Auxin-mediated relationships between apple plants and root inhabiting fungi: impact on root pathogens and potentialities of growth-promoting populations. Organic Eprints
Manici, L.; Kelderer, M.; Caputo, F.; Mazzola, M..
This study aimed to elucidate the relationship between plant hosts and root-colonizing fungi recovered from apple orchard soils that had been replanted over multiple generations. Functional relationships of three groups of filamentous fungi (Ceratobasidium sp., Cylindrocarpon-like group and Fusarium acuminatum) with apple rootstocks were evaluated in plant growth bioassays. The Cylindrocarpon-like group and Ceratobasidium sp. showed a relationship with the host plant varying from pathogenic to commensal through to mutualistic for the latter group, while that of F. acuminatum tended to be mutualistic. Seven fungal isolates of each group, which induced the highest plant growth in bioassays, were evaluated for auxin (IAA) and gibberellin (GA3 and GA4)...

Benefits from cover crops based on plant-microbial interaction Organic Eprints
Manici , L.M.; Kelderer, M.; Caputo, F.; De Luca Picione , F.; Topp, A..
This study was performed on the impact of two different cover crops (cereal and legume) on composition of root fungal endophytes and rhizospheric bacterial communities as a function of crop health in replanted apple orchards.

ENDOPHYTIC FUNGAL POPULATIONS ACTING ON SOIL SUPPRESSIVENESS IN FRUIT TREE ORCHARDS Organic Eprints
Manici, L.M.; Kelderer, Markus; Caputo, F.; Nicoletti , F.; Topp , A..
The aim of the present study was i) to identify the soil inhabiting endophytic fungal populations having beneficial impact on crop health; ii) to identify the biological processes responsible of this functional effect. Activity was performed on fungal populations extracted from the microbial population of soil samples coming from three apple growing areas of Europe. Functionalities of Fusarium oxysporum and binucleate Rhizoctonia observed in this study are two small examples of soil biological resources that could be exploited in organic agriculture for developing innovative cropping practices.

Impact of cover crop in pre-plant of apple orchards: relationship between crop health, root inhabiting fungi and rhizospheric bacteria Organic Eprints
Manici, L.; Kelderer, M.; Caputo, F.; Nicoletti , F.; De Luca Picione , F.; Topp , A.R.
Manici, L. M., Kelderer, M., Caputo, F., Nicoletti, F., De Luca Picione, F. and Topp A. R. 2015. Replant disease of fruit tree orchards has a multifactorial etiology, mainly due to the decline in soil biodiversity along with an increase in root rot pathogens, which can be principally countered with appropriate cropping practices. Therefore, a study on the impact of cover crops on plant health of young fruit trees in long-term orchards was performed. Bioassays were performed over two consecutive growing cycles using soil from a multigeneration apple orchard affected by replant disease. First, a cycle was performed with three cover crops (alfalfa, barley, marigold) and apple rootstock plantlets; at the end, the above-ground part of the plant was removed...

Relationship between root-endophytic microbial communities and replant disease in specialized apple growing areas in Europe Organic Eprints
Manici, L.; Kelderer, Markus; Franke-Whittle , I-H; Rühmer , T.; Baab , G.; Nicoletti , F.; Caputo, F.; Topp, A.; Insam , H.; Naef, A..
Apple replant disorders are one of the causes of the downward trend of land planted with apple orchards in Central Europe. A specific transnational survey was thus conducted on apple root associated microorganisms, aimed at increasing the knowledge regarding crop management to counteract this tendency.

Manici, L.; Kelderer, Markus; Franke-Whittle , I-H; Rühmer , T.; Baab , G.; Nicoletti , F.; Caputo, F.; Topp, A.; Insam , H.; Naef, A..
Apple replant disorders are one of the causes of the downward trend of land planted with apple orchards in Central Europe. A specific transnational survey was thus conducted on apple root associated microorganisms, aimed at increasing the knowledge regarding crop management to counteract this tendency. Soil health was evaluated using a bioassay test with root cuttings of the clonal M9 rootstock, one of the most commonly used rootstocks in Europe. Plant growth response in replant, fallow and gamma ray-sterilized soil was evaluated using soil samples taken from nine orchards selected (three per country) from specialized apple growing areas of Germany, Austria and Italy. Plant growth significantly differed between treatments but not between countries. Root...

Replant problems in South Tyrol: role of fungal pathogens and microbial populations in conventional and organic apple orchards Organic Eprints
Manici, L. M.; Kelderer, M.; Erschbaumer, G.; Caputo, F.; Babini, V.; Casera, C..
South Tyrol, the main Italian apple growing area, is characterised by an highly intensive soil cultivation. Previous investigations shows the existence of replant disorders although it has not been evaluated which are the main causes. A survey has been carried out in this area with two main aims I) to evaluate the role of soil borne pathogens in apple replant disease and II) to evaluate the effect of soil management toward soil borne pathogens causing replant diseases. The experimental sites were chosen in order to obtain three couples of contiguous conventional and organic apple orchards. Soil sickness test with young apple plants gave a significant growth reduction in all soil samples if compared to a peat control. Among all root colonising fungi...

Rhizospheric changes of fungal and bacterial communities in relation to soil health of multi-generation apple orchards Organic Eprints
Caputo, F.; Nicoletti , F.; De Luca Picione , F.; Manici, L..
The study focused on changes of rhizosphere microbial communities in apple trees in long-term replanted orchards of Central Europe, aiming at developing cropping practices to mitigate replant problems. It started from the evidence of a previous study which showed that a slight modification of root-colonizing fungal communities was responsible for a great increase of plant growth in soil samples which had previously been subjected to a gamma-irradiation cycle (25 kGy for 8 h), as compared to that observed in the corresponding untreated native soils. The study was performed on rhizospheric soil from nine multi-generation apple orchards after a plant growth assay with M9 rootstock plantlets. PCR-DGGE analysis of soil DNA was performed to evaluate fungal and...
