Abstract
Abstract Geranium cultivars ‘Sooner Red’ (seed) and ‘Yours Truly’ (cuttings) were grown in the greenhouse and treated with 0 ppm or a double foliar application of 1500 ppm chlormequat (Cycocel). Growth and flowering were evaluated and then plants were planted outdoors and grown under full sun, 30% and 63% shade to determine residual effects of the chlormequat applications. During greenhouse production, chlormequat treated plants were significantly shorter than untreated plants for both cultivars. Flower production by 15 May was not affected significantly. There was no interaction between chlormequat treatment and shade level. Chlormequat increased flowering significantly for ‘Sooner Red’ 1-15 June. This trend was reversed later in the season. Flowering of ‘Yours Truly’ was unaffected by chlormequat application. Chlormequat-treated ‘Sooner Red’ plants remained significantly shorter than untreated plants throughout the season. As the shade level increased, flower production declined on ‘Sooner Red’. ‘Yours Truly’ performed equally well in sun or 30% shade, but plants in 63% shade produced fewer flowers. The 63% shade increased plant height for both cultivars. As shade increased, final dry weight decreased for ‘Sooner Red’ but not for ‘Yours Truly’.
