Even though fertilization has been recognized as a tool to enhance cone and pine nut production, its application is mostly based on soil characteristics rather than on the amount of nutrients extracted from harvested cones. Information on nutrient extraction is scarce, even for stone pine producing countries. To address this gap, eight plantations were selected from a latitudinal range of the stone pine planted area in Chile, with contrasting (high and low) productivity levels. Ten healthy mature three-year-old cones were sampled in each plantation, weighed, dried, and processed to obtain three cone components: kernels, shells, and cone residues (scales and core). Cone components were chemically analyzed to quantify nutrient content (N, P, K, Ca, Mg, Cu, Mn, Zn and Na). The distribution of nutrient extraction among cone components and the amount of nutrients extracted per ton of fresh cones were calculated. Nutrient extraction from stone pine cones differed among cone components, with the highest values corresponding to kernels. Nutrient extraction was not affected by plantation productivity level. Total N extraction was 3.5 kg ton−1, P extraction was 0.6 kg ton−1, and K extraction was 2.7 kg ton−1. Management practices based on stone pine cone nutritional extraction will result in an optimized, stable and sustainable cone production. 2026-01-01T00:00:00Z https://bibliotecadigital.infor.cl/handle/20.500.12220/33196 Restoration of native forests from Gorse-dominated shrublands in North Patagonia, Chile: early structural development of mixed plantations Bannister, Jan R.; Cáceres, Natalia; Vidal Ojeda, Osvaldo; Carrasco Farias, Natalia Introduction: Gorse (Ulex europaeus) is currently one of the most invasive shrub-forming species in the world. Active management has been proposed for its control, including mechanical removal, followed by Gorse suppression by competition through planted forests. Objectives: In this study, we evaluate the development of 7-year-old mixed native plantations on Chiloé Island, North Patagonia, which were established following the removal of Gorse-dominated shrublands, and define which microsite conditions can facilitate stand structural development. 2026-01-01T00:00:00Z https://bibliotecadigital.infor.cl/handle/20.500.12220/33184 Coordination among hydraulic, stomatal, and anatomical traits in Prunus dulcis L. cultivars differing in degree of isohydric and anisohydric behavior Álvarez, Carolina; Acevedo Tapia, Manuel; Sandoval Rocha, Simón Pedro; Estay, Daniela; Valero, Andrea Understanding the mechanisms underlying isohydric and anisohydric behavior in woody species is critical for predicting their performance under increasing drought stress. We combined hydraulic, anatomical, and gas exchange measurements during progressive soil drought and re-watering in three Prunus dulcis cultivars (Avijor, Isabelona, and Soleta) to evaluate how coordinated traits explain drought responses and recovery. Hydroscape analysis confirmed the isohydric–anisohydric ranking previously reported, with Avijor being the most isohydric and Soleta the most anisohydric. Across cultivars, a common sequence of responses was observed: early decline in leaf hydraulic conductivity (Kleaf), followed by turgor loss point (ΨTLP), stomatal closure, and onset of embolism. Despite this shared pattern, cultivars differed in key drought thresholds. The more anisohydric cultivars showed more negative ΨTLP, and Soleta exhibited greater stem embolism resistance than Avijor. Cultivar differentiation was also clearer in stem xylem anatomy than in leaf traits, with variation in vessel-related traits being consistent with differences in stem vulnerability. By contrast, leaf vulnerability thresholds showed no clear differences among cultivars. Relative Kleaf recovery differed among cultivars, with higher recovery in Soleta than in Avijor, while Isabelona was intermediate. This pattern may reflect that Soleta and Isabelona did not reach water potentials lower than their stem P50 during drought, unlike Avijor. The separation between leaf and stem vulnerability thresholds also varied between cultivars and was greatest in Soleta, suggesting possible inter-cultivar variability in hydraulic vulnerability segmentation. Overall, cultivar-level drought responses in almond were explained by differences in stem embolism resistance, ΨTLP, and stem xylem analysis than by stomatal behavior alone. 15 páginas 2026-01-01T00:00:00Z https://bibliotecadigital.infor.cl/handle/20.500.12220/33195 La industria de madera laminada encolada 2025 Gysling Caselli, Janina; Bañados M., Juan Carlos; Pardo V., Evaristo; Troncoso Recabarren, Hans La construcción masiva con madera ha demostrado ser clave para combatir el cambio climático y reducir el déficit habitacional global, siendo los Productos de Ingeniería en Madera esenciales para su desarrollo. En Chile, la industria con mayor trayectoria en este ámbito es la de Madera Laminada Encolada (MLE), compuesta actualmente por 12 empresas de diversos tamaños. Para analizar su realidad, el Instituto Forestal (INFOR) genera información estadística anual desde hace seis años. Este boletín presenta la segunda edición de los datos recopilados entre 2019 y 2024, ofreciendo un análisis sólido de los aspectos más relevantes del sector. 33 páginas 2026-01-01T00:00:00Z
