The acorns were collected in Malpica do Tejo holm oak stands, after fruit repining. Treatments included naked root plant production in normal nursery soil and plant production with different other methods: two different containers (plastic bag and plastic pot) with five different media composition (pine bark, peat, normal nursery soil, pine bark with perlite (1:1 v/v) and peat with perlite (1:1 v/v). The number of germinated seeds (G) per treatment and block was first recorded by the end of June and afterwards three times, every three weeks. Last time data was recorded, the following parameters were included: diameter (D) at soil level, height (H) and the leaf area (A), per plant. Percent of germination was better in every treatment using plastic pots, whatever the media used, and the worst results were achieved with the plastic bag/peat and naked root methods. On the other hand, the use of the plastic bag promoted plant loss, avoided with plastic pots. The best-scored treatments for the average plant diameter (D) were the pot/peat (3,26 mm) and bag/pine bark (2,92 mm) methods, and the bag/nursery soil produced the worst result (2,4 mm). The best/worst result in the mean height for plant (H), was obtained with the naked root (10,5 cm)/plastic pot with nursery soil (5,9 cm) method. The leaf area per plant (A) was 52 cm2 for the naked root method, higher then the value of this parameter in every other treatment, except in the bag/pine bark one (45 cm2 ).</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%">Martin, A</style></author><author><style face="normal" font="default" size="100%">Gallardo, J F</style></author><author><style face="normal" font="default" size="100%">Santa Regina, I</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Aboveground litter production and bioelement potential return in an evergreen oak (Quercus rotundifolia) woodland near Salamanca (Spain)</style></title><secondary-title><style face="normal" font="default" size="100%">Ann.

The woodland is located close to the city of Salamanca (central-western Spain). Litter fall occurs throughout the year, with a maximum from April to June owing to leaf fall. Mean litter production is 1.9 Mg ha-1 year-1, although variations from year to year are observed, mostly due to water stress in summer. The mean area of influence of litter fall of each tree is about 4 m outside the crown shadow and the leaf percentage (55%) over the total aboveground litter production shows that the system is mature. Tree inflorescences are found to have the highest concentration in bioelements, although the latter are mostly returned through the leaves (with the exception of K).</style></abstract></record></records></xml>
