Utilization of the night-interruption phenomenon to hasten the seed increase of long-day cereals during short-day regimes in California and Arizona

Creator:: Ebeltoft, David C.
Abstract:: Tests were carried on in growth chambers and in the field to determine if the harvest of daylength-sensitive long-day cereals grown during the winter in Arizona could be hastened 30 days by the use of night interruption. Two durum lines which were near-isogenic for sensitivity to daylength were used throughout...

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...

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 protein content on plant growth of barley and wheat

Creator:: Lopez, Arturo
Abstract:: The purpose of this study was to evaluate the effect of seed protein content on plant growth of barley (Hordeum vulgare L. ) and wheat (Triticum aestivum L. ). The effects of nitrogen application on chemical and morphological characteristics of the seed were also studied. Seeds of 'Casbon' winter barley...

Effect of variety, planting date and plant population on yield and quality of Snap Bean (Phaseolus vulgaris L.) seed

Creator:: Filgueiras, Tarciso de Sousa
Abstract:: The objectives of these experiments were to determine the feasibility of saving seed from snap bean fields in the Willamette Valley that have been bypassed for canning and freezing, and to study the effects of different seed production methods on yield and quality of snap bean (Phaseolus vulgaris L.). Field...

Effect of sheep grazing on subterranean clover (Trifolium subterraneum L.) seed production

Creator:: Steiner, Jeffrey John
Abstract:: Subterranean clover (Trifolium subterraneum L.) seed production practices in Oregon are different from those in Australia. There, seed is produced on fields which are managed primarily for forage. In Oregon, seed fields are managed for seed as the primary product and forage is of secondary concern. Some sheep grazing is...

SDS-PAGE of seed proteins for identification of varieties and species of ryegrass (Lolium spp.)

Creator:: Ferguson, Janet M.
Abstract:: The number of varieties of ryegrass (Lolium spp.) has increased greatly in recent years. An accurate and rapid laboratory technique to identify these varieties would benefit the consumer as well as protect an organization's Plant Variety Protection rights. There is also a need for a technique to complement the seedling...

Identification of species and varieties of ryegrass (Lolium spp.)

Creator:: De Barros, Manoel Bernardo
Abstract:: The objective of this study was to investigate ryegrass seedling characteristics that, by themselves, or combined with presently known characters, could improve varietal identification tests. Thirteen characters were studied on 30 varieties of Lolium multiflorum Lam., L. perenne L., L. rigidum Gaud, and L. hybridum Hausskn., including leaf size and...
