Abstract
The aim of this study was to promote biodiversity to achieve a stable viticultural ecosystem and to increase the quality of grapes by using autochthonous disease-resistant cultivars.
The study was carried out between 2016 and 2022 in the experimental plots of SCDVV Blaj, cultivated with six cultivars ‘Blasius’, ‘Brumăriu’, ‘Rubin’, ‘Radames’, ‘Selena’ and ‘Amurg’ homologated at SCDVV Blaj and two classical cultivars ‘Fetească regală’ and ‘Fetească neagră’. The present study focused on a combination of agroecological techniques applied/plot/cultivar: grassing between rows: natural/sown, total/partial, maintenance of vine rows by: chemical/mechanical weeding, agro-ecological practices: grass strips, flower strips, hedges, planting shrubs at the ends of each row, planting fruit trees, providing structural elements (piles of stones or wood), use of biopesticides and biological methods of pest control.
In the agroecological system, positive results are obtained over time, while restoring the predator/pest balance.
The abundance and diversity of arthropod species increases progressively in relation to the increasing area and heterogeneity of the wine-growing landscape in and around farms (semi-natural habitats). The agroecological cropping system had a positive effect on the quality of grapes, contributing to the growth of phytochemical compounds products, especially in ‘Rubin’, ‘Radames’ and ‘Brumăriu’ cultivars.
The abundance of useful species population has increased exponentially due to the implementation of agroecological techniques The most important useful zoophages identified belong to the orders: Acari: Typhlodromus, Amblyseius, Phytoseiulus, Neoseiulus; Neuroptera: Chrysopidae: Chrysopa; Diptera: Syrphidae: Syrphus; Heteroptera: Anthocoridae: Orius, Anthocoris; Deraeocoris, Malacocoris; Coleoptera: Coccinellidae: Coccinella, Adalia, Adonia, Staphylinidae: Scymnus, Stethorus. The agroecological system of vine cultivation has improved the biodiversity and immunity of the studied wine ecosystems.
The results of this study indicate that the benefits of biodiversity on grape quality in terms of polyphenol UV-Vis fingerprint, depend on the grapevine cultivar.
