Temperature, an environmental factor affecting cut flowers' physiological state, is expected to affect scent emission. We investigated emission from carnation flowers of two types (Dianthus caryophyllus L.), exhibiting fruity (because methyl benzoate) and spicy eugenol) scents, at various temperatures (10°C, 15°C, 23°C, 28°C). Cut harvested on the day flower opening were used for analysis. Scen...

Photo 1: The inset shows a Dianthus pavonius flower infected with the Microbotryum. anthers of plant are covered in dark brown teliospores. background setup floral arrays that were used to test pollinator observations. Three triangular blocks set up 15 tubes two cut virgin flowers per tube. Within block, all one type: diseased, healthy hermaphrodite, or female. We observed number visits each bl...

2,4-Pyridinedicarboxylic acid (PDCA) is a structural analog of 2-oxoglutarate and has been shown to inhibit 2-oxoglutarate-dependent dioxygenases by competing with 2-oxoglutarate, and ethylene production in detached carnation flowers by competing with ascorbate on 1-aminocyclopropane-1-carboxylate (ACC) oxidase action. In the present study, the inhibition of ACC oxidase action by PDCA was confi...
