(Aritz); Lopez, M.L. (María Luisa) Abstract: Oxalis latifolia Kunth is not reported as a weed in those regions where the first centimetres of the soil get frozen in winter. The objective of this study is to evaluate the incidence of freezing temperatures on the mortality of common and cornwall form bulbs of O.latifolia in field conditions. 30 bulbs, 15 of each form, were planted 1 cm depth in two pots in April 2001 and they were placed outdoors in Azkoitia (northern Spain). Bulbs grew normally throughout the growing season and were harvested in January 2002. The lowest temperature reported in this period was -10ºC in December 2001. At the harvest all the found apical bulbs, whether they were common or cornwall, were dead. Among the lateral bulbs, 82% and 94% of common and cornwall form died because of frosts. The difference of mortality between the forms is explained by their morphology: common form bulbils grow over stolons some of which can bury the bulbils deeper in the soil and protect them from frosts; meanwhile, cornwall form bulbils are sessile and they have no choice of being buried and protected.

(Santiago); Miguel, A.M. (Ana María) de; Palazon, C. (Carlos); Hernandez, A. (Ana); Roman, M. (Miriam) de Abstract: En este trabajo se presenta un panorama de la situación de la truficultura en España, desde sus comienzos en los años 50 a la actualidad, y sus perspectivas de futuro. Se destaca la actividad científica y técnica muy amplia, con numerosas iniciativas de investigación y experimentales desarrolladas en Centros de Investigación y Universidades españolas, que contemplan aspectos tan diversos como micorrización en vivero, certificación de planta micorrizada, ecología de la trufa, recuperación de truferas naturales, cultivo y seguimiento de plantaciones truferas, taxonomía química, control de las especies de trufa, reforestación y selvicultura trufera. La situación actual es fruto de investigaciones y trabajos, pioneros en España, de personas y entidades que vieron en la truficultura las posibilidades que la confirman, en este momento, como una actividad con alto interés económico, social y ecológico, a potenciar en áreas con escasas oportunidades agronómicas y forestales de carácter tradicional y que se enmarca, por lo tanto, en el concepto de desarrollo sostenible. Se aportan datos de producciones, precios, áreas de recogida, mercados y comercios, publicaciones, plantaciones truferas y actividad investigadora. Finalmente, se realiza un breve resumen de las perspectivas de futuro del sector trufero en España con el objetivo de establecer líneas o criterios comunes para dicha actividad.

Author(s) : Roman, M. (Miriam) de; Agerer, R. (Reinhard); Miguel, A.M. (Ana María) de Abstract: The ectomycorrhizae are characterized by black, loosely woolly, monopodial-pyramidal to irregularly pinnate systems. The outer mantle layers are pseudoparenchymatous, with angular cells and mounds of flattened cells, whereas the inner mantle layers are pseudoparenchymatous to tightly plectenchymatous. Emanating hyphae abundant, with clamps and surfaces with occasional warty patches. Dark brown rhizomorphs present, with thick central non-vessel-like hyphae surrounded by much thinner peripheral hyphae. "Quercirhiza cumulosa" is probably a member of the genus Tomentella.

(Asteraceae), a Mediterranean culture: plant and soil elementary composition, a comparison Author(s) : Marco, R. (Ricardo); Cavero, R.Y. (Rita Yolanda); Lopez, M.L. (María Luisa) Abstract: Samples of both Cynara scolymus and the relevant agricultural soil, taken along 7 different and successive stages of their growth cycle, have been submitted to AES/ICP, INAA, FRX and Kjeldahl elementary analysis. The results show that of 27 analysed elements the plant accumulates 4 (N,Na,P and W), rejects 21 elements (B,Mg,Ca,Sc,Ti,V,Cr,Mn,Fe,Co,Zn,Rb,Sr,Cs,La,Ce,Sm,Eu,Hf,Ta and Th), and accumulates or rejects 2 other (K and Br) depending on developmental stage. Comparisons with similar studies carried out on Capsicum annuum, the pepper plant, show that the "compositional plant behaviour" related to that of its soil is common to both plants as regards 21 out of the 27 studied elements (N,Mg,P,Ca,Sc,Ti,V,Cr,Mn,Fe,Zn,Rb,Sr,Cs,La,Ce,Sm,Eu,Hf,Ta and Th), while it differs by only 6 elements (B,Na,K,Co, Br and W). We may conclude that, for most of the analyzed elements (21 out of 27), both plants accumulate or reject them in the same way, the same non-metals are accumulated and the same metals are rejected in both plants. Moreover, the "rooted plant" is the most physiologically active stage. Such results may be looked at as an example of ecophysiological similarity within the vegetal living matter, in spite of its morphological and taxonomical diversity.

Author(s) : Roman, M. (Miriam) de; Agerer, R. (Reinhard); Miguel, A.M. (Ana María) de Abstract: The ectomycorrhizae are dark brown to black, monopodial-pyramidal to coralloid. The outer mantle layers are pseudoparenchymatous with angular, star-like arranged cells bearing a hyphal net of angular cells, whereas the inner layers are plectenchymatous with hyphae arranged ring-like. Mantle cell walls often thickened and darkened at the intersection of cells, especially in outer layers. Abundant emanating hyphae bearing clamps, with some highly refractive amyloid zones appearing gelatinized, i.e., as if there were no cell lumen. This ectomycorrhiza probably belongs to the genus Tomentella.
