description Background and aims: Baccharis notosergila is presented as a productivity-reducing weed in the fields of the Salado river basin, Buenos Aires, Argentina. The aims of this work were: to describe the structure of the underground system, the origin of sprouts, locate the secretory structures and storage substance to understand the adaptation strategies of this species as well as its ability to withstand chemical and mechanical control. M&M: The collected material was examined with conventional optical microscopy techniques. Histochemical tests to identify secondary metabolites were performed, and crystals were analyzed by a scanning electron microscope. Results: The subterranean system found was a xylopodium which has high shoot bud-forming potential. Storage substance was found to be inulin. Test for starch was negative. Resins and lipids (oil drops) were identified in ducts of roots; tannins and crystals of calcium oxalate were also found in the xylopodium and roots. Conclusions: The presence of these characteristics on the underground systems could explain the frequency of this species in the floristic from Salado river basin in which alternate periods of 2 high humidity and drought. The belowground bud bank would be important to B. notosergila survival in this area with extreme climatic factors, and its resistance to mechanical and chemical control. Understanding the anatomical features of these plants is one of the steps to appropriate management of this species in the Salado river basin.

Introducción y objetivos: Baccharis notosergila es una maleza de alta incidencia que reduce la productividad en campos de la Depresión del Salado, Buenos Aires, Argentina. Los objetivos de este trabajo fueron: describir la estructura del sistema subterráneo, el origen de los brotes y localizar las estructuras secretoras y la sustancia de almacenamiento, para comprender las estrategias de adaptación de esta especie, así como su capacidad para resistir el control químico y mecánico. M&M: El material recolectado fue analizado con técnicas convencionales de microscopía óptica; se realizaron pruebas histoquímicas para identificar los metabolitos secundarios y se analizaron los cristales con microscopio electrónico de barrido. Resultados: El sistema subterráneo encontrado fue del tipo xilopodio, el cual tiene un alto potencial de formación de brotes. Como sustancias carbonadas de almacenamiento se encontró inulina; no hallándose almidón. En los conductos secretores de las raíces se identificaron resinas y aceites; también se hallaron taninos y cristales de oxalato de calcio en el xilopodio y las raíces. Conclusiones: La presencia de estas características en los sistemas subterráneos podría explicar la elevada frecuencia de esta especie en la composición florística de la cuenca del río Salado, en la que alternan períodos de alta humedad y sequía. El banco de yemas subterráneas sería importante para la subsistencia de B. notosergila en esta área con condiciones climáticas extremas y también su tolerancia al control químico y mecánico. Comprender las características anatómicas de estas plantas es uno de los pasos para el manejo adecuado de esta especie en la cuenca del río Salado.
