Project description
Leaf water potential thresholds of grapevines have been published on a few occasions in the last five years. These thresholds however differed greatly as different cultivars was reported on and research were done under vastly different conditions (rootstocks, atmospheric conditions, soil types, etc.). The main objective of the proposed trial would be to investigate how the leaf water potential differ of different cultivar scions and what effect different rootstocks would have under similar climatic conditions and soil type and water status in order to adapt published plant water potential threshold tables for more accurate irrigation scheduling.
