“…It could be presumed that fungi from P. heldreichii forests are well adapted to the hard and extremely dry environmental conditions prevalent in their natural habitats, which was partly confirmed through this examination. In addition, the fungi produce abundant sporocarps, making it easy to obtain spore inoculums for large-scale application in forest nurseries (Marx et al, 1982;Tores and Honrubia, 1994;Parlade et al, 1996). Controlled mycorrhizal inoculation programs in forest nurseries have been using the Suillus spp.…”

“…Each seedling's root was cut into 2-3 cm segments, and the percentage of ectomycorrhizal short roots was assessed by counting at least 200 randomly selected short roots under the stereomicroscope (Parlade et al, 1996;Rincon et al, 2001). Grouping of the obtained results was made according to pre-set estimation ranges 1-3, as follows:…”

Mycorrhization of containerized Pinus nigra seedlings with Suillus granulatus under open field conditions

Seedling mycorrhization acts as an efficient tool for improving the quality of seedlings. In this study, the effectiveness of Suillus granulatus, originating from Pinus heldreichii forests (Montenegro), to produce containerized ectomycorrhizal seedlings of autochthonous Pinus nigra in open field conditions was investigated. Spore (10 6 , 10 7 , 10 8 ) and vegetative (1:16, 1:8, 1:4) inoculation on ectomycorrhizal formation and seedling growth were tested. Spore and vegetative inoculums of autochthonous Pisolithus arhizus were used in the same trial as additional control treatments.The utilization of vegetative and spore inoculums of autochthonous S. granulatus has proven to be an effective method of obtaining containerized ectomycorrhizal P. nigra seedlings under open field conditions after 11 months. S. granulatus spore inoculations resulted in well developed ectomycorrhiza, decreasing the growth of the P. nigra seedlings in the first growing season. Mycelial inoculations resulted in slightly developed S. granulatus ectomycorrhiza, which increased the growth of the seedlings. Therefore, it would be feasible to use spore inocula of S. granulatus, with 10 6 spores per plant, to produce ectomycorrhizal P. nigra plants on a large scale. Controlled mycorrhizal inoculation of seedlings is not a common practice in Montenegrin and Serbian nurseries; as such, the obtained results will contribute to the enhancement of nursery production of Pinus nigra and other conifers. This also could be assumed as a starting point for many further efforts and investigations with autochthonous fungal and plant material in this region.

“…The minimal level of ECM necessary to ensure seedling performance in the field has been poorly studied, and probably depends on environmental characteristics of the site of transplantation and on the fungus-tree combination used [4,34]. The spore inoculum of P. tinctorius has been successfully used in previous experiments to produce containerised Pinus species, including P. pinea [15,28,32].…”

-Spore inocula of Melanogaster ambiguus (Vittad.) Tul. & C. Tul., Pisolithus tinctorius (Pers.) Coker & Couch, Rhizopogon luteolus Fr., Rhizopogon roseolus (Corda) Th. M. Fr. and Scleroderma verrucosum (Bull.) Pers., and two substrates (a mixture of peat-vermiculite and a mixture of peat-composted pine bark) were evaluated for producing mycorrhizal Pinus pinea L. seedlings in a commercial nursery in NE Spain. Inocula of all fungi were effective to obtain containerised mycorrhizal P. pinea seedlings although seedling mycorrhization rates were reduced in the peat/pine-bark mixture. Neither inoculation nor the type of substrate modified the first-year growth of seedlings. Rhizopogon spp. increased the levels of N and P and, in general inoculation reduced the concentration of Mn in needles. Symptoms of chlorosis were detected in all seedlings growing in the peat/pine-bark mixture, probably due to nutritional deficiencies caused by the substrate high pH. Among the fungi tested, R. roseolus is proposed as the best candidate for its application in nursery inoculation programmes destined to produced containerised mycorrhizal P. pinea. , et deux substrats (un mélange de tourbe-vermiculite et un mélange de tourbe-écorce compostée de pin) ont été évalués pour produire des jeunes plants mycorhizés de Pinus pinea L. dans une pépinière commerciale au Nord-Est de l'Espagne. Les inoculums de tous les champignons ont été efficaces pour obtenir des semis mycorhizés de pin pignon en conteneur, bien que les taux de mycorhization ont diminué dans le substrat vermiculite-écorce de pin. Ni l'inoculation ni le type de substrat n'ont modifié la croissance en première année des jeunes plants. Les espèces de Rhizopogon ont augmenté les niveaux d'azote et de phosphore dans les aiguilles des plants et, en général, l'inoculation a réduit la teneur en manganèse de ces feuilles. Des symptômes de chlorose ont été détectés dans tous les plants croissant dans le substrat vermiculiteécorce de pin, probablement en raison des carences nutritionnelles provoquées par le pH élevé du substrat. Parmi les champignons étudiés, on propose R. roseolus comme le meilleur candidat pour son application dans des programmes d'inoculation en pépinière destinés à produire des plants de pin pignon mycorhizés en conteneur.Pinus pinea / substrat / mycorhization / champignons ectomycorhiziens / production des semis en pépinière
