Globe artichoke (Cynara cardunculus L. var. scolymus (L.) Fiori) is an edible herbaceous perennial plant that plays an important economic role in Mediterranean agriculture. In recent years, extensive research, which aimed to characterize the phenolic profile of the most important globe artichoke cultivars in Italy, has been conducted. However, very little information is available on the phenolic composition of cultivars traditionally grown in Spain. In this work, six cultivars (‘Opal’, ‘Symphony’, ‘Concerto’, ‘Madrigal’, ‘Blanca de Tudela’ and ‘A-106’) cultured in Spain were characterized according to their phenolic content. The phenolic profile differed between cultivars, and also between flower parts. The major phenolic compound in all the different cultivars was chlorogenic acid. Of the six studied cultivars, ‘Madrigal’ had the highest phenolic content.
The influence of two rootstocks (Prunus cerasifera Ehrh. and Prunus tomentosa Thunb.) on growth, yield and fruit quality of five plum cultivars: 'Herman', 'Opal', 'Cacanska Rana', 'Cacanska Lepotica' and 'Dąbrowicka Prune' was estimated. Seven years after planting, the trees of all the considered cultivars grew more vigorously on P. cerasifera rootstock than the trees on P. tomentosa. The highest yields were harvested from the trees 'Cacanska Lepotica' grafted on P. cerasifera. Productivity of all the cultivars of plum trees on P. tomentosa rootstock was higher than of these grafted on P. cerasifera seedling. The considered rootstocks had no influence on fruit weight of the investigated plum cultivars. 'Cacanska Rana' trees produced the biggest fruit, whereas the smallest were harvested from 'Dąbrowicka Prune' trees.
