Truffle cultivation has quickly grown in European countries and elsewhere, so a commonly shared seedling evaluation method is needed. Five evaluation methods are currently published in the literature: three are used in Spain and two in France and Italy. Although all estimate the percentage colonization by T. melanosporum mycorrhizae, they do it in different ways. Two methods also estimate total number of mycorrhizae per seedling. Most are destructive. In this work, ten batches of holm oak seedlings inoculated with T. melanosporum from two different nurseries were evaluated by means of the five methods noted above. Some similarity was detected between the percentages of T. melanosporum mycorrhizae estimated by each method but not in their ability to assess the suitability of each batch. We discuss the advantages and disadvantages for each method and suggest approaches to reach consensus within the truffle culture industry for certifying mycorrhizal colonization by T. melanosporum and seedling quality.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: 233 SPRING ST, NEW YORK, NY 10013 USA&lt;br/&gt;publisher: SPRINGER</style></notes></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%">Sánchez, S</style></author><author><style face="normal" font="default" size="100%">Gómez, E</style></author><author><style face="normal" font="default" size="100%">Martín, M</style></author><author><style face="normal" font="default" size="100%">DE MIGUEL, A M</style></author><author><style face="normal" font="default" size="100%">Urban, A</style></author><author><style face="normal" font="default" size="100%">Barriuso, J</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Experiments on the life cycle and factors affecting reproduction of Sphaerosporella brunnea provide evidence for rapid asexual propagation by conidiospores and for homothallism in an ectomycorrhizal competitor of cultivated truffle species</style></title><secondary-title><style face="normal" font="default" size="100%">Fungal Ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Conidiation</style></keyword><keyword><style  face="normal" font="default" size="100%">Controlled mycorrhization</style></keyword><keyword><style  face="normal" font="default" size="100%">Dichobotrys</style></keyword><keyword><style  face="normal" font="default" size="100%">Mycorrhized plants</style></keyword><keyword><style  face="normal" font="default" size="100%">Nurseries</style></keyword><keyword><style  face="normal" font="default" size="100%">Truffle cultivation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year></dates><volume><style face="normal" font="default" size="100%">8</style></volume><pages><style face="normal" font="default" size="100%">59-65</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Sphaerosporella brunnea is a pioneer and opportunist ectomycorrhizal species, and the most common fungal competitor in nurseries producing plants mycorrhized with Tuber species. Our objective was to learn more about its life cycle as the first step to manage its presence in greenhouses. Conidiation and formation of resting spore-like structures were found to be triggered by aeration and to be highest on CMA medium. In pot experiments S. brunnea was able to form ectomycorrhizas and ascocarps rapidly, in 2 and 3 months respectively, if substratum moisture was high. Both mycelia and conidiospores were effective sources of inoculum for mycorrhization. This species seems to be homothallic as apothecia have been obtained after inoculations with single monospore isolates. Propagation by mitospores and homothallism are poorly documented in ECM fungi, therefore these results may be of fundamental interest beyond the question of greenhouse management.</style></abstract></record></records></xml>
