RESUMEN
La micropropagación mediante cultivo in vitro de plantas permite la producción a gran escala de individuos genéticamente idénticos al material de partida. Las especies leñosas tienen dificultades en la etapa de aclimatación por la lentitud que presentan en el desarrollo de respuestas fisiológicas y morfológicas a los cambios de ambiente. El éxito final de la propagación in vitro depende de la capacidad de transferencia de las plantas desde el laboratorio a las condiciones de invernáculo. Una de las herramientas para contrarrestar las pérdidas durante la aclimatación, es la utilización de hongos micorrízicos arbusculares (HMA), que establecen asociaciones simbióticas mutualistas no específicas con el 90 % de las plantas vasculares. Los HMA, por su acción como agentes de biorregulación del crecimiento, biofertilizantes o biocontrol, han tenido especial atención en el manejo y propagación de las plantas frutícolas. En este trabajo se presentan los efectos de la inoculación con HMA en el inicio de la aclimatación. Para la micorrización se empleó un solo tipo de inóculo de HMA sobre dos portainjertos de manzano: un clon de M9 y otro de la serie Cornell-Geneva (RN29 y Geneva®41, respectivamente) en tres sustratos diferentes. Los plantines inoculados con micorrizas presentaron mayor expansión de sus hojas, mayor diámetro y mayor altura, respecto al control, mostrando diferencias significativas. La aclimatación se redujo de 60 a 40 días. La incorporación de este tipo de tecnología, podría generar beneficios orientados a un manejo sustentable de la producción de plantas con menor uso de agroquímicos.

ABSTRACT
Micropropagation through in vitro plant cultivation allows large-scale production of identical individuals genetically to the starting material. Woody species have difficulties in the acclimatization stage due to their slowness in the development of physiological response to environmental changes. The ultimate success of in vitro propagation depends on the capacity of plants to adapt in the moment of transfering from the laboratory to the greenhouse conditions. One of the tools to offset losses during acclimatization is the use of arbuscular mycorrhizal fungi (AMF), which sets mutualistic symbiotic associations unspecific with 90 % of vascular plants. AMF, because of their action as agents of growth bioregulation as bio-fertilizers or biocontrollers have received special attention in handling and propagation of fruit plants. In this work the effects of inoculation with AMF at the start of acclimatization are presented to mycorrhization. Inoculation with one type of AMF over two rootstocks of apple was done in a clone of M9 and one rootstock of the Cornell-Geneva series (RN29 and Geneva®41 respectively) set in three different substrates. Seedlings inoculated with AMF when compared to the control, presented further expansion of their leaves, bigger diameter and greater height, all significantly different. Acclimatization period was reduced from 60 to 40 days. The incorporation of this type of technologies could generate a more sustainable management of plant production with less use of agrochemicals.

Abstract:
Pear decline (PD) caused by 'Candidatus Phytoplasma pyri' (subgroup 16SrX-C of apple proliferation or AP group of phytoplasmas) is an important pear disease (Pyrus communis L.). Pear production in Uruguay is based on 'Williams' plants initially grafted on quince that are planted deep and thus transformed into scion-rooted trees. Less vigorous rootstocks like Pyrus spp. and quinces that could be more susceptible to decline are beginning to be used for precocity. Surveys were conducted on plants grafted on different rootstocks to know if PD was present in the pear growing area of Uruguay (southern part near Montevideo city) by searching for premature reddening, upward rolling of leaves and decline. Phytoplasmas were observed in 35 of 70 samples using the DAPI (4',6-diamidino-2-fenilindol) staining test. Ten positive and 10 negative samples were analyzed by polymerase chain reaction (PCR) assay using AP-group specific primers f01/r01. A 930 bp amplicon was obtained only from all DAPI positive samples. The f01/r01 amplicon was sequenced and showed 100% identity with the 16S rRNA gene sequence of PD phytoplasma in the NCBI database. A relationship was observed between phytoplasma detection, reddening, psylla infestation and premature leaf fall in this survey in 1995. Presence of PD-symptoms and phytoplasma detection by PCR were also evaluated in an experiment where 20 pear scion/rootstock combinations were compared during 2005-2011. Plants of self-rooted 'Williams' or grafted onto OH×F 40 and OH×F 69 stocks showed less early reddening and leaf fall than plants grafted onto quince rootstocks. Phytoplasma detection in this trial varied among seasons and was not associated with the presence of symptoms. Phytoplasmas were detected in pear psylla insects during the whole 2009-2011 seasons in four pear orchards. An association between the effectiveness of psylla control, phytoplasma detection and early reddening and leaf fall was found in an experiment with traditional 'Williams' self-rooted plants in 2011. These results indicate the presence of PD phytoplasma in Uruguayan pear orchards and in psylla insects during the whole season.
