Physical characteristics of crownvetch (Coronilla varia L.) seeds associated with viability and hardseededness

Creator:: Garay, Adriel Edgardo
Abstract:: The use of crownvetch (Coronilla varia L.) as a forage crop might be increased considerably if seed with low hard seed content could be made available at reasonable cost. Since mechanical scarification damages a large percentage of crownvetch seeds, this study was initiated to find other ways of reducing hardseededness....

Osmotic stress vigor test for wheat seed

Creator:: Currans, Sean
Abstract:: Seed vigor tests have been developed to evaluate the relative ability of seed lots to produce stands of seedlings in the field. Some workers have suggested the possibility of differentiating vigor levels by germinating seeds under osmotic stress, but have not conducted field trials to evaluate the usefulness of the...

Spring establishment of orchardgrass and tall fescue seed crops with cereal companion crops

Creator:: Chastain, Thomas G.
Abstract:: Orchardgrass and tall fescue seed crops are commonly springplanted in Oregon, but do not produce a marketable crop during the first growing season. Establishing orchardgrass and tall fescue with cereal companion crops would provide income during the seeding year and could increase seed production profits. This study was conducted to...

Germination and dormancy of meadowfoam seed

Creator:: Mmolawa, Onesimus B.
Abstract:: Meadowfoam (Limnanthes spp.) is a potential oil seed crop being developed for commercial production in the Willamette Valley. The seeds are characterized by poor germination at warm temperatures. It would be desirable to overcome this temperature-related dormancy problem so that better stand establishment could be realized from early fall planting....

Effect of seed deterioration on germination of wheat under environmental stresses

Creator:: Than, Mya
Abstract:: Germinating seeds often encounter stress conditions of temperature, moisture and oxygen in the field. Germination tests conducted under these stress conditions in the laboratory might be methods of differentiating high and low vigor seeds. The objectives of this study were to (1) determine if these stress conditions reduce germination performance...

Factors affecting stand establishment and yield of meadowfoam (Limnanthes alba Benth.)

Creator:: Nyunt, San
Abstract:: Germination of meadowfoam (Limnanthes alba Benth.) seed is inhibited by warm soil temperatures. This has led to recommendations for planting from early to mid-October when soil temperatures are below about 15°C. Objective data on the effects of planting date on stand establishment and yield are not available. These studies were...
