Field trial reveals distinct effects of four rootstocks on Narince grape quality, indicating that rootstock selection optimizes fruit chemistry and phenolic content.
Key Points
To evaluate the impact of four different rootstocks on the physical, chemical, and biochemical attributes of 'Narince' wine grapes across two growing seasons.
Conducted a two-year field study during the 2020 and 2021 growing seasons in Tokat, Türkiye.
Grafted Vitis vinifera cv. Narince vines onto four distinct rootstocks: 110R, 140Ru, 41B, and 5BB.
Measured physical cluster and berry traits, chemical properties, maturity index, and biochemical total phenolic content.
Rootstock 41B resulted in the highest values for physical cluster and berry parameters.
Rootstocks 140Ru and 5BB provided the most favorable chemical properties and maturity indices.
Rootstock 5BB produced the highest biochemical total phenolic content among the evaluated rootstocks.
