Studied plant features -height, diameter, shoot and root dry weight, and number of branches- were correlated with container dimensions. Observations on sorne practical problems in several containers and their suitability for forest plant production are given.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">CARRASCO MANZANO, I</style></author><author><style face="normal" font="default" size="100%">OCAÑA BUENO, L</style></author><author><style face="normal" font="default" size="100%">PEÑUELAS RUBIRA, J L</style></author><author><style face="normal" font="default" size="100%">DOMÍNGUEZ LERENA, S</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">ENSAYO DE TRATAMIENTOS HERBICIDAS EN CULTIVO DE TRES ESPECIES FORESTALES (P. halepensis, P. nigra y Q. ilex) 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%">Herbicides</style></keyword><keyword><style  face="normal" font="default" size="100%">Nursery</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><pub-location><style face="normal" font="default" size="100%">Pamplona</style></pub-location><pages><style face="normal" font="default" size="100%">111-116</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Weeds are one of the problems which more economic costs originates in forest nurseries due to their effect on crop growth. In spite of this, the effect of weeds on forest seedlings and their control in the nursery have not been much studied. In this study we have analysed the ability of five herbicides (Pendimethalin, Propizamide, Napropamide, Oxyflurofen and Simazine) in controlling weeds and their possible harmful effect on two Pinus species (Pinus halepensis, P. nigra ) and Quercus ilex in the nursery. Pendimethalin and Propizamide damaged seriously all tree species while Napropamide and Oxyflourfen did not produce any harmful effect and did not control effectively weeds. Simazine controlled weeds not affecting tree seedlings although it had to be applied periodically to mantain its effect on weeds.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">OCAÑA BUENO, L</style></author><author><style face="normal" font="default" size="100%">DOMÍNGUEZ LERENA, S</style></author><author><style face="normal" font="default" size="100%">CARRASCO MANZANO, I</style></author><author><style face="normal" font="default" size="100%">PEÑUELAS RUBIRA, J L</style></author><author><style face="normal" font="default" size="100%">HERRERO SIERRA, N</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">INFLUENCIA DEL TAMAÑO DE LA SEMILLA Y DIFERENTES DOSIS DE FERTILIZACION SOBRE EL CRECIMIENTO Y SUPERVIVENCIA EN CAMPO DE CUATRO ESPECIES FORESTALES</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%">fertilization</style></keyword><keyword><style  face="normal" font="default" size="100%">P.pinaster y P.sylvestris</style></keyword><keyword><style  face="normal" font="default" size="100%">P.pinea</style></keyword><keyword><style  face="normal" font="default" size="100%">Q.ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">Seed size</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><pages><style face="normal" font="default" size="100%">461-466</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The effect of different fertilization doses on the growth in nursery and the field performance were assessed in Q.ilex, P.pinea, P.pinaster and P.sylvestris, wich differ in their seed size. Growth in nursery and results in the field showed marcked differences between fertilized and unfertilized treatments. Smaller seed species are more dependent on fertilization than larger seed species.</style></abstract></record></records></xml>
