“…5; Table 3). This negative correlation is in accordance with findings of previous studies (Li et al 2009;Tsialtas et al 2002;Tsialtas and Maslaris 2006;Zhou et al 2013). The negative correlation could be attributed to the accumulation of K, at least in part passively through the transpiration stream, into vegetative tissues (Masle et al 1992).…”

“…Pinus tabulaeformis is negatively related to N. Negative relationships between d 13 C and K were reported for Quercus aquifolioides (Li et al 2009), Pinus tabulaeformis (Li et al 2011), sugar beet (Tsialtas and Maslaris 2006), and grassland species on QinghaiTibet Plateau (Zhou et al 2013). However, while Cao et al (2009) and Zhao et al (2007) found negative relationships between d 13 C and K for Tamarix ramosissima, Artemisia ordosica, and Hedysarum scoparium, as well, they also found positive relationships for Populus euphratica and Caragana korshinskii.…”

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.

“…A few studies conducted on the subject regard dry matter partitioning (Hole et al, 1984;Benjamin and Sutherland, 1989) but in non-limiting growing conditions. Some works on sugar beet, a crop relative to red beet, showed that the environment strongly affects sugar beet growth, root yield and sugar quality (Tsialtas and Maslaris, 2006;Hoffmann et al, 2009;Tsialtas et al, 2010Tsialtas et al, , 2011. Nevertheless the effect of water shortages on dry matter partitioning is unclear (Abdollahian-Noghabi and Froud-Williams, 1998), although the greatest reduction in dry matter accumulation usually occurs in the storage roots.…”

“…Compared with the extensive characterizations of the effects of abiotic factors on d 13 C, much less is known on how nutrient availability and d 13 C interact. Studies on the relationship between leaf nutrient concentration and d 13 C are still limited to N and exclude other nutrients (Saurer et al 1995;Tsialtas and Maslaris 2006). In addition, to date, there have been only few detailed comparisons of nutrient characteristics of plant tissues of different ages in high-altitude regions.…”

Quercus aquifolioides Rehder & E.H. Wilson, an evergreen alpine and subalpine species, occupies a wide range of habitats in the Wolong Nature Reserve, southwestern China. We measured age-related carbon (C) and nutrient (N, P, K, Mg and Ca) contents, C/N, carbon isotope composition (d 13 C) and specific leaf area (SLA) in the leaves and branches of Q. aquifolioides trees along an altitudinal gradient ranging from 2,000 to 3,600 m. The results showed that both age and altitude significantly affected the morphological and physiological properties of Q. aquifolioides. Young tissues possessed higher contents of N, P, K and Mg, lower Ca contents, both on a dry mass basis (subscript ''M'') and on a unit area basis (subscript ''A''), and lower C/N and d13 C values than did the old ones. The levels of N M and d 13 C increased with increasing altitude above 2,800 m, but decreased with increasing altitude below 2,800 m. In contrast, C/N and SLA showed opposite patterns, and other nutrient contents, including P M , K M , Ca M and Mg M , exhibited irregular changes with elevation. On the other hand, d13 C was positively correlated with N M in both leaves and branches, and negatively correlated with SLA in leaves along the altitudinal gradient. Our results also showed that both the Mg M level of leaves and the Ca M level of branches, besides the functional correlations between the N M level and the structure of leaves, are responsible for or accompanied by variation in d 13 C. In addition, d 13 C was negatively correlated with C/N in both leaves and branches along an altitudinal gradient. It follows that high-altitude plants achieve higher water use efficiency (WUE) at the expense of decreasing nitrogen use efficiency (NUE, derived from C/N), whereas plants at 2,800 m can maintain relatively higher NUE but lower WUE. These characteristics probably reflect the physiological potential of Q. aquifolioides for vigorous growth and metabolism at the optimum altitude (around 2,800 m). With increasing distance from the optimum altitude, NUE decreases. The observed intraspecific variation in the trade-off between WUE and NUE may partially explain the altitudinal distribution of Q. aquifolioides in relation to moisture and nutrient availability.
