Abstract
The responses of ‘Flopria’ apricot to the propagation techniques of micropropagation (M) and graft (G) were compared through the assessment of some vegetative and reproductive traits.
Both the M and G trees were planted (5×3 m distance) in 2011 at a private farm in southern Italy and trained to open vase.
At 2 and 4 years after planting, the trunk diameter, tree height, number of floral buds, flowers, fruit-set and the presence of spiny spurs were recorded.
At 2015 harvest, fruit size, °Brix and fruit firmness were determined.
Trunk diameter and fruit quality traits did not differ between treatments, while the numbers of floral buds, flowers and fruit-set of M trees were on average ~65% of those of G trees.
Tree height and the presence of spiny spurs on basal branches were higher in M trees.
The paper discusses the overall higher presence of juvenile traits in M trees compared to G trees.
