“…Previous studies found that leaf stoichiometry is impacted strongly by genetics, for example life form, family, genus, species (Kerkhoff et al 2006;Li et al 2011;Yang et al 2015), and provenance or genotype (Å gren and Weih 2012; Wu et al 2014). However, we found that the effect of provenance (genetics) on leaf stoichiometry was not significant.…”

“…Plants from colder habitats, with shorter growing seasons, often have greater leaf N and P concentrations, which is typically considered an adaptive mechanism that enhances metabolic activity and growth rates at low temperatures (Van de Waal et al 2010;Chen et al 2013). Even within species, provenances from colder habitats have greater N and P concentrations (Oleksyn et al 2003;Wu et al 2014). Previous studies found that leaf nutrient concentrations are impacted strongly by soil nutrients, especially available nutrients (Han et al 2011), and the environmental nutrient supply hypothesis was proposed to explain the latitudinal trends of leaf N and P stoichiometry (Chadwick et al 1999;Reich and Oleksyn 2004).…”

“…Every two blocks as a group located in the bottom, middle, and top of slopes, respectively. Tree growth and leaf traits were also determined in our previous studies (Liu 2010;Zhang et al 2013;Wu et al 2014). Among the 36 provenances, 29 provenances with 100 % survival in all three sites were selected for the study (see Fig.…”

Plant stoichiometry varies mainly with environment and taxonomic affiliation (genetics). Understanding how environment and genetics regulate plant stoichiometry would help us to better understand stoichiometric homeostasis. Recent studies quantified the effect of environment and genetics on plant stoichiometry for multispecies over a large scale, but few studied the effect within a given species. Provenance tests are best suited to study the effect of environment (site) and genetics (provenance) on stoichiometry and assess the homeostasis for a given species. We determined leaf N and P concentrations for 29 Quercus acutissima provenances, from across the distribution in China, grown in three common gardens with different environments. Compared to the statistically insignificant provenance effect, site effect was large and statistically significant for leaf N and P stoichiometry (P \ 0.05), with 43.47, 44.04, and 59.38 % of the total variations accounted for leaf N and P concentrations and N/P ratio, respectively. Meanwhile, the slopes of SMA (Standardized Major Axis) for leaf N concentration and N/P ratio, and leaf P concentration and N/P ratio, remained similar among the sites. Our results suggest that leaf N and P stoichiometry is mainly impacted by environment for a given species, and relative stability of leaf stoichiometric relationships is found independent of site environment, which supports stoichiometric homeostasis.

Abstract:Reforestation has been widely adopted to restore soil fertility and ecosystem service function in the rocky desertification region of southwestern China. However, there has been limited research concerning the stoichiometry of carbon (C), nitrogen (N), and phosphorus (P) and nutrient resorption rate of plantations in karst ecosystems. In this study, we selected plantations of Pinus yunnanensis Franch. (PY) and Eucalyptus maideni F. Muell. (EM) in Yunnan Province. The C, N, and P concentrations and the C:N:P stoichiometry in different soil layers (0-10 cm, 10-20 cm, and 20-30 cm) were examined. The nutrient limitation and nutrient resorption efficiency were also analyzed. The leaf C and N concentrations in the PY plantation were higher than that in the EM plantation; the P concentration demonstrated the opposite trend, both in green and senesced leaves. Soil C, N, and P concentrations in the EM plantation were much greater than in the PY plantation at all three depths and decreased with the depth of the soil. In addition, the high ratios of C:P, N:P, C:Available P, and N:Available P in soil coupled with the ratios of N:P in leaves indicate that the EM plantation has a greater P deficiency than the PY plantation. In the EM plantation, the relatively low P concentrations in senesced leaves indicates efficient TP (Total phosphorus) resorption, which highlights that the high reuse proficiency of P could have favored moderating P limitation in the karst ecosystem. This research aids in understanding the stoichiometric characteristics that mediate forest properties, and provides a basis for management of vegetation in karst ecosystems.
