2019-2020 data from a dendroecological study on 'Chardonnay' grapevine trunks infected by the Flavescence dorée phytoplasma in Origlio, Switzerland. The dataset includes measurements of xylem ring widths and descriptions of phloem anomalies, analyzing the impact of disease and drought stress. It was collected by researchers using cellSens software and analyzed within R, and published via ENVIDAT.
Use Cases
- Modeling the effect of Flavescence dorée infection on xylem ring width reduction.
- Comparing the relative impact of phytoplasma infection versus drought stress (SPEI index) on trunk growth.
- Analyzing correlations between infection status and specific phloem anatomical anomalies.
- Training classifiers to identify disease impact from ring width patterns and phloem structure data.
Strengths
- Data covers two consecutive growing seasons (2019-2020).
- Study isolates and compares effects of two distinct stressors: phytoplasma infection and drought.
Limitations
- Sample size is unknown and likely limited to a single vineyard location.
- Geographic scope is restricted to southern Switzerland (Origlio).
Provenance
- Source
- ENVIDAT via NASA Earthdata.
