2009 Vine Phenology
University of Vermont (UVM) Vineyard
UVM Horticulture Research Center, South Burlington, VT

The UVM Vineyard is a research/demonstration site that has eight winegrape and eight table grape varieties.   The winegrape varieties are part of a national evaluation of winegrape varieties (a joint USDA NE1020 Project with the Viticulture Consortium-East),  an EPA Pesticide Environmental Stewardship Program Project, and a UVM Agric. Exp. Station Research Project.   It was planted in 2007, using a randomized complete block experimental design of six blocks with four-vine plots of each winegrape variety per block.  The vines are being trained to a high-wire cordon system.  The soil is a well-drained Windsor loamy sand; drip irrigation has been installed.  The table grape varieties are planted in two-vine plots along the perimeter of the vineyard and are there for demonstration purposes.

 

Notes on Methods:

  • Vines are individually assessed to determine what stage on the BBCH-scale the most developed bud/shoot/flower/berry is at.
    Many stages are present on a single vine at one time.
  • Only buds within the fruiting zone (8" below top wire and above on high wire cordon trellis system) are assessed.
  • Vines without buds within the fruiting zone are not included in the assessement or in calculations.
    Results shown below only include vines with growth in the fruiting zone.
  • Cultivars are planted in six four-vine (winegrape) panels or six two-vine (tablegrape) panels.
    Values assessed for individual vines within the panels are averaged, then the six panel averages are averaged to determine the mean for the cultivar.
  • NOTE: When a percent of VINES are a certain stage, the does NOT indicate that all BUDS are at that stage.
    i.e. 50% of vines at budbreak may only have 10% of buds at budbreak.
  • Tables below show percent of vines at each stage for each date that assessments were performed.
  • For more information on the BBCH-scale see http://www.bba.de/veroeff/bbch/bbcheng.pdf
