Ammonium Metabolism in Grapes [1993-1994]

Creator:

Creasy, Glen L. and Breen, Patrick J.

Abstract:

The connection between the fruit-set disorder Inflorescence Necrosis (IN) and high ammonium (NI14+) in affected tissues has led to an investigation of NH4+ assimilation enzymes (principally glutamine synthetase (GS) and glutamate synthase) in grape tissues. Previous work in this department has suggested that toxic levels of NH4+ build up in...

Viticultural Factors Affecting Inflorescence Necrosis and Ammonia Metabolism [1995-1996]

Creator:

Creasy, Glen L. and Breen, Patrick J.

Abstract:

Inflorescence Necrosis (IN) has been an unpredictable problem for grape growers in Oregon. The industry has seen significant losses due to this fruit set disorder in several out of the eight years since its first description in 1988, particularly in Pinot noir. Little is known of how to prevent the...
