2,3-Dihydro-5-6-diphenyl-l,4-oxanthin (UNI-P293), was used to determine its effectiveness as a disbudding agent of Chrysanthemum morifolium cv. May Shoesmith. Concentrations of 0.5, 0.75 and 1.0% were applied on the 18th, 21st and 24th short day (SD). The optimum concentration on the 18th SD was 0.5% and 1.00% on the 21st SD. There was no difference among concentration levels on the 24th SD. Flower size and date of anthesis were not adversely affected when manual disbudding was used as a supplement to chemical treatment, but smaller flowers and delayed anthesis usually occurred when only the chemical was used for disbudding. All treated plants were shorter than untreated plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
