Several studies have described the effect of DLI on the growth and development of bedding plants. Plant growth measured in terms of dry mass accumulation, leaf area, and plant height are affected by DLI. For example, White and Warrington (1984) observed an increase in geranium plant dry mass from 2.9 to 3.4 g as the DLI increased from 6.5 to 19.4 , while the leaf area per plant decreased from 1047 to 820 cm2 as DLI increased from 8.7 to 20.5 mo1m2d. Niu Ct al. (2000) reported that the dry mass of pansy ‘Delta Yellow Blotch’ increased by 40% as the DLI increased form 4.1 to 10.6 . Kaczperskiet al.(1991)reported that petunias grown at 6.5 were up to 6 cm taller than plants grown under 13.0 .DLI also affects flowering in terms of the rate of flower development and flower size. For example, increasing the DLI delivered to geraniums form 3.2 to 24.3 resulted in a 29-d decrease in time to visible bud to flower (Armitade et al.,1981).Time to flower for petunia decreased by 3 weeks as DLI increased form 6.5 to 13.0 (Kaczperski et al., 1991).Pansy flower size increased by 25% and time to flower decreased by 4 to 12 d, depending on cultivar, when DLI increased form 4.1 to 10.6 (Niu et al. 2000).
Managing the irradiance delivered to the greenhouse crop is critical for successful bedding plant production and greenhouse business profitability. Irradiance can be manipulated with supplemental lighting, shade curtains, retractable roofs and hanging basket production. A greater understanding of bedding plant responses to DLI will improve grower’s ability to more effectively utilize greenhouse space and manipulate the irradiance delivered to bedding plant crops. Therefore, the objective of this study was to quantify the effect of DLI on the growtf and flowering of eight bedding plant species.
