“…along the coastal areas of southern Latin America, P. pinea has been planted frequently on poor, light textured soils, with mineral deficiencies, usually of boron and phosphorus (IREN-CORFO 1964;INTA 2018). The reported variation in diameter and height growth between and within plantations confirms that growth of this species is sensitive to soil conditions (Court-Picon et al 2004;Mutke et al 2007;Loewe-Muñoz et al 2019a). Evaristo et al (2010) reported significant differences in the mineral profile of pine nuts grown in different regions, suggesting that environment, and particularly soil types, could have an important influence.…”

“…Thus, re-fertilization would be necessary to obtain high cone production concentrated in bigger cones, thereby improving fruit quality (Calama et al 2007;Freire et al 2019). Nevertheless, a recent study concluded that pine nut production depends not only on cone number but also on pine nut number inside cones and pine nut weight (Loewe-Muñoz et al 2019b), with number of pine nuts per cone being the most import a n t f r u i t t r a i t i n d e t e r m i n i n g p i n e n u t y i e l d . Consequently, further studies are needed to determine the effect of re-fertilization on pinoli production.…”

& Key message Fertilization is a feasible management technique for Pinus pinea L. cropping, with increased cone production up to 9 years after the application and superior trunk diameter growth every year. Fertilization effects on cone size-weight indicate the value of re-fertilizing. & Context Stone pine (Pinus pinea) is a species of economic interest for its highly in demand pine nuts. Despite the high value of pine nuts, cones are harvested mostly from non-managed forests. Consequently, advances in cropping techniques, such as fertilization, are needed. & Aims To monitor the effect of fertilization on growth and cone production during 10 years after fertilization, adjusted to soil characteristics, on a 16-year-old stone pine orchard. & Methods A fertilization trial including fertilized and non-fertilized plots was established. Diameter (trunk and crown) and height were repeatedly measured in each tree for 10 years. Cones were annually harvested from each tree and counted. & Results Stone pine cone production increased significantly from the third to the ninth year of treatment, with a peak increase of 3.3 times. & Conclusion Fertilization was a useful silvicultural practice to increase stone pine cone production. Periodical fertilization is recommended.

“…Vegetative propagation helps to generate attackresistant individuals, because they retain the genotypic characteristics of the donor tree (Hartmann et al, 2014). In addition, grafting shortens the period for seed production and establishment of seed orchards of Q. affinis resistant to gall wasp (Kita et al, 2018;Loewe-Muñoz et al, 2022). The objective of the present study was to establish the necessary conditions for grafting of Q. affinis individuals tolerant to A. quercuslaurinus attack.…”

Introducción: La avispa agalladora Andricus quercuslaurinus Melika & Pujade-Villar causa la muerte de Quercus affinis Scheidw. en Acaxochitlán, Hidalgo. La capacidad genética de los progenitores con tolerancia a la plaga se puede conservar mediante propagación por injertos. Objetivos: Establecer las condiciones de propagación por injerto de individuos de Quercus affinis tolerantes al ataque de A. quercuslaurinus. Materiales y métodos: Se recolectaron varetas de cinco fenotipos tolerantes y cinco susceptibles. Se realizaron homoinjertos (púas de Q. affinis sobre patrones de Q. affinis) y heteroinjertos (Q. affinis sobre Q. rugosa Née) con las técnicas de hendidura terminal y enchapado lateral. Se realizaron pruebas en cinco fechas y con materiales de edad distinta. El prendimiento de los injertos se evaluó con ANOVA y pruebas de Tukey (P = 0.05). La probabilidad de prendimiento se determinó con el ajuste del modelo de tiempo de fallo acelerado de Weibull. Resultados y discusión: Se encontraron diferencias estadísticas (P ≤ 0.05) en el prendimiento de injertos por efecto del fenotipo. La probabilidad de prendimiento de injertos con varetas de árboles tolerantes fue 166 % mayor que con varetas de árboles susceptibles. El mayor prendimiento se obtuvo en homoinjertos (90 %) con varetas semileñosas de árboles tolerantes jóvenes (12 años) y heteroinjertos (88 %) con varetas semileñosas de árboles tolerantes adultos (35 y 40 años). Conclusiones: La propagación de individuos de Q. affinis tolerantes al ataque de A. quercuslaurinus es posible por medio de homoinjertos (árboles jóvenes) y heteroinjertos (árboles adultos) con patrones de Q. rugosa, preferentemente a inicios de otoño.

“…The species was introduced to Chile by European immigrants at the beginning of the nineteenth century and was used for forestry purposes in coastal sand dune stabilization programs for some years since 1912 (Loewe-Muñoz et al 2019). Some of those trees are still alive despite the dryness of the area (over 8 dry months per year) (Santibáñez 2017).…”

Key Message Irrigation of adult stone pine trees growing in a xeric non-native habitat had positive effects not only in stem diameter growth but also in tree response to climatic variability.• Context Stone pine is a key species from Mediterranean Europe increasingly planted in South America. The knowledge about irrigation impact on short-term stem diameter dynamics is still limited in non-native arid areas.• Aims To improve our understanding of the effect of irrigation on (1) stem diameter changes of stone pine trees in a droughtprone environment in Chile and (2) the sensitivity of the species to weather conditions. • Methods We studied daily stem diameter changes in irrigated and non-irrigated 31-year-old stone pine trees during a growing season with below average precipitation in Chile. Short-term diameter changes were recorded using high-resolution dendrometers. The detrended daily stem diameter changes, expressing tree water status, were correlated with weather variability in both irrigated and non-irrigated trees. • ResultsThe growth period lasted longer and the cumulative sum of daily changes increased by 130% in irrigated trees. Moreover, a similar correlation of tree water status with climatic variables was found in non-irrigated, with the exception of precipitation.• Conclusion Irrigation increased stone pine productivity in this xeric environment and reduced the correlations between daily stem diameter variations and local climatic variability.
