“…The establishment and performance of planted tree seedlings can be significantly affected by ectomycorrhizal fungi (Dunabeitia et al, 2004;Le Tacon et al, 1994;Pera et al, 1999). Ectomycorrhizal symbiosis plays a major role in two plant processes: hydro-mineral nutrition and the portioning of C within the plant, with some ultimately being transferred to ectomycorrhizal fungi (Simard et al, 2002).…”

-• We investigated the influence of Thelephora terrestris, an ectomycorrhizal fungus, on the concentration of nitrogen in needles of Pinus sylvestris L. seedlings and their mycorrhizal structure within four seasons of growth.• Seedlings were grown in four treatments: (I) inoculated + 0.030 g N, (II) inoculated + 0.045 g N, (III) non-inoculated + 0.030 g N, (IV) non-inoculated + 0.045 g N under laboratory conditions and later planted in post-agricultural land.• For inoculated treatments, statistically significant differences in N concentration of needles were observed for two-and four-year-old seedlings. The number of ectomycorrhizae and concentration of N in needles were negatively correlated. After four seasons of growth the greatest numbers of ectomycorrhizae were present on seedlings from treatment II, and the smallest on seedlings from treatment IV.• Two-year-old seedlings had been colonized by at least six different fungal taxa, i.e. Cenococcum geophilum, Hebeloma crustuliniforme, Rhizopogon sp., Suillus bovinus, Thelephora terrestris and a non-identified one. Treatments I and II were dominated by the ectomycorrhizae of T. terrestris and their number was significantly greater than in treatments III or IV. On four-year-old seedlings ectomycorrhizae of T. terrestris were dominated in all treatments, while ectomycorrhizae of Hebeloma sp. were not found.nitrogen / Scots pine / mycorrhizae / Thelephora terrestri / molecular detection Résumé -Modifications du niveau d'azote et de la structure mycorhizienne de semis de pin sylvestre inoculés par Thelephora terrestris.• L'influence du champignon ectomycorhizien Thelephora terrestris sur la concentration en azote dans les aiguilles de semis de pin sylvestre et sur la structure mycorhizienne des plants a été suivie durant quatre saisons de croissance.• Les semis ont été cultivés sous quatre traitements : (I) inoculé + 0,030 g N, (II) inoculés + 0,045 g N, (III) non inoculés + 0,030 g N, (IV) non inoculés + 0,045 g N, dans les conditions du laboratoire avant d'être plantés sur le terrain.• Dans les traitements d'inoculés, des différences significatives ont été observées dans la concentration des aiguilles en azote pour les semis de deux et quatre ans. Le nombre de mycorhizes et la concentration des aiguilles en azote étaient corrélés négativement. Après quatre saisons de croissance, le plus grand nombre de mycorhizes a été obtenu dans le traitement II et le plus petit dans le traitement IV.• Les semis de deux ans avaient été colonisés par au moins six taxons différents de champignon : Cenococcum geophilum, Hebeloma crustuliniforme, Rhizopogon sp., Suillus bovinus, Thelephora terrestris et un autre taxon indéterminé. Dans les traitements I et II, les ectomycorhizes de T. terrestris dominaient et leur nombre était plus élevé que dans les traitements III et IV. Pour les semis de quatre ans, les ectomycorhizes de T. terrestris dominaient dans tous les traitements, tandis que celles de Hebeloma sp. étaient absentes.azote / pin sylvestre / mycorhizes / Thelephora t...

