deep soil water (>120 cm), except for Kalidium foliatum in the saline land, which relied primarily on 0–40 cm soil water; (2) in the saline land and Gobi habitat, Alhagi sparsifolia had the most negative foliar δ13C; in the sandy land, Elaeagnus angustifolia leaf was enriched in 13C than the other three species in 2011, but no species differences in foliar δ13C was observed among the four species in 2012; (3) common species (Tamarix ramosissima and A. sparsifolia) may alter their water sources to cope with habitat differences associated changes in soil water availability with deeper water sources were used in the Gobi habitat with lower soil water content (SWC) compared to in the saline land and sandy land; (4) we detected significant habitat differences in foliar δ13C in A. sparsifolia which may have resulted from differences in SWC and soil electrical conductivity. However, no habitat differences in foliar δ13C were observed in T. ramosissima, which may attribute to the strong genetic control in T. ramosissima or the ability to access stable deep soil water. Overall, the results suggest that extremely arid climate, root distribution and soil properties worked together to determine plant water uptake in Dunhuang area.

“…Previous studies have shown that WUE increased as water availability decreased (Ehleringer and Cooper 1988;Wang et al 2001;Chen et al 2004;Ma et al 2005). Therefore, leaf d 13 C can be used to explore variation in WUE and water use strategy of plants in arid and semiarid regions (Franco et al 2005;Ma et al 2012).…”

“…Thus, foliar d 13 C has been increasingly employed in plant ecological and global change studies, and its patterns and controlling factors have been often studied (Körner et al 1991;Li et al 2015;Liu et al 2014;Ma et al 2012;Peri et al 2012;Zhou et al 2011).…”

Relationships between foliar carbon isotope composition and elements of C3 species in grasslands of Inner Mongolia, China

Foliar elements and their ratios can be related to foliar carbon isotope composition (d 13 C) through their involvement in plant transpiration, photosynthesis, and osmotic adjustment. In order to investigate these relationships in grasslands of Inner Mongolia, China, d13 C and element contents of dominant C 3 species at 47 grassland sites were determined. For C 3 species, d13 C showed no correlation with carbon (C), positive correlations with nitrogen (N), nitrogen:phosphorus ratio (N/P) and carbon:phosphorus ratio (C/P), and negative correlations with phosphorus (P), potassium (K), and carbon:nitrogen ratio (C/N), while correlation with P was subsidiary to positive correlation between P and K. These correlations indicate that plants in Inner Mongolia that survive in dry conditions may profit from their higher water use efficiency via stomatal regulation and N-related photosynthetic capacity rather than K-related osmotic adjustment and P-related photosynthetic capacity. Further, plants adapt to severe environments by having higher water and phosphorus use efficiency at the expense of nitrogen use efficiency. However, these correlations differed among plant functional groups (PFGs), e.g., d13 C was negatively correlated with N in shrubs in contrast to other life forms. A possible explanation is that shrubs adapt to low N availability by having lower photosynthetic nitrogen use efficiency (PNUE), so that N is not positively related to photosynthetic rate in shrubs. Obviously, data on stomatal conductance, PNUE, and cell osmotic pressure are needed to fully understand these correlations and the strategies of plants adapted to arid environments.

“…The parameter D 13 C is an important indicator of all those conditions affecting the photosynthetic set point, i.e., the internal to atmospheric CO 2 concentration ratio (Ci/Ca) (Farquhar et al 1989). The d 13 C of plants depends on fractionation during diffusion of CO 2 into the leaf, and also on subsequent photosynthetic metabolism and water-use efficiency (WUE) independently (Farquhar et al 1982;Kume et al 2003;Hanba et al 2010;Ma et al 2012). Most carbon stored in mature rice grains originates from CO 2 assimilation during the grain filling period, with the flag leaf as the most photosynthetically active (Murchie et al 1999).…”

Stable isotopic compositions of carbon (d 13 C) and oxygen (d 18 O) in plants reflect growth conditions. Therefore, these isotopes might be good indicators of changes in environmental factors, such as variations in air temperature caused by climate change. It is predicted that climate change will lead to a greater increase in minimum air temperatures (primarily during the night) than in maximum air temperatures (primarily during the day) in many parts of Japan. In the present study, we investigated whether the d 13 C and d 18 O of the rice grain Koshihikari (Oryza sativa L.) from the northern latitudes (30.49°-37.14°) of Japan reflect variations in air temperature during grain filling and are related to the yield and proportion of first-grade rice (<15 % transparency, roundness, and cracking) as an indicator of quality. We revealed that rice d 13 C was not correlated with mean maximum or minimum air temperatures for each prefecture. By contrast, rice d18 O was positively correlated with mean minimum air temperature, suggesting that rice d18 O reflects changes in night air temperature. We further showed that an increase in the mean minimum air temperature during grain filling had a negative effect on rice yield and quality. Our findings indicate that the d18 O of rice grain may be a good indicator of physiological changes in response to minimum air temperatures during grain filling.
