Our objective was to identify initial seedling morphological characteristics that successfully predict ﬁeld performance of ﬁve Mediterranean species (Pinus halepensis, Quercus ilex, Quercus coccifera, Ceratonia silqua and Pistacia lentiscus). Container seedling morphology was evaluated following the nursery phase, and then seedlings were outplanted in the ﬁeld where ﬁeld survival was monitored for two successive years. Results indicate that survival can successfully be predicted from seedling initial morphological characteristics for all these species, yet not all the initial characteristics were good predictors. Survival of P. halepensis and Pist. lentiscus seedlings was positively correlated to initial seedling root-collar diameter, total dry weight and Dickson’s quality index, and can be reliably predicted by these variables. In contrast, seedling ﬁeld survival of the two Mediterranean evergreen oak species was correlated with few initial morphological attributes; initial diameter provided an accurate index to predict second-year outplanting survival for both species while height/diameter was a good survival predictor for Q. coccifera seedlings. For C. siliqua seedlings, seedlings with larger initial diameter and total biomass survive better in the ﬁeld. Thus, diameter was the common variable that accurately predicted survival for all species, which should be [5 mm for P. halepensis seedlings and[7 mm for the remaining species.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Trubat, R</style></author><author><style face="normal" font="default" size="100%">CORTINA, J</style></author><author><style face="normal" font="default" size="100%">Vilagrosa, A</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Nursery fertilization affects seedling traits but not field performance in Quercus suber L.</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Arid Environments</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">functional attributes</style></keyword><keyword><style  face="normal" font="default" size="100%">nutrient deprivation</style></keyword><keyword><style  face="normal" font="default" size="100%">root growth potential</style></keyword><keyword><style  face="normal" font="default" size="100%">seedling establishment</style></keyword><keyword><style  face="normal" font="default" size="100%">seedling quality</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier Ltd</style></publisher><volume><style face="normal" font="default" size="100%">74</style></volume><pages><style face="normal" font="default" size="100%">491-497</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The success of forest plantations in areas subjected to seasonal drought is strongly dependent on seedling traits. However, there is no consensus on the set of plant traits determining establishment success in these environments. We hypothesize that traits associated with nutritional stress, such as reduced biomass allocation and changes in root morphology, may promote seedling resistance to drought. We tested this hypothesis by assessing the effect of different fertilizer types and doses on the morphology and ﬁeld survival of Q. suber seedlings. This hypothesis had been previously tested with ﬁve Mediterranean species in a semi-arid environment. Nutrient deprivation decreased total biomass accumulation and slenderness ratio (ratio between stem height and root collar diameter). Nitrogen deprivation increased biomass allocation and decreased root growth potential. Short-term seedling survival was not related to nutritional regimes, seedling size or root growth potential. Differences in stem height between control seedlings and those subjected to nutrient manipulations increased in the ﬁeld as a result of shoot dieback and scarce growth. In contrast, differences in root collar diameter gradually vanished. Nutrient management in the nursery showed a strong potential for modifying the morphology of Q. suber seedlings but the relationship between these changes and seedling survival remains elusive</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pardos Mínguez, M.</style></author><author><style face="normal" font="default" size="100%">Cañellas, I.</style></author><author><style face="normal" font="default" size="100%">Bachiller, A.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Influencia del tamaño de bellota y del régimen de riego en la calidad de planta de alcornoque cultivada en vivero</style></title><secondary-title><style face="normal" font="default" size="100%">II Congreso Forestal Español</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">acorn size</style></keyword><keyword><style  face="normal" font="default" size="100%">irrigation</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword><keyword><style  face="normal" font="default" size="100%">seedling quality</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1997///</style></date></pub-dates></dates><pages><style face="normal" font="default" size="100%">491 - 496</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The effect of three acorn sizes (small, medium and large, 2.5, 5 and 8.8 g mean fresh weight, respectively) and two irrigation regimes (Rl=2R2) in the growth of cork oak containerized (Forest Pot 300) seedlings was studied.
