Seed Development in Orchardgrass (Dactylis glomerata L.) in Relation to Plant Growth Regulators and Spring Nitrogen

Creator:: Morad, Mohammed M.
Abstract:: Orchardgrass (Dactylis glomerata L.) is an important seed crop, but unlike other cool-season perennial grass seed crops such as perennial ryegrass (Lolium perenne L.) and tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.], seed yields have not increased over time so there is considerable room for improvement. Research suggests that plant growth...

Plant growth regulators and shattering control in cool-season perennial grasses

Creator:: Lee, Suk-Kyun
Abstract:: Shattering is a natural phenomenon of floret and spikelet disarticulation across abscission layers of the pedicel and rachilla, respectively, after seed maturation. Seed shattering in cool-season grasses and native grass species is an economic problem in seed production. This study was conducted to determine whether the use of the plant...

Physiological responses of creeping red fescue to stubble management and plant growth regulators

Creator:: Meints, Paul David
Abstract:: Legislation to reduce open field burning in grass seed fields within the Willamette valley of western Oregon changed established production practices. In the creeping grasses such as Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.) non-thermal management resulted in reduced yield. Studies were conducted to examine...

Plant Growth Regulator Combination Effects on Turf-Type and Forage-Type Tall Fescue [Schedonorus arundinaceus (Schreb.) Dumort.] Seed Crops

Creator:: Hudgins, Tara M.
Abstract:: Tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.] is an important forage and turf grass seed crop in Oregon. Use of the stem-shortening plant growth regulator (PGR) trinexapac-ethyl (TE) has gained broad acceptance by tall fescue seed producers in Oregon and elsewhere world-wide as an economical agent of seed yield enhancement through...

Effect of Plant Growth Regulator and Irrigation on Physiological and Harvest Maturity of Red Clover in Relation to Seed Quality

Creator:: Angsumalee, Duangporn
Abstract:: Red clover (Trifolium pratense L.) seed yield can be affected by plant growth regulators (PGR) and irrigation; however, the effects of these factors on physiological maturity (PM), harvest maturity (HM), and seed quality are unknown. The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE, a...

Spring Nitrogen, Plant Growth Regulator, and Defoliation Effects on Seed Production in Two Fine Fescue (Festuca rubra L.) Species

Creator:: Anderson, Nicole P.
Abstract:: One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...

Response of the cyanobacterium Aphanizomenon flos-aquae to vascular plant decomposition products

Creator:: Haggard, Kale G.
Abstract:: Upper Klamath Lake in south central Oregon annually experiences intense blooms of cyanobacteria, primarily Aphanizomenon flos-aquae. Domination of the lake phytoplankton community by this single species regularly results in drastic changes to water quality. Photosynthetic activity of such extensive populations can result in pH over 10. Blooms typically expire in...
