Seedlings establishment of Eucalyptus grandis mycorrhizated with Pisolithus microcarpus (UFSC Pt 116) in sandy soil
O objetivo deste trabalho foi avaliar a sobreviv\ueancia e o
crescimento inicial de mudas de eucalipto micorrizadas com o fungo
ectomicorr\uedzico Pisolithus microcarpus (UFSC Pt 116), ap\uf3s
o transplante para uma \ue1rea sujeita \ue0 areniza\ue7\ue3o no
munic\uedpio de S\ue3o Francisco de Assis, RS. A \ue1rea foi
dividida em quatro blocos, cada qual com quatro tratamentos (turfa
f\ue9rtil com e sem fungo, Neossolo Quartzar\ueanico com e sem
fungo). Cada parcela foi composta por 16 mudas dispostas em quatro
linhas no espa\ue7amento de 1,5 m x 1,5 m, totalizando em cada bloco
64 mudas. Aos 90 dias ap\uf3s o plantio no campo, as mudas de
eucalipto produzidas no substrato turfa f\ue9rtil com fungo,
apresentaram uma taxa de sobreviv\ueancia de 100%, enquanto que as
produzidas em turfa f\ue9rtil sem fungo, a taxa de sobreviv\ueancia
foi de 92%. As mudas produzidas no Neossolo Quartzar\ueanico com e
sem fungo tiveram uma taxa de sobreviv\ueancia variando em torno de
98 e 89% respectivamente. As mudas produzidas com turfa e fungo
apresentaram diferen\ue7as significativas no crescimento em altura, e
di\ue2metro do caule. Conclui-se que mudas de Eucalyptus grandis
produzidas em substrato turfa f\ue9rtil e micorrizadas com o isolado
Pisolithus microcarpus (UFSC Pt 116), conseguem manter bom
estabelecimento e desenvolvimento no campo.The aim of this work was to evaluate the survival and the initial
growth of mycorrhizated eucalypts with Pisolithus microcarpus (UFSC
Pt 116) ectomycorrhizal fungus, after its transplant to area subject to
the arenization process in S\ue3o Francisco de Assis, RS. The area
was divided into four blocks, each one with four treatments (fertile
turf with and without mycorrhizae, Quartzarenic Neosoil with and
without mycorrhizae). Each parcel was composed of 16 seedlings arranged
in four lines in the spacing of 1,5 m x 1,5 m, totalizing in each block
64 seedlings. 90 days after the planting in the field, the eucaliptus
seedlings produced in turf with fungus in the fertile substratum
presented a survival rate of 100 %, whereas for those produced in
fertile turf without fingi, the survival rate was 92 %. The seedlings
produced in the Quartzarenic Neosoil with and without mycorrhizae had a
survival rate varying around 98 and 89 %, respectively. The produced
seedlings with turf and fungus showed significant differences in height
and stem diameter. This study showed that the Eucalyptus grandis
seedlings produced in substratum fertile turf and inoculated with the
Pisolithus microcarpus (UFSC Pt 116) isolated may maintain good
development and establishment in the field
