Abstract/Contents:"Field trials were conducted in 1985 and 1986 to assess the effects of the growth regulator RSW0411 on a Lolium perenne L. (perennial ryegrass) seed crop. Applications were made at spikelet and floret initiation, and at 1, 2, 3 and 4 kg active ingredient ha -1. Seed yield increases in 1985 were associated with increased reproductive tiller numbers and seed numbers, but in 1986 there were no seed yield responses. Lodging was less severe in 1986, and there was less secondary tillering during seed maturation. In l985, fertile tiller numbers were lower in control plots at harvest. These results are discussed in relation to the seasonal disparity in seed yield response. RSW0411 application significantly decreased culm lengths by shortening the basal internodes, and this effect was greater with higher application rates. Stem width was increased in 1985 at the base and middle of the stem, and earlier applications increased the basal width by more than later applications. Germination was not affected by RSW0411 treatment, except when applied at 4 kg active ingredient ha -1 in 1985, when there was a small decrease. This was related to a low 1000-seed weight, and is discussed in relation to seed maturity at harvest."
