Confidence limits for fluoresence tests of ryegrass (Lolium sp.)

Creator:

Copeland, L. O. (Lawrence O.), 1936-

Abstract:

Studies were conducted to determine the variability existing in repeated fluorescence tests of annual and perennial ryegrass (Lolium multiflorum and L. perenne, respectively). Sources of variation considered were within-sample error, among-sample error, among-germinator error, and among-laboratory error. These were studied independently and the variation in each was compared to the...

Measurement of outcrossing in Lolium spp. as determined by fluorescence tests

Creator:

Copeland, L. O. (Lawrence O.), 1936-

Abstract:

Research was conducted to determine the distance and amount of outcrossing between varieties of highly fluorescent annual ryegrass (Lolium multiflorum Lam.) and low-fluorescing perennial ryegrass (Lolium perenne L.). Studies were conducted under both spaced-plant and seed production field conditions. Fluorescence tests on seed collected from low-fluorescing perennial ryegrass at successive...
