Genetic variation in foliar nutrient concentration in relation to foliar carbon isotope composition and tree growth with clones of the F1 hybrid between slash pine and Caribbean pine

Long-term tree growth rate, water use efficiency, and tree ring nitrogen isotope composition of Pinus massoniana L. in response to global climate change and local nitrogen deposition in Southern China

“…It meant that tree growth rate began to decrease even when tree WUE was continuously increasing, suggesting that increase in tree WUE was not sufficient to arrest the decline in tree BAI. It is possible that a decrease in stomatal conductance cause an increase in WUE with no associated change (or even a decline) in photosynthesis rate, and thus a decline in tree growth (Prasolova et al 2000(Prasolova et al , 2001(Prasolova et al , 2005Prasolova and Xu 2003;Huang et al 2008a, b, c).…”

Trends and challenges in soil research 2009: linking global climate change to local long-term forest productivity

“…Plant WUE and growth can be increased by elevated [CO 2 ] and N availability (Oren et al 2001;Prasolova and Xu 2003;Xu et al 2003;Prasolova et al 2005;Long et al 2006;Reich et al 2006;Hyvönen et al 2007;Magnani et al 2007;Huang et al 2008d, e, f), at least in the short term, but their longterm levels may be counteracted by age-related biologically declining trends (Duquesnay et al 1998;Penninckx et al 1999) and progressive nutrient limitations (Oren et al 2001;Drouet et al 2005a, b;Long et al 2006;Reich et al 2006;Hyvönen et al 2007). The mobility of elements (Penninckx et al 1999;Elhani et al 2003;Drouet et al 2005a, b;e.g., N) between adjacent tree rings and differences in stable isotope composition between components (Duquesnay et al 1998;Elhani et al 2003;Saurer et al 2004;Treydte et al 2006) of tree ring material (e.g., cellulose against whole tree ring material) can also pose problems in interpreting these ring data, with increasing margins of error.…”

The impact of available water content in previous agricultural soils on tree growth and nutritional status in young hybrid aspen plantations in Estonia

“…Also, the measure (output value) for estimation of optimum nutrient content is not always clear. In addition, genetic (clonal) background affects the phytochemistry of trees (Lindroth and Hwang 1996;Prasolova et al 2005) and thus critical levels for foliar nutrients could vary among hybrid aspen clones selected in different regions.…”