-The influence of the fertilisation method: soluble (SF) vs. slow-release fertiliser (SRF) and of inoculation with Laccaria laccata (Scop.) Fr., Pisolithus tinctorius (Pers.) Coker & Couch and Melanogaster ambiguus (Vittad.) Tul & C. Tul. on ectomycorrhizal colonization and growth of Pinus pinea L. and Pinus pinaster Ait. was evaluated. For both pines, mycorrhization with L. laccata was not affected by the fertilisation method. Percentages of ectomycorrhizas (ECM) formed by P. tinctorius were dependent on the fertilisation method, the inoculum type (vegetative or spores) and the pine species involved. ECM formed by M. ambiguus were increased with fertilisation in both pines. Inoculation significantly improved P. pinea biomass when seedlings were fertilised with SRF whereas no effect was found in non-fertilised ones. For non-fertilised P. pinaster, inoculation with L. laccata and both inocula of P. tinctorius increased seedling biomass whereas fertilisation neutralised the fungal effect. Fertilisation increased P. pinea and P. pinaster biomass, independently of the inoculation treatment. Pour les deux pins, la mycorhization avec Laccaria laccata n'a pas été modifiée par la méthode de fertilisation. Le pourcentage d'ectomycorrhizes (ECM) formé by P. tinctorius dépendait de la méthode de fertilisation, su type d'inoculum (spores ou inoculum végétatif) et de l'espèce de pin. La fertilisation a augmenté les ECM produites par Melanogaster ambiguus chez les deux pins. L'inoculation a augmenté significativement la biomasse des semis de Pinus pinea lorsqu'ils ont été fertilisés avec SRF tandis qu'aucun effet n'a été trouvé pour les traitements non fertilisés. Pour les semis non fertilisés de Pinus pinaster, l'inoculation avec Laccaria laccata et avec les deux inoculums de Pisolithus tinctorius a augmenté la biomasse des semis tandis que la fertilisation a neutralisé l'effet de l'inoculation. La fertilisation a augmenté la biomasse de Pinus pinaster et de Pinus pinea indépendamment du traitement d'inoculation utilisé.Pinus pinea / Pinus pinaster / mycorhization contrôlée / champignon ectomycorhizien / pépinière de production de semis / fertilisation

The paper begins with a brief history of botany leading to the first descriptions on plant life phenomena. It then moves on to plant physiology as a science with a proper identity in the XVIII century. The works by Duhamel du Monceau and the German forester Robert Hartig are pointed out as landmarks on the way to the future ecophysiology of trees. The Symposium «The Physiology of Forest Trees», held in 1957 at the Harvard Forest, is also remarked as a step forward in the incorporation of forest trees as experimental material and the application of modern techniques in Plant Physiology. Thereafter, some topics in Ecophysiology, relevant for process-based forest management, are briefly reviewed. Tree canopy as a radiation collector and primary production factory of forest stands, carbon balance and allocation in trees, water and mineral nutrition, and modelling are the matters dealt with.Key words: tree physiology, ecophysiological parameters, forest ecosystem management. Resumen La Ecofisiología, nexo de unión entre el funcionamiento y la gestión de los ecosistemas forestalesSe hace un sucinto recorrido por la Botánica en su andadura a lo largo de los siglos para abocar a las primeras observaciones de fenómenos vitales de las plantas, que confluirán en la configuración con entidad propia de la Fisiología Vegetal en el siglo XVIII. Se destaca, por su específica referencia a los árboles, la obra de Duhamel de Monceau y, de manera especial, la del profesor de selvicultura Roberto Hartig, cuyas agudas descripciones del comportamiento funcional en monte de diversos especímenes forestales pueden enmarcarse en los prolegómenos de lo que mas de cien años más tarde constituirá la ecofisiología forestal. Se destaca, a continuación, el Simposio «The Physiology of Forest Trees» celebrado en 1957 en «Harvard Forest», que constituyó un paso importante en la incorporación de los árboles forestales como material experimental y aplicación de las técnicas modernas de fisiología vegetal a los mismos. Finalmente, se pasa revista a algunos aspectos actuales de Ecofisiología, destacando conceptos y aspectos de la misma y su proyección en la gestión de los ecosistemas forestales. Se subraya la especial significación del dosel arbóreo, perceptor de la radiación y maquinaria primaria de la producción del rodal forestal, el balance de carbono y su reparto en los árboles, el papel del agua y la nutrición mineral y los modelos de estimación de la productividad forestal basados en procesos fisiológicos.Palabras clave: fisiología, parámetros ecofisiológicos, gestión de ecosistema forestal. In the beginningLa capacidad para comprender el mundo depende del conocimiento acumulado (Jorge Wagensberg, 2004) Plant study is as old as humanity. Although Aristotle is considered the founder of Natural Sciences teaching, it is his disciple Theofrastus (born c.370 B.C.) who transmitted two treatises about botany, «A natural history of plants» and «On the Causes of Plants». He did the first classification of plants in trees, bushes, shrubs and h...
