Physico-chemical characterisation of blueberry varieties

The study was carried out at the Julio Hirschhorn Experimental Station (Lat. 34º 52' S and Long. 57º 58'W, 15m asl) of the Faculty of Agricultural and Forestry Sciences of the National University of La Plata, province of Buenos Aires, Argentina in the town of Los Hornos, Partido de La Plata.the blueberry crop is composed of plots with different varieties of the genus Vaccinum corymbosum "high blueberry", in this study we worked with Blue Cuinex and Georgia Gem of normal development and without visible health problems. The plants have been grown under rainfed conditions and with minimal pruning, weed control and phytosanitary management in order to test their productive adaptability under local climatic conditions. The orchard is managed in rows planted at a distance of 3 x 1m, i.e. a density of 3333 plants/ha, under rainfed conditions. During the 2016/2017 campaign on 27 plants of each variety distributed in random blocks, the following were determined: production per plant (Kg/pl), berry weight (gr), canopy projection (m2), canopy height, pH, total soluble solids (TSS), anthocyanin content and total acidity.
