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...

Influence of post-harvest burning, thinning, shading and residue management on the subsequent growth and seed yield of Festuca rubra L.

Creator:: Kim, Syng Chul
Abstract:: The effects of post-harvest burning of red fescue on production of shoots, roots and inflorescences as well as seed yield were determined at the clonal and community level by comparing fescue plants in a burned area with those in unburned plots within the same field. Studies were also conducted to...

Acid hydrolases and seed shriveling in triticale seeds

Creator:: Lin, Tsan-piao
Abstract:: The tissue and substrate degradational enzymes, acid hydrolases, in endosperm were studied in order to discern the mechanism of seed shriveling in triticale (XTriticosecale Wittmack). Acid hydrolases in crude extract of 7-week-old developing endosperm of 2 lines each of triticale with shriveled (6TB,JZBS) and plump seeds (6TA, RBP) were successfully...
