13C‐labeling shows the effect of hierarchy on the carbon gain of individuals and functional groups in dense field stands
Lattanzi, Fernando Alfredo; Berone, German Dario; Feneis, Wolfgang; Schnyder, Hans (Ecological Society of America, 2012-01)Measurements of resource capture by individuals, species, or functional groups coexisting in field stands improve our ability to investigate the ecophysiological basis of plant competition. But methodological and technical ... -
Selection by seed weight improves traits related to seedling establishment in Panicum coloratum L. var. makarikariense
Giordano, Mabel Cristina; Berone, German Dario; Tomas, Maria Andrea (Wiley, 2013-12)Selection for heavy seed was implemented to overcome establishment problems in Panicum coloratum var. makarikariense. A collection covering the genetic diversity of the species available in Argentina was used as a base ... -
The allocation of assimilated carbon to shoot growth: in situ assessment in natural grasslands reveals nitrogen effects and interspecific differences
Xiao, Ying Gong; Berone, German Dario; Agnusdei, Monica Graciela; Rodríguez Palma, Ricardo Manuel; Schäufele, Rudi; Lattanzi, Fernando Alfredo (2014-04)In grasslands, sustained nitrogen loading would increase the proportion of assimilated carbon allocated to shoot growth (A shoot), because it would decrease allocation to roots and also encourage the contribution of species ...
