The relationship between LDMC and nonstructural carbohydrate (NSC) concentrations is also explored and the seasonal vs interspecies variability of LDMC compared. * • LDMC, SDMC and shoot elongation rate (SER) were measured on a monthly basis for a minimum of 12 months. Bud growth rate (BGR) and NSC concentrations were also assessed in several of the study species. * • LDMC and SDMC decreased during shoot elongation in spring and increased in summer, showing a significant negative correlation with SER, but were unrelated to BGR. Half of the species analysed showed a positive relationship between LDMC and NSC. Seasonal fluctuations of LDMC within species were higher than interspecies differences, and species ranking was significantly affected by the month of sampling, except during winter months. * • Seasonal changes in LDMC and SDMC are mainly related to shoot elongation phenology, and NSC sink–source relationships between old and growing organs can explain this relationship in some species. Owing to the high seasonal variability in LDMC, it is recommended that samples for comparative purposes should be collected as close to the winter as possible.</style></abstract><accession-num><style face="normal" font="default" size="100%">18643937</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Palacio, Sara</style></author><author><style face="normal" font="default" size="100%">Milla, Rubén</style></author><author><style face="normal" font="default" size="100%">Albuixech, Jorge</style></author><author><style face="normal" font="default" size="100%">Pérez-Rontomé, Carmen</style></author><author><style face="normal" font="default" size="100%">Camarero, Jesús Julio</style></author><author><style face="normal" font="default" size="100%">Maestro, Melchor</style></author><author><style face="normal" font="default" size="100%">Montserrat-Martí, Gabriel</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Seasonal variability of dry matter content and its relationship with shoot growth and nonstructural carbohydrates</style></title><secondary-title><style face="normal" font="default" size="100%">New Phytologist</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Carbohydrate Metabolism</style></keyword><keyword><style  face="normal" font="default" size="100%">functional classifications</style></keyword><keyword><style  face="normal" font="default" size="100%">leaf dry matter content (LDMC)</style></keyword><keyword><style  face="normal" font="default" size="100%">leaf traits</style></keyword><keyword><style  face="normal" font="default" size="100%">leaf water status</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean</style></keyword><keyword><style  face="normal" font="default" size="100%">Phenology</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Development</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Leaves</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Leaves: growth &amp; development</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Leaves: metabolism</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Shoots</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Shoots: growth &amp; development</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Shoots: metabolism</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Stems</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Stems: growth &amp; development</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Stems: metabolism</style></keyword><keyword><style  face="normal" font="default" size="100%">Plants</style></keyword><keyword><style  face="normal" font="default" size="100%">Plants: metabolism</style></keyword><keyword><style  face="normal" font="default" size="100%">Seasons</style></keyword><keyword><style  face="normal" font="default" size="100%">shoot growth</style></keyword><keyword><style  face="normal" font="default" size="100%">Species Specificity</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2008///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/18643937http://dx.doi.org/10.1111/j.1469-8137.2008.02569.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">180</style></volume><pages><style face="normal" font="default" size="100%">133 - 142</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">* • This study assesses how different phases of shoot growth underlie seasonal change in leaf and stem dry matter content (LDMC and SDMC, respectively) of 12 woody Mediterranean species.
