Plant density was 70 plants/ha (1 ha = 10,000 m<sup>2</sup>) in PF-V and 50 plants/ha in EG. Fruit availability (D<sub>F</sub>) in fresh fruits (FF) was 4.39 kg (PF-V) and 3.10 kg (EG) during March, and decreased during June. Ascorbic acid in FF increased during ripening period, peaking on late April, early May, and diminished 75% - 85% in dried fruits. Total soluble solids in FF ranged from 32.55 to 55.20 °Brix. Elements Ba, Ca, Fe, K, Zn and Cu, determined by inductively coupled plasma optical emission spectrometry (ICP-OES), were significant for human health. Dried fruits maintain a high level of ascorbic acid, a characteristic added to content of mineral elements, particularly calcium content, providing an important nutritional value to R. rubiginosa rose hips.展开更多
