摘要：This paper aims to study the influence of cultivar and vermicompost (organic fertilizer) treatments on fruit quality traits (fruit weight, flesh firmness, juice pH, chromatic coordinates in CIELab system, chlorophyll fluorescence) and plant productivity on Lonicera caerulea L. The experiment was carried out between 2019 and 2020, at the Research Institute for Fruit Growing Pitesti, Romania. To achieve these, three honeysuckle cultivars ('Cera', 'Loni', and 'Kami') were treated with four fertilizer doses: 0.2, 0.3, 0.75, and 1.0 L per plant. We found that 'Cera' cultivar was characterized by fruits with the highest weight (0.67 g) and firmness (13.71 units Bareiss HPE-II-FFF), 'Kami' cultivar, had the highest total soluble solids content (17.09 °Brix), and 'Loni' was the most productive (33.33 g per plant). Compared to untreated plants, fertilization with vermicompost in a dose of 0.2 L per plant increased fruit weight by 14.81%, pH by 9.79%, and fruit production per plant by 36.65%, indicating that fertilization with vermicompost could be used in ecological honeysuckle culture technology.
