A viewpoint on Indian ricegrass research: its present status and future prospects.

摘要: Indian ricegrass (Oryzopsis hymenoides (Roem. & Schult.) Ricker) is adapted to sandy arid areas of much the western USA and a highly desirable species on winter range sites. Seed typically dormant. Mechanical dormancy has been reduced by mechanical sulfuric acid scarification, physiological with stratification, giberellic acid, kinetin. A better understanding relationship between may lead practical procedure for breaking in harvested seed. Alternatively, environmental factors seed production already low Establishment success will also depend development appropriate seedbed management practices various soils. Reduction currently large shattering losses would have favorable impact economics production. An interdisciplinary approach including physiology, ecology, technology, plant breeding can potentially solve these problems. The potential seeding improving rangelands only be realized after becomes available, are developed, reduced.
