“…The importance of tiller position and age in determining which tillers become reproductive was evident in both seasons. In the first season Tiller 2, which was initiated earlier and had more daughter tillers than Tiller 5 (Phillips et al 1996), had a higher proportion of mature reproductive tillers than Tiller 5. This response is believed to have been due to the Tiller 2 daughter tillers having being initiated earlier than those of Tiller 5 and so were better developed suggesting that tiller age, perhaps through its relationship with tiller developmental stage, influences reproductive tiller initiation.…”

The effect of plant density (row spacing / seeding rate), cultivar choice, nitrogen (N) fertilization and close-down date on the number of reproductive tillers surviving to maturity in tall fescue (Festuca arundinacea Schreb.) was examined over a two-year period. A low proportion of reproductive tillers survived to maturity during both seasons. Reproductive tillers surviving to maturity were mostly from the older tiller population groups. The July and August close-down dates had more (1.44±0.36 tillers) surviving reproductive tillers than the September and October close-down dates. More reproductive tillers survived to maturity in Cajun (1.36±0.5 tillers) than in Roa. Row spacing / seeding rate did not appear to influence the number of surviving reproductive tillers per quadrat. Management factors are important in affecting tall fescue seed yields, but the importance of environmental factors must not be ignored.

“…The effect of management and environmental factors on tiller initiation has been described in several publications (e.g. Phillips et al 1996), but only limited information is available on the effects of management on tiller mortality. Tiller mortality is believed to increase as plant density and rates of tiller initiation increase, due to increased competition for light and nutrients (Langer 1963).…”

The effect of plant density (row spacing / seeding rate), cultivar choice, nitrogen (N) fertilization and close-down date on tiller mortality in a dual purpose (forage and seed) tall fescue (Festuca arundinacea Schreb.) sward was examined over a two-year period. Cajun had a consistently lower (P<0.01) tiller mortality than Roa in both seasons. An increase in row spacing or a decrease in seeding rate reduced (P<0.01) tiller mortality. Tiller mortality increased with increased levels of N-fertilization. A relation between tiller age (time of origin) and mortality was identified. The youngest or least developed tillers were found to be less tolerant of stressful conditions than the older or better developed tillers. Tiller mortality was also shown to increase dramatically in spring, irrespective of the type of management applied.
