Abstract
Rendering valuable - via processing – of plant raw-materials is a permanent aim of research in the field of horticulture, being generated by the necessity for a balanced range of foodstuffs all the year round (Gherghi, 1999). Demand for food preserves on market set the scientific research the task of finding solutions for the improvement of processing technologies as well as the introduction – in the process of valuable rendering – of certain new fruit varieties of high organoleptic, nutritional and technological qualities superior to the extant ones (Beceanu, D., A. Chira 2003). As for now, programmes of apple research include objectives referring to obtaining varieties for processing and identifying cultivars meeting the demands of processing entirely. The main objectives pursued by the researches pertaining to this study are materialized in the following aspect the study of performances of two autumn apple varieties and three winter ones, to be found in the variety collection of the USAMV, regarding nine characteristics conferring high fitness for juice extraction. For both autumn-apple varieties and the winter ones, testing has been carried out within comparative cultures set in blocks following a linear model, each including 15 to 25 trees. Thus, per total parcel-repeats, of each variant 36 to 60 trees were checked for: fruit yield, fruit weight, fruit volume, dry-matter, sugar content, total acidity, vitamin C, juice yield, and juice output (Table 1).
