Research

Vine Physiology

Research activities focus on wine and juice grapes physiology under Michigan cool climate conditions. The main objective is identifying environmental, physiological and cultural factors that limit vine growth and development, fruit maturity and quality. In particular a) photosynthetic carbon assimilation and partitioning, b) effect of biotic and abiotic stress on vine yield and fruit quality, and c) natural carbon isotope discrimination. The ultimate research goal is to solve whole plant physiological problems that will optimize grape productivity and fruit quality in the field.

Viticulture

Cultural factors limiting vine growth, sustainable yield, fruit maturity and quality are the main areas of research. Canopy management, crop estimation and adjustment and vineyard mechanization are primary focus to better control cultural and physiological factors important for efficient production of high-value grapes.

Cultivar Evaluation

Michigan Grape and Wine Industry Council (MGWIC) aims to increase wine grape production up to 10,000 acres and 3 million cases of Michigan-produced wines annually by 2024. As of 2007, over 53 wineries have been established in Michigan in traditional production regions such as Northern and Southwest Michigan, and less traditional areas such as West Central, South East, Eastern and the Upper Peninsula. The successful expansion of wine grape production will depend on the possibility to grow appropriate varieties for site characteristics. Therefore variety recommendations are crucial and they are based on genetic performance tested in variety trials for Vitis vinifera and mixed species (hybrids) planted in the state of Michigan.
