Berry Size and Qualitative Characteristics of Vitis vinifera L. cv. Syrah

2016

The effect of variation in berry size on berry composition was studied in irrigated Syrah/R99 grapevines, located in a temperate area of South Africa. Berries from 45 clusters, sampled from both sides of the canopy (east and west), were weighed to create four categories: 1. less or equal to 1.5 g; 2. between 1.51 g and 2.00 g; 3. between 2.01 g and 2.50 g; 4. more than 2.50 g. Berry physical characteristics were determined and total anthocyanins and seed flavonoids were analysed by spectrophotometry and anthocyanin profiles by HPLC. The ratio of skin weight:berry weight did not change with increasing berry size, but the ratio of seed weight:berry weight increased. For total anthocyanins, va…

Berries variability: causes and effects on the quality of ‘Cabernet Sauvignon’

2018

In this study the objective was to investigate if differences in berry size (within a population of berries from different bunches) and flowering process would lead to differences in qualitative parameters and berries variability. The trial was conducted during the 2009 vegetative season at an irrigated ‘Cabernet Sauvignon’/1103 P vineyard. At the beginning of flowering, for 100 inflorescences, all open flowers were marked by red ink while 5 days later, closed flowers were marked by black ink. Open and closed flower distribution was investigated along the rachis. At pea size, 20 marked bunches were sampled. The diameter and weight of all berries was measured and Gaussian distribution was pe…
