“…Our results on DBH, height and crown diameter were not favored by the irrigation treatment; although, first-year summer irrigation appeared to be a positive and not excessively expensive option (Pardos et al, 2015) to maintain soil water content above a threshold of survival. In this context, the effect of irrigation on growth in an adult plantation differs from Butler et al (1997), who conclude that drip irrigation on a weekly basis has a positive effect on growth (up to 85% increase in DBH and up to 48% in crown diameter).…”

Introduction -Stone pine (Pinus pinea L.) is a species of economic interest for its pine nuts. Despite this market, cones are harvested mostly from natural forests. Advances in semi-intensive or intensive management for cultivating it as a fruit tree have been scarce. Fruit development is characterized by a 3-year cycle since pollination to harvesting, making nutritional and hydric management highly challenging. Materials and methods -We studied the main and interaction effects of fertilization and irrigation on growth and fruiting by a factorial design laid out in an adult stone pine plantation located in central Chile. Results and discussion -Mineral fertilization had an effect one year later on height growth (+23.5% increase) and one-year-old conelet production (+82.3% increase). After two consecutive years of mineral fertilization, significant positive impacts on diameter growth, height growth and one-year-old conelet production were observed. Irrigation enhanced fruiting but did not impact growth significantly. The highest conelet number was observed in the fertilized and irrigated experimental plots. Conclusion -Both cultural practices, applied either individually or combined, are efficient techniques to enhance fruit production of the stone pine.

“…In addition, yearly changes in evaporative demand and rainfall are also important sources of variation (Figure 1). An average of 312 L of water was applied during the summer, which was lower than that of other experimental plantations in the Mediterranean (Pardos et al, 2015), but considerably higher than that of some experiments under arid conditions in which water was supplied manually at the root level through a pipe . During the rest of the year, a considerable amount of water (approximately 50% of the yearly irrigation) was still applied during our experiment because of the low rainfall rates (Figure 1).…”

“…Irrigation of forest plantations can be necessary in Mediterranean dry areas to assure survival when the summer drought is long and severe Pardos et al, 2015). Low precipitation and the salinization of groundwater require the use of additional water resources (wastewater, desalinized water, etc.).…”

The restoration of dry lands in the Mediterranean is a challenging task because harsh abiotic conditions hamper the counteraction of feed-back degradation processes. Active restoration through planting must be performed to deter this process. In this study, we tested the influence of mineral nutrition in the nursery (two formulations of controlled release fertilizer at two rates each) and tree protection after planting (by using tube shelters) on the nine-year performance of Acacia salicina irrigated with low-quality (saline) water. The overall survival at the end of the study period was 58.2%, with the electrical conductivity of the soil saturation extract reaching 5.4 dS·m -1 after nine years. The survival and growth (in height) were greater for seedlings fertilized with more than 1.5 g·L -1 of 9-13-18, although the survival differences became significant only after the seventh year. The basal stem diameter (BSD) of seedlings that were fertilized at higher rates was significantly greater than those that were fertilized at lower rates during the first two years of planting; the differences were no longer present thereafter. The seedlings in shelters had marginally superior survival, faster growth during the first four years, and smaller BSD values after the third year compared to those of the unprotected seedlings. In comparison with a parallel study that was conducted under drought conditions, irrigation reduced some differences among treatments, but it increased others. These results emphasize the importance of the size and mineral nutrient status of nursery stock in irrigated plantations under dry Mediterranean conditions, with highly fertilized seedlings showing superior performance. Long-term planting studies are crucial for gaining a greater understanding of seedling performance and for providing a better rationale for treatment recommendations.

“…Estas condiciones agravan el hecho de que estas masas heterogéneas presenten problemas de regeneración (Manso et al, 2014), de tal forma que las proyecciones sobre sequías estivales más frecuentes, prolongadas y severas en la región afectarán negativamente al establecimiento de las plantas a corto plazo y a la regeneración de la masa a largo plazo. Las tres especies objeto de estudio (Pinus pinea, Quercus ilex y Juniperus thurifera) son especialmente sensibles, durante el estado juvenil, a las sequías prolongadas cuando crecen en espacios abiertos (Pardos et al, 2014). De hecho, la supervivencia del regenerado se ve muy negativamente afectada por la sequía estival en Quercus ilex (Ogaya y Peñuelas, 2007) y Pinus pinea (Mayoral et al, 2015).…”

El trabajo se desarrolla en las masas mixtas de pino piñonero, sabina y encina de los páramos calizos de la Meseta Norte. Se estudia la supervivencia, crecimiento, respuesta fisiológica y reparto de biomasa de una plantación de las tres especies a lo largo de un gradiente lumínico y bajo condiciones de sequía inducida. Se establecieron 12 parcelas (45 m2), divididas en dos subparcelas, a su vez con 4 bloques, donde se plantaron 9 plantas (3 plantas por especie). Se fijaron 3 niveles de luz (HL: GSF~0.75: ML: GSF~0.45; LL: GSF~ 0.26); y dos niveles de disponibilidad hídrica (Co: condiciones ambientales naturales; y W-: reducción de precipitación del 30% mediante sistema de exclusión de precipitación). El ensayo duró desde diciembre 2011 hasta mayo 2015. Se evaluó la supervivencia en 19 ocasiones y se midió la fluorescencia a la clorofila 4 veces. En mayo 2015 se hizo cosecha final, analizándose el reparto de biomasa y crecimiento. Las mayores tasas de mortalidad se registraron tras el primer verano, con efecto negativo del tratamiento HL sobre la supervivencia de encina y pino, y poco efecto de la exclusión. Bajo sombra, las tasas de supervivencia fueron mayores. La supervivencia estuvo íntimamente relacionada con su comportamiento fisiológico, modificado por el ambiente lumínico y la época del año, pero no por la exclusión. Los resultados confirman la mejor capacidad adaptativa de la sabina y la encina en estas masas mixtas, aunque a largo plazo se reducirá la resiliencia de la encina, afectando a su capacidad rebrotadora.
