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...

Measuring Combine Facilitated Transport of Italian Ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] Seed During Wheat Harvest and Preventing the Distribution of Italian Ryegrass Seed During Harvest by Removal or Destruction of Chaff

Creator:: Roerig, Kyle C.
Abstract:: Italian ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] resistant to multiple herbicide sites of action continues to limit winter wheat production in western Oregon. In addition to impacting wheat production, multiple resistant Italian ryegrass may threaten the market for annual ryegrass seed for cover crops if wheat fields with...

Strategies for machine harvesting of mature coffee (Coffea arabica L.) fruits

Creator:: Tongumpai, Peeradet
Abstract:: Greenhouse and field grown coffee plants were used to study the synchronization of flowering and fruiting. The purpose of these studies was to develop methods of improving the selective harvesting of mature coffee fruits by machine. The studies were divided into 4 parts: 1) Synchronization of flowering, 2) Synchronization of...

Spectroscopy of biophysical, physiological and pathological responses of plant germplasm

Creator:: Li, Ning
Abstract:: Imaging spectra of plant tissues yield considerable potential and useful information for basic studies and agriculture practice. We constructed an imaging spectrophotometer with spectral range from 400 nm to 1100 nm, which was used to study various physiological events of plant germplasm: location of bundle sheath and mesophyll cells in...

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...

New sources and linked AFLP markers for Eastern filbert blight resistance in hazelnut

Creator:: Chen, Honglin
Abstract:: Eastern filbert blight (EFB), caused by Anisogramma anomala (Peck) E. Miiller, is a devastating disease to orchards of the European hazelnut (Corylus avellana L.) in the Willamette Valley, Oregon. Host resistance is the most desirable means of disease control. Fifty-eight hazelnut accessions, including European cultivars and interspecific hybrids were evaluated...

Cellular events conditioned by the Np gene of Pisum sativum L. in response to reduced UV light, weevil oviposition, and bruchins

Creator:: Ketter, Ann P.
Abstract:: In Pisum, the Np gene conditions two mitotic responses - to bruchid weevil oviposition on the pod and to reduced UV light. Oviposition by the weevil results in tumorous or neoplastic growth under the egg. Biochemically active compounds, called bruchins, were isolated from two bruchid insects (Doss et al, 2000)....

Nitrogen use in container-grown woody ornamentals

Creator:: Sandrock, David Ray, 1971-
Abstract:: Lasting, effective solutions to nitrogen (N) loss from container nurseries must address layers of complexity ranging in scale from whole system nursery management to gene expression. Group-based On-site Active Learning (GOAL) was developed to aid nursery managers and related stakeholders (e.g. neighbors, policy makers, regulating agencies, researchers) in developing a...

Fingerprinting and genetic stability of Rubus using molecular markers

Creator:: Castillo, Nina Rosa F.
Abstract:: Two studies used DNA markers to assess their usefulness in germplasm identification and evaluation of genetic stability in four cryopreserved Rubus accessions that were stored for over 10 years in liquid nitrogen. In the first study, 12 robust Simple Sequence Repeat (SSR) markers were developed from two microsatellite-enriched libraries of...
