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...

Double-stranded RNA isolated from grapevine affected by grapevine stem-pitting disease

Creator:: Walter, Michael H.
Abstract:: Nucleic acid extracted from dormant cane phloem of grapevines affected by grapevine stem-pitting disease (SP) formed a high molecular weight (MW) band on 1.0% and 0.8% agarose gels. The band was unique to diseased vines. Other bands appeared from samples of both diseased and virus-free vines, but did not associate...

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...

How to reduce the risk of pesticide resistance in winegrape pests in Oregon [2008]

Creator:: Kaiser, Clive, Pscheidt, Jay W., Walton, Vaughn M., and Skinkis, Patricia A.
Abstract:: Pesticides, including insecticides, acaricides, fungicides, bactericides, and herbicides are essential for maintaining healthy grape crops with reliable yields and quality. In many instances, pesticides have become less effective as target organisms have developed resistance. The first record of resistance dates to 1897, when orchardists began having problems controlling San Jose...
