Influenza della climatizzazione per microaspersione sovrachioma sulla curva di maturazione di fragola rifiorente

Temperature increase involves air-conditioning techniques to preserve production standards, also in the mountain strawberry fields, where the climate is usually favourable to summer crop. The cultivation technique shifting from junebearing cvs, with a short vegeto-productive cycle, to everbearing cvs, with a long-lasting one, extends the probability to run up against these adverse conditions. A over canopy microsprinkler irrigation system was set up in rain shield high tunnels of soilless everbearing strawberry orchard, located in Trentino region at 1.100 m a.s.l., to determine the effect on crop factors. Monitoring the microclimate showed a considerable effect on thermo-hygrometric parameters. This resulted in a significant alteration of the vegeto-reproductive plant development and, subsequently, of the maturation curves. Flower morphogenetic extent significantly changed between thesis and the yield trend showed a similar pattern but shifted with a progressive time delay
