“…Within each of the ten stands, two plots (c. 0.13 ha, located around 1 km apart) were sampled in order to characterize stand structure. The selected forests quadrats displayed low spatial heterogeneity in tree composition and density [48], hence the plots were large enough to capture the low spatial/range of variability of the stands. All the trees with a diameter greater than 3 cm at 1.3 m from the base (diameter at breast height; dbh) were identified, tagged, and mapped, and their diameters were measured (see Figure S1 at Supplementary Material).…”

The magnitude of drought impact in forest ecosystems depends on which group of trees are more severely affected; greater mortality of smaller trees can modulate the trajectories of succession, while the mortality of larger trees can disproportionately offset the ecosystem’s carbon balance. Several studies have documented a greater vulnerability of large trees to extreme droughts while some other studies reported a greater growth reduction in smaller trees during droughts. We tested these hypotheses by comparing tree basal area increment (BAI), drought resistance (i.e., magnitude of growth decline during drought), and resilience (i.e., magnitude of growth recovery after drought) across five different age-classes in black pine (Pinus nigra Arn. Ssp salzmannii) forests in Spain. Our results showed that the BAI patterns, drought resistance, and resilience were strongly influenced by tree age-classes. In addition, the effect of climatic water balance (precipitation minus potential evapotranspiration) on BAI significantly varied among age-classes. The effect of water balance on BAI was lower for younger age-classes (1–39 years of age) compared to older age-classes. We observed a greater growth reduction (i.e., lower resistance) in older trees (>40 years of age) during droughts compared to younger trees (<40 years of age). However, all trees, irrespective of their ages, were able to recover the growth rates after the drought. In general, younger trees showed a greater capacity in recovering the growth rate (i.e., more resilient) than older trees. We detected no significant effects of stand basal area and stand density on BAI, drought resistance, and resilience. Overall, our results indicated that growth of older trees was more negatively affected during drought. Therefore, these older/larger trees can be selected for commercial thinning, or can be released from competition, which can minimize the potential impacts of future droughts in black pine forests in Spain.

“…Esto es particularmente importante en el caso de las masas artificiales que pueden ser muy sensibles a un incremento de las situaciones de estrés hídrico debido a la estructura de este tipo de masas (Bronchalo González et al 2011;Camarero et al 2012;Candel-Pérez et al 2012;Linares et al 2012;Martínez-Vilalta et al 2012;Sánchez-Salguero et al 2012a, b). En el caso del alcornoque esta gestión adaptativa debe prestar especial cuidado al proceso de descorche y aprovechamiento (Montero y Cañellas 2003).…”

“…El estrés hídrico también favorece que las plantas resistan la sequía y las temperaturas bajas (Landis, Tinus, McDonald, & Barnett, 1989). Algunos autores seña-lan que el estrés hídrico, en la última fase de cultivo, puede incrementar el potencial de formación de raíces, factor que con frecuencia se ha relacionado con mayor supervivencia y crecimiento de las plantas en campo (Candel, Lucas, & Linares, 2012;Cochard, Hölttä, Herbette, Delzon, & Mencuccini, 2009;Hölttä, Juurola, Lindfors, & Porcar-Castell, 2012). Se considera que una planta carece de estrés hídrico si muestra valores de potencial hídrico (Ψ) superiores a -0.05 MPa; las condiciones de estrés son moderadas cuando Ψ oscila entre -0.05 y -1.0 MPa; valores de estrés entre -1.1 a -1.4 se consideran intermedios y cuando Ψ es menor a -1.5 MPa, el estrés hídrico es severo y restringe el crecimiento de las plántulas (Cleary, Zaerr, & Hamel, 1998;Lopushinsky & Max, 1990;Ritchie & Landis, 2010;PrietoRuíz et al, 2012).…”

“…Water stress also helps plants resist drought and low temperatures (Landis, Tinus, McDonald, & Barnett, 1989). Some authors suggest that water stress, in the last growth phase, may increase the potential for root formation, a factor that has often been associated with increased survival and growth of plants in the field (Candel, Lucas, & Linares, 2012 ;Cochard, Hölttä, Herbette, Delzon, & Mencuccini, 2009;Hölttä, Juurola, Lindfors, & Porcar-Castell, 2012). It is considered that a plant has no water stress when it has hydric potential values (Ψ) higher than -0.05 MPa; stress conditions are moderate when Ψ is between -0.05 and -1.0 MPa; stress values between -1.1 to -1.4 are considered intermediate and when Ψ is lower than -1.5 MPa means water stress is severe and restricts the growth of seedlings (Cleary, Zaerr, & Hamel, 1998;Lopushinsky & Max, 1990;Ritchie & Landis, 2010;Prieto-Ruíz et al, 2012).…”

Los datos se analizaron mediante prueba de permutaciones. Los resultados muestran que el riego cada 48 h causó los mejores efectos en altura (7.70 cm), diámetro (4.38 mm), biomasa total (6.59 g) e índice de calidad de Dickson (0.55). Por otro lado, el estrés hídrico originado por el tratamiento con riego cada 192 h (-1.22 MPa) limitó el crecimiento de las plántulas; sin embargo, el índice de lignificación (26.63) fue significativamente mejor (P = 0.0001) con esta frecuencia de riego. A pesar de haberse encontrado diferencias importantes (P = 0.0001) en el potencial hídrico y en las variables morfológicas, no se encontró evidencia suficiente que permita definir un tratamiento absolutamente superior para mejorar el preacondicionamiento de las plántulas en vivero. Por lo tanto, es recomendable evaluar dichos tratamientos durante mayor tiempo, además de evaluarlos en campo. ABSTRACTT hree irrigation periods (every 48, 96 and 192 hours) were evaluated with the purpose of improving the preconditioning Pinus engelmannii Carr. seedlings in nursery. Eight months old seedlings were evaluated for 40 days. The study was conducted under greenhouse conditions at the nursery of the Experimental Station Valle del Guadiana of INIFAP. The data were analyzed with a permutations test. The results show that irrigation every 48 h caused the best effects in height (7.70 cm), diameter (4.38 mm), total biomass (6.59 g) and Dickson's quality index (0.55). In contrast, water stress caused by treatment with irrigation every 192 h (-1.22 MPa) limited the growth of seedlings; however, the lignification index (26.63) was significantly better (P = 0.0001) with this frequency of irrigation. Despite having significant differences (P = 0.0001) in the hydric potential and morphological variables, there was not sufficient evidence to define an absolutely superior treatment to improve the preconditioning of seedlings in the nursery. Therefore, it is advisable to evaluate these treatments for a longer time; moreover, it is suggested to evaluate the same treatments in the plantation field.
