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...

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...

Water partitioning and respiration activity of dormant grape buds

Creator:

Gardea, Alfonso A.

Abstract:

Dormancy of 'Pinot Noir' grapevines was characterized. Primary buds required ca 300 cumulative chilling hours (CCH) to initiate the transition from endodormancy to ecodormancy, which occurred in mid November. Additional chilling, up to 1000 CCH, improved budbreak. Changes in bud water content were estimated by gravimetric and spectroscopic methods. Total,...
