- Grapevine Buds: Origin, Development, and Fruiting Potential
In this lecture, Dr. Goffinet describes in detail the origin and seasonal development of grapevine buds. Bud formation is a two year process, with next years' buds and tissues starting to develop by bloom. During the season, internal tissues, such as the first several leaf nodes, cluster and tendril primordia, are developed up to the 15th node by leaf fall and dormancy. Grapevine florets develop into flowers at the end of the dormant season, culminating in anthesis. Cluster number is already determined by bloom, and influenced by reserves, exposure and competition from other physiological sinks. Heat unit accumulation drives floral development. Managing buds to optimize fruitfulness, exposure, and retaining the best buds is a major objective of vine management.
This is second in a series of three one-hour lectures delivered at the 63rd annual conference of the American Society for Enology and Viticulture in 2011.
The series started with:
I. Grapevine Vegetative Structure and Whole-vine Vascular Integration
The series continues with:
III. Grapevine Tissue and Organ Injury, Accomodations to Injury, and Vine Repair Strategies
These lectures provide a comprehensive and detailed view of grapevine anatomy, annual vine development, and response to injury based on Dr. Goffinet’s 30+ year career as a botanist at Cornell AgriTech.
