Abstract
In this study, we investigated the effect of pH on plant growth and mineral content in Vitis vinifera L. ‘Sultani Çekirdeksiz’, and Kober 5BB, and 41B rootstocks.
Plants were grown in media with pH 4.5, 7.0 and 8.5 and the effect of different pH on fresh or dry root weight and fresh or dry shoot weight and mineral content were analyzed.
While the effect of different pH on the root length of the 5BB was significant, no significant effect was observed in the 41B rootstock and ‘Sultani Çekirdeksiz’. The effect of pH on fresh root weight was significant in all plants, and the fresh root weight significantly decreased with increasing pH. The shoot length and leaf area of 5BB and ‘Sultani Çekirdeksiz’ were significantly affected by different pH values, and as pH increased, shoot length and leaf area decreased.
Overall, grapevine cultivars were adversely affected by high pH and this effect was more pronounced in shoot development than in root development.
Macro nutrient contents were significantly affected by different pH treatments.
Despite the presence of a higher amount of Fe in the leaves of grapevine cultivars grown in the soils with pH 8.5, they showed symptoms due to iron deficiency.
The effect of pH on Zn contents in leaves was observed only in 5BB rootstock, with increasing Zn content in response to high pH.
