BRS Vitória Grape Phenology and Maturation Data Across Rootstocks

Two production seasons of data on the 'BRS Vitória' table grape cultivated under subtropical conditions. The study measured phenological stage durations, thermal demand in degree-days, and berry chemical properties across three rootstock types. Daniel Callili authored this research, which found total cycle periods ranging from 131 to 143 days.

Use Cases

• Modeling phenological stage durations based on rootstock type and thermal demand.
• Predicting berry maturation index and soluble solids accumulation for different grape rootstocks.
• Comparing vine precocity in early versus later growth phases across different grafting materials.

Strengths

• Data spans two full production seasons, allowing for seasonal comparison.
• Includes concrete measurements: thermal demand ranging from 1,545 to 1,725 degree-days and total cycle periods from 131 to 143 days.
• Measures multiple berry maturation metrics: titratable acidity, pH, soluble solids, and maturation index.

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• Last update date is unknown; freshness unverified.
• Data may reflect geographic and climatic bias inherent to the specific subtropical study conditions.
