“…Previous studies demonstrated that leaf N and P variation reflected environmental conditions more than plant intrinsic characteristics, such as genotype (Ågren and Weih 2012) and taxonomy (Zhang et al 2012). Although root nutrient concentrations were tightly associated with root diameter (Gordon and Jackson 2000), hierarchical branching and architecture (Iversen 2014;, they were also responsive indicators of soil nutrient availability Holdaway et al 2011) and climate at global and regional scale (Chen et al 2013;Yuan et al 2011). By contrast, stem which responsible for supporting and nutrient and water transport differed significantly in its construction costs among plant growth forms.…”

“…Many studies have demonstrated that the allometric relationship between leaf N (N L ) and leaf P (P L ) are similar at various scales, spanning from the local to global scale, with ranges of 0.67 to 0.72 for slopes (a) of the scaling functions (Garten 1976;Han et al 2005;Kerkhoff et al 2006;Reich et al 2010;Wright et al 2004). Furthermore, allometric relationship have also been detected in the roots and stems, for which the slopes (a) of the scaling functions are 0.76 (Yuan et al 2011) and 0.70 (Kerkhoff et al 2006), respectively.…”

“…Basically, the weighted mean C content (WMCC) of plants, especially woody plants, was useful for precise C stock estimation (Zhang et al, 2009). However, it is hard to obtain available data of C content and biomass allocation for every species and organ in diverse vegetation.…”

“…Using the default value of 50 % as biomass C con-version factor which ignores the variation of C content may lead to biases (Zhang et al, 2009;Martin and Thomas, 2011;Rodrigues et al, 2015). For example, a change of 1 % wood C content from the canonical value of 50 % can bring up to ∼ 7 Pg C variation in global vegetation C stocks, which is almost equivalent to half of the vegetation C stocks of the continental United States (Dixon et al, 1994;Jones and O'Hara, 2016).…”

Abstract. Plant carbon (C) content is one of the most important plant traits and is critical to the assessment of global C cycle and ecological stoichiometry; however, the global variations in plant C content remain poorly understood. In this study, we conducted a global analysis of the plant C content by synthesizing data from 4318 species to document specific values and their variation of the C content across plant organs and life forms. Plant organ C contents ranged from 45.0 % in reproductive organs to 47.9 % in stems at global scales, which were significantly lower than the widely employed canonical value of 50 %. Plant C content in leaves (global mean of 46.9 %) was higher than that in roots (45.6 %). Across life forms, woody plants exhibited higher C content than herbaceous plants. Conifers, relative to broad-leaved woody species, had higher C content in roots, leaves, and stems. Plant C content tended to show a decrease with increasing latitude. The life form explained more variation of the C content than climate. Our findings suggest that specific C content values of different organs and life forms developed in our study should be incorporated into the estimations of regional and global vegetation biomass C stocks.

“…Their ratios defined as nutrient stoichiometry could as a tool for analyzing the balance between the nutrition elements required by organisms and affects nutrient cycling (Sterner and Elser, 2002). Soil C: N: P stoichiometry patterns could enhance our understanding of nutrient cycling and biological processes in terrestrial ecosystems (Tian et al, 2010;Yuan et al, 2011;Ding et al, 2014). Soil N: P dynamics directly reflect the availability of N and P, but are influenced by biotic and abiotic factors as well (Jiao et al, 2013;Farooq et al, 2014).…”

Nitrogen fertilizer is the most commonly fertilizer for increasing grain yield of wheat, but its effects on wheat carbon (C), nitrogen (N) and phosphorus (P) availability are not clear yet. This field experiment was conducted to evaluate the C, N and P stoichiometry characteristics of winter wheat and soil and their relationship during the anthesis and harvest stages under nitrogen fertilization (0, 180, 360 kg ha -1 ) in Northwest China. We found that N fertilization could increase N contents, C: P and N: P ratios and decrease P contents, C: N ratio in wheat. During anthesis, the highest N and P contents were found in the flag leaf and culm, respectively and at harvest, N and P contents were higher in the grain. N and P contents in all tissues of wheat were related, and more importantly, a significant relationship with the soil N and P contents was found, these results could help us understand the nutritional balance regulation in wheat under nitrogen fertilization.
