Rootstock effect on some quality characteristics of almond cultivars ‘Troito’, ‘Marcona’ and ‘Texas’

This study was carried out in order to determine the rootstock effect on content of oil and most abundant fatty acids (oleic acid and linoleic acid), oleic acid/linoleic acid ratio, total phenolic content (TPC) and radical-scavenging activity (RSA) of almond kernels. The experimental orchard was established in 2006 in Surduk (North Serbia). Cultivars 'Troito', 'Marcona' and 'Texas' were budded (grafted) on myrabalan plum seedlings and 'GF 677'. Results revealed significant influence of rootstock on evaluated characteristics. Except content of oleic acid and oleic acid/linoleic acid ratio all other parameters had higher values when cultivars were grafted onto myrabalan plum. As expected, significant differences were also determined among studied cultivars. Except content of linoleic acid, for all other parameters the lowest values were found in 'Marcona', while highest for 'Texas'. Obtained results can be used for improving of almond quality in agroecological conditions of Serbia.
