Abstract

Eight bedding plant species were grown from plugs obtained from two sources. The plugs were transplanted into jumbo six packs and sprayed with a solution of chlormequat/daminozide with concentrations of 1000/800, 1250/1250, or 1500/5000 mg.L-1 when new growth was ≅5 cm in height or width. Three different species were grown in the fall (Dianthus chinensis L., 'Telstar Mix', Petunia xhybrida Hort. Vilm.-Andr., 'Dreams Red', and Viola xwittrockiana Gains., 'Bingo Blue'), winter [Antirrhinum majus L., 'Tahiti Mix', Matthiola incana (L.) R. Br., 'Midget Red', and P. x hybrida, 'Dreams Mix'], and spring [Catharanthus roseus (L.) G. Don, 'Cooler Pink', Salvia splendens F. Sellow ex Roem. & Schult., 'Empire Red', and Begonia xsemperflorenscultorum Hort., 'Cocktail Mix']. The treatments significantly reduced finished plant size of all species for each season. There was a significant difference in finish size between sources for Dianthus, Antirrhinum, Matthiola, Catharanthus, Salvia, and Begonia. The efficacy of chlormequat/daminozide also differed for each source of Dianthus, Matthiola, and Begonia, but the treatments minimized the differences in finish size between sources for Petunia and Viola. Chemical names used: (2-chlorethyl) trimethylammonium chloride (chlormequat); (N-dimethylaminosuccinamic acid) (daminozide).
