Water relations in red and white clover seed crops

Creator:: Oliva, Ruben N.
Abstract:: Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...

Effect of nitrogen and water stresses during tillering and grain- filling in wheat

Creator:: Ashraf, Muhammad, 1952-
Abstract:: The CERES-Wheat Crop Growth and Development model treats temperature, nitrogen and water stresses as limiting factors. For each day the model calculates a stress index for temperature, N and water, compares the magnitude of the indices, and then adjusts the calculated daily potential growth using the index of the most...

New male sterile mutant in cucumber (Cucumis sativus L.) : inheritance, genetic relationship to other mutants and sex types, and response to chemical and environmental factors

Creator:: Zhang, Qi (Qi Qun), 1956-
Abstract:: A new male sterile (MS) mutant was found in 1988 in an inbred line of cucumber (Cucumis sativus L.) in the greenhouse of Sunseeds Company. The mutant is characterized by normal corolla in both male and female flowers, normal fertility in the female, and absence of pollen in otherwise normal-appearing...

Techniques for studying the effects of various cropping systems on the germination of buried weed seeds

Creator:: Thorsen, Jack Arlen
Abstract:: The study of the effects of cropping systems on buried weed seed is very costly. Most of the experiments of this nature were conducted prior to the introduction of herbicides. New techniques, material and methods are needed and could result in more research in this area of study. A polyester...

Apple mycorrhizae and their effects on growth and nutrient concentration in apple seedlings grown in two soils with varied levels of P

Creator:: Geddeda, Yosef Ibrahim
Abstract:: A study was conducted to characterize the vesicular-arbuscular (VA) fungi of apples grown in Oregon. Using roots and soil from apple orchards as inoculae, six different fungal species were found in pot cultures: Gigaspora margarita Becker and Hall, Glomus fasciculatum (Thaxter sensu Gerdemann) Gerd. and Trappe, Glomus mosseae (Nicol. and...

Establishment of Kura clover for seed with wheat intercrops

Creator:: Snelling, John P.
Abstract:: Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and has low seed yields the year after establishment. Intercropping a cereal grain during clover seed field establishment could provide additional revenue to seed growers, provided that intercropping did not jeopardize future clover seed yields. Factorial combinations of spring- and...

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...
