Inflorescence necrosis, ammonium, and evidence for ferredoxin-glutamate synthase activity in grape (Vitis vinifera L.)

Creator:

Creasy, Glen L.

Abstract:

Death of flower parts near bloom due to inflorescence necrosis (IN) is associated with high ammonium (NH₄⁺) concentration in flower clusters, shade, cool wet weather preceding bloom, and excessive vigor. Faults in NH₄⁺ assimilation are suspected to cause a rise in NH₄⁺ concentration to toxic levels in flower cluster but...

Relationships of ammonium and nitrate status with inflorescence necrosis in 'Pinot noir' grapevines

Creator:

Gu, Sanliang

Abstract:

Inflorescence necrosis (IN) is a recently described disorder in grapes characterized by partial or complete deterioration of the pedicel and rachis near bloom. Elevated levels of ammonium in the rachis are associated with the incidence of IN and hypothesized as the cause of the disorder. An incubation system with single-node...
