The experiments were carried out during three vegetation seasons (2014 – 2016) on Cardinal grape variety grown on pergola training system, with a planting distance of 2.5 m x 2.5 m, in Gevgelija-Valandovo vine growing region, the Republic of Macedonia. After the blooming phenophase, the number of bunches (crop load) was reduced. Three bunch thinning variants were applied: V1 (thinning to 3 bunches/m2 ), V2 (thinning to 4 bunches/m2 ) and V3 (thinning to 5 bunches/m2 ). They were then compared with the standard (ST) where no thinning of bunches was applied. Research results show that bunch load in Cardinal variety has a significant impact on bunch and berry mass, transportability, maturation dynamics and packed grape quantity and that the V1 variant, with the lowest bunch density per m 2 , has the largest individual bunch and berry mass (502.3 g and 8.83 g respectively), while the ST variant yielded the smallest bunch and berry mass (451.7 g and 7.93 g respectively). We got similar results on grape transportability marked by berry firmness and berry adherence strength. The largest quantity of total harvested grapes was obtained in the V3 (2.22 kg/m2 ) and ST (2.19 kg/m2 ) variants, while the smallest quantity of total harvested grapes (1.47 kg/m2 ) was obtained in the V1 variant. The largest quantity of packed grapes (1.87 kg/m2 ) was obtained in the V2 variant, and the smallest in the V1 variant (1.44 kg/m2 ). | URI: | http://hdl.handle.net/20.500.12188/33345 | DOI: | 10.17707/agricultforest.67.4.10 |
