    GIARDINI IN RETE. A MODEL FOR SETTING UP DIDACTIC SOILLESS GARDENS IN SCHOOLS

    No full text
    Children’s understanding on the origin of food is nowadays affected by marketing and advertisements. Horticultural gardens in school may improve children's knowledge about nutrition and the importance of the proper use of natural resources. Simplified soilless gardens may represent an extremely effective educational tool since they allow practical descriptions of biological and biochemical processes related to plant life and growth. Furthermore, due to their independence from fertile soils, the high planting density, and the low labor requirement they represent a viable solution for most urban schools. Starting from 2012, the Giardini in Rete project aims at the introduction of a simplified soilless garden in a secondary school of Bologna to promote biodiversity and urban green landscape. In the present paper the model for setting up a didactic hydroponic vertical garden and the students' responses are addressed

    Optimal red: Blue ratio in led lighting for nutraceutical indoor horticulture

    In recent years, the interest toward the applicability of Light-Emitting Diode (LED) lights for indoor cultivation has significantly grown. The present work addressed the physiological and phytochemical plant responses to LED lights in indoor cultivation of leafy and fruit vegetable crops (namely sweet basil, Ocimum basilicum L.; and strawberry, Fragaria 7. Ananassa), with the final aim of improving both productivity and nutritional quality. Artificial light treatments were applied in a multi-sectorial growth chamber equipped with lamps with different light incidence and spectra (with red:blue ratio ranging 0.7-5.5). In all experiments, increased plant biomass, fruit yield and energy use efficiency (EUE) were associated to LED treatments, confirming the superiority of LED compared to the traditional fluorescent lamps. Interestingly, LED lighting enabled to increase antioxidant compounds and reduce nitrates content in basil leaves. A spectral red:blue ratio of 0.7 was necessary for proper plant development and improved nutraceutical properties in both crop
