Abstract
High-quality planting material is crucial for robust yield and desired fruit quality, serving as tangible proof of success in agriculture.
Its indispensable role is evident throughout the cultivation process, emphasizing its significance in achieving high agricultural standards.
This research comprehensively analysed the fruit quality of tissue-cultured and plants derived from traditional propagation methods of two raspberry cultivars, ‘Meeker’ and ‘Willamette’ during 2019. Fruit quality parameters were monitored during three harvest times (early, mid, and late). The analysed parameters included soluble solids content (SSC), total acids (TA), total sugars (TS), vitamin C, total phenols (TP), total anthocyanins (TAC), and antioxidative activity [DPPH-2.2-diphenyl-1-picrylhydrazyl and ABTS-2.2’-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) test]. The cultivar ‘Meeker’ stood out with superior values for SSC and TS, whereas the cultivar ‘Willamette’ exhibited higher TA, reaching a value of 1.55%. A gradual increase in TP was observed throughout the harvest, with tissue-cultured plants reaching 228.95 mg GAE (gallic acid equivalent) 100 g‑1 FW at late harvest.
In the early harvest, TAC in in vitro propagated ‘Willamette’ plants was 39.78 mg C3G 100 g‑1 FW, while the highest TP level was observed at the late harvest period, amounting to 227.73 mg GAE 100 g‑1 FW. The results from both antioxidant activity tests indicated higher values in tissue-cultured plants, emphasizing their potential significance in nutrition and health preservation.
This study highlights the potential advantages of using tissue-cultured plants for establishing commercial orchards and offers important insights into qualitative variations among plants of different origins across both raspberry cultivars.
