Tradeoffs between productivity and nitrogen conservation in wild and domesticated plants of the perennial crop Physaria (Brassicaceae)
(Wiley Blackwell Publishing, Inc, 2018-09)
Domestication of desert-adapted perennials has been proposed as an alternative to increase cropping intensity in low input environments. However, selection for high yield in perennial crops provokes indirect changes in ...
Carbon acquisition strategies uncoupled from predictions derivedfrom species life-cycle
(Elsevier Gmbh, 2015-03)
We compare carbon use strategies of congeneric annual (P. gracilis and P. angustifolia) and perennial (P. mendocina and P. pinetorum) Physaria (Brassicaceae), to evaluate the relevance of eco-physiological traits as ...
Seed oil content and phenology of Physaria species (Brassicaceae) differing in their life-cycle
(Elsevier Science, 2020-11)
Phenology of reproduction influences the concentration of the oil in the seeds, through changes in grain filling dynamics and biosynthetic activity. The objective was to evaluate differences in seed quality and phenology ...
Recruitment patterns in four species of Physaria (Brassicaceae): implications for maintenance of population density over time in both native and cultivated standsPatrones de reclutamiento en cuatro especies de Physaria (Brassicaceae): implicancias para el mantenimiento de la densidad en poblaciones silvestres y en cultivo
(Asociación Argentina de Ecología, 2016-04)
En zonas áridas, el reclutamiento de nuevos individuos es un proceso crítico que determina la viabilidad poblacional, el potencial de invasión de plantas alóctonas y el éxito en el establecimiento de cultivos. Se evaluaron ...
Relationship between photosynthetic rate, water use and leaf structure in desert annual and perennial forbs differing in their growth
(Springer, 2018-12)
Specific leaf area (SLA) is a key trait to screen plants for ecological performance and productivity; however, the relationship between SLA and photosynthesis is not always up-scalable to growth when comparing multiple ...
Age-related changes in root traits are linked to internal nitrogen cycling in the perennial forb Physaria (Brassicaceae)
(Gauthier-Villars/Editions Elsevier, 2021-08)
Age-related changes in root morphology and physiology, and the relationship with N dynamics between species that differ in resource use (i.e., conservative or acquisitive) and lifespan strategies are largely unexplored and ...
Plasticity in nitrogen conservation strategy under C gain variation in annual and perennial Physaria (Brassicaceae)
(Elsevier Gmbh, 2020-09)
Perennial plants have a greater reliance on internal cycling of nitrogen and are less influenced by external fluctuations of soil fertility than annuals. Despite their importance, the major mechanisms in which annuals and ...
