Vegetative growth of apricot (P. armeniaca L.) cultivars and rootstocks

Abstract

The continuous innovation in point of apricot cultivars and rootstocks requires comparative trials, which can be evaluated by precise measurements. An experiment is established, initiated from the recent trends. 15 scion cultivars were budded on 6 different rootstock cultivars. Apricot seedling, Montclar, Myrobalan 29C, Wavit, Rootpack R and Fehér besztercei were used as rootstock. Scions included traditional Hungarian cultivars (Gönci Magyar kajszi, Ceglédi óriás, Ceglédi szilárd, Pannónia), naturalized cultivars (Bergeron, Roxana) and modern cultivars too (Goldrich, Tardif de Valence, LadyCot, FlavorCot, PinkCot, Spring Blush). The experiment was settled at spring of 2018, with 3 × 5 m spacing. Sprouting was 98%, the deficiency was originated only from fawn damage. The main effect of the different rootstocks can be observed in the growth habit of scions, meanwhile the scion cultivar also has a moderate impact.
