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...

Evaluating the Effects of Alleyway Management on the Performance of Dry-Farmed Pinot noir Grown in Different Soils

Creator:: Lange, Mathew
Abstract:: Vineyards in Oregon’s Willamette Valley are predominately planted to perennial grass cover in the alleyways of vineyards. This grass cover is grown to increase worker and equipment traction, as well as reduce erosion and manage vine vegetative vigor. However, with increasing frequencies of drought and warming temperatures, the use of...

Inheritance of internode length, plant form and biennial habit in a cross of cabbage (Brassica oleracea L. Capitata group) x broccoli (Italica group)

Creator:: Pelofske, Peter Joseph
Abstract:: An inbred cabbage line (Brassica oleracea L. (Capitata group)) and an inbred broccoli line (B. oleracea L. (Italica group)) were crossed. F₁ progeny were vigorous annuals. Of 3,260 F₂ plants, 250 were biennials and 70 developed cabbage heads. Of these 70, 32 were annuals. Days to first visible buds of...

The nature of flower bud influence on root regeneration in the Rhododendron shoot

Creator:: Johnson, Charles Robert
Abstract:: Flower bud influence on rootability of Rhododendron shoots was assayed by rooting leaf-petiole cuttings. Monthly samples of an easy-and an intermediate-to-root cultivar showed periods of poor rooting in the latter during flower development, although both rooted similarly during bud dormancy. The decrease in rooting-potential following flower initiation and development was...

Summary of 1967 weed control research in horticultural crops [preliminary draft]

Creator:: Crabtree, Garvin
Abstract:: The following summaries of results from experimental work with herbicides in horticultural crops cover work completed in 1967. Crops included are bush snap beans, red beets, direct seeded broccoli, cucumber, summer squash, strawberries and nursery rhododendrons. In general, weather conditions were warmer and drier than usual during the 1967 growing...

Determination of α-Amylase activity and soluble starch content in normal and cork spotted D̀'Anjou' pear fruit

Creator:: Li, Shiao Jing
Abstract:: There was a linear relationship of [alpha]-amylase activity from 2 to 12 hours incubation in both freeze-dried and fresh 'd'Anjou' pear fruit tissue. Activity was greater, however, in fresh as compared with freeze-dried tissues. [alpha]-Amylase activity from both types of samples was not detected until 60 minutes incubation. After 90...

Evaluation of Rubus seed characteristics: seed coat morphology, anatomy, germination requirements and dormancy breaking

Creator:: Wada, Sugae
Abstract:: Rubus seed characteristics; seed coat morphology, anatomy, germination requirements and dormancy were studied in order to define protocols for breaking seed dormancy. Morphological analysis of the seed coat (testa) using scanning electron microscopy (SEM) included 56 seed accessions of 10 subgenera preserved in the collections of the US Department of...

Microsatellite marker development and molecular characterization in highbush blueberry (Vaccinium corymbosum L.) and Vaccinium species

Creator:: Boches, Peter
Abstract:: Pre-existing Expressed Sequence Tag (EST) libraries (1,305 sequences) and a newly constructed microsatellite-enriched genomic library (136 clones) from the V. corymbosum cultivar 'Bluecrop' were screened for unique Simple Sequence Repeat (SSR)-containing sequences. Our goal was to develop a set of robust SSR markers for use in managing the National Clonal...

Determining ploidy level and nuclear DNA content in Rubus by flow cytometry

Creator:: Meng, Rengong
Abstract:: Nuclear DNA flow cytometry was used to differentiate ploidy level and determine nuclear DNA content in Rubus. Nuclei suspensions were prepared from leaf discs of young leaves following published protocols with modifications that included: increasing the stain concentration, adding the stain after the RN ase treatment instead of adding it...
