Since this reproductive behavior is mostly observed in anemophilous plants, pollination efﬁciency is suggested as one hypothesis to explain it, although resource-based hypotheses are also suggested as alternatives. We analyzed the effect of ﬂowering phenology, airborne pollen presence and meteorological conditions in the pattern of acorn production in mixed evergreendeciduous oak forests (Quercus ilex and Quercus pubescens) in NE Spain for twelve years (1998e2009). In both oaks, higher temperatures advanced the onset of ﬂowering and increased the amount of airborne pollen. Nevertheless, inter-annual differences in pollen production did not inﬂuence acorn crop size. Acorn production was enhanced by a delay in ﬂowering onset in Q. ilex but not in Q. pubescens. This suggests that in perennial oaks a larger number of photosynthates produced before ﬂowering could beneﬁt reproduction while the lack of effects on deciduous oaks could be because these species ﬂush new leaves and ﬂowers at the same time. Notwithstanding this effect, spring water deﬁcit was the most relevant factor in explaining inter-annual variability in acorn production in both species. Considering that future climate scenarios predict progressive warmer and dryer spring seasons in the Mediterranean Basin, this might result in earlier onsets of ﬂowering and higher water deﬁcits that would constrain acorn production.</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%">Pignone, Domenico</style></author><author><style face="normal" font="default" size="100%">Laghetti, Gaetano</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">On sweet acorn (Quercus spp.) cake tradition in Italian cultural and ethnic islands</style></title><secondary-title><style face="normal" font="default" size="100%">Genetic Resources and Crop Evolution</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">acorn</style></keyword><keyword><style  face="normal" font="default" size="100%">Cultural islands</style></keyword><keyword><style  face="normal" font="default" size="100%">Ethnobotany</style></keyword><keyword><style  face="normal" font="default" size="100%">Neglected food</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus spp.</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s10722-010-9625-x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">57</style></volume><pages><style face="normal" font="default" size="100%">1261 - 1266</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The CNR-IGV, over the last 15 years, has organized and performed expeditions aimed at collecting germplasm and local knowledge on plants used by local populations in isolated areas, such as geographical islands, or local communities that for ethnic or cultural reasons have maintained to a certain degree their isolation from surrounding populations (cultural islands). In two such cultural islands (Bovesia, Calabria region, south-west mainland Italy, and Ogliastra, Sardinia island, Italy) a tradition regarding the use of acorns for preparing a cake was recorded. In Ogliastra, an elder lady still retains the knowledge regarding the collections, maintenance and utilization of acorns for preparing a cake, a knowledge once common and now quite completely disappeared. The present paper reports on the culture associated to acorn used as a food for humans.</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue></record></records></xml>
