Abstract/Contents: | "One hundred cores (10 x 10 x 12 cm) of Kentucky bluegrass (Poa pratensis L. `Nugget') were removed from an etablished seed field, potted, and subjected to two clipping treatments after seed harvest (clipping at 2.5 cm to simulate straw and mechanical stubble removal and clipping at 7.5 cm to simulate straw removal) and two fertilizer treatments (solutions with and without the equivalent of 100 kg ha-1 of N). The plants were then subjected to a cold treatment (98 d at 2.5 C) to induce flowering. Added N increased the number of large tillers formed before the cold treatment, and produced similar increases in the number of initiated tillers and flowering shoots. Added N resulted in larger inflorescences with more spikelets. Close clipping (2.5 cm) did not affect tillering or flowering shoot density, but reduced stem length and resulted in smaller inflorescences with fewer spikelets." |
