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...

Girdling and shading effects on inflorescence necrosis and rachis composition of pinot noir grapevine

Creator:: Ibacache, Antonio E.
Abstract:: There are several grape disorders that reduce fruit set. One, millerandage, is from poor fertilization to produce "hen and chicken" or small seedless berries; while another, Coulure, is the failure of grape flowers to develop into berries. A third one, inflorescence necrosis (INec), is a disorder that should be in...

Facilitating plant-parasitic nematode management decisions for Washington Vitis vinifera growers : determining the spatial distribution of plant-parasitic nematodes and the host status of Vitis spp. to Meloidogyne hapla

Creator:: Howland, Amanda D.
Abstract:: A major constraint to the production of self-rooted wine grapes (Vitis vinifera) in eastern Washington is plant-parasitic nematodes. Plant-parasitic nematodes can impact grape productivity by limiting water and nutrient uptake, educing physiological changes, and extracting plant nutrients from roots, thereby reducing root biomass, plant vigor, and yield. The most commonly...
