Table grape quality from vineyard to shelf – Maties researcher investigates

SA Fruit Journal: June / July 2021

Grape quality from vineyard to shelf is under the spotlight in a new research project underway in the Robertson region. By Jorisna Bonthuys.

This is the PhD research focus of Janéne Strydom, a researcher at the Agricultural Research Council (ARC) Infruitec-Nietvoorbij and postgraduate student of horticulture at Stellenbosch University. Her study leader is Prof Kobus Hunter, a specialist scientist in viticulture, also based at the ARC Infruitec-Nietvoorbij.

Strydom’s research is funded by the South African Table Grape Industry (SATI), the ARC and the National Research Foundation (NRF).

She is focusing her efforts on investigating how Crimson Seedless grapevines react
to abiotic factors and how this reaction subsequently affects the sensory quality of the product. (The term “abiotic” refers to the non-living parts of an ecosystem that shape a vine’s growth environment, such as the climate.)

In particular, she is investigating how these vines respond to the mesoclimate
(the climate of a small area, typically an individual vineyard or hillside) and different water regimes (receiving lots of water or less of it). How do these factors affect, among other aspects, the ripeness levels of grapes?
