Summary:Sitinplant, a EU-founded project, activities are presented. The project aims to transfer innovation and solve technical problems, in the fruit-growing nursery sector, improving the whole plant production cycle by micropropagation and biotisation techniques. The project introduces the combined use of mycorrhizae and antagonist bio-control microorganisms during the rootstock production process. From explants preparation to the acclimatisation phase, and inoculation, the results, obtained in two years of experiments, showed the following positive effects: i) economic: lower production costs by using biological agents instead of fungicides; ii) operational: better control of damping-off diseases, more uniform rootstock material, less time for acclimatisation; iii) environmental: minimal direct or indirect soil and ground water contamination by fungicides and reduced REI (the time after a pesticide application during which entry is restricted). Symbiosis increases the tolerance of micropropagated rootstocks to some soil pathogens and enhances plant growth. Micrografted Myrobolan 29C plants, treated with Glomus intraradices and Trichoderma harzianum, showed better physiologic and development performances, compared to control. The effects of mycorrhizae are reported on biomass evolution (and the related uptake of minerals), in micropropagated and mycorrhizated Myrobolan 29C rootstock grown in pots.
