In four experiments the major effect on ̄owering was that of temperature. Temperatures applied between 2 October and 20 February in ̄uenced the time of ̄owering of D. allwoodii, `Doris', while in D. alpinus, `Pike's Pink', temperatures applied over a longer period between 2 October and 11 March in ̄uenced the time of ̄owering. Keeping stock plants at low temperatures, before cuttings were taken, ...

Spatial shifts in insect fauna due to ecological heterogeneity can severely constrain plant reproduction. Nonetheless, data showing effects of insect visit patterns and intensity of mutualistic and/or antagonistic plant-insect interactions on plant reproduction over structured ecological gradients remain scarce. We investigated how changes in flower-visitor abundance, identity and behaviour ove...

Carnation (Dianthus caryophyllus L.) is one of the most important cut flowers in the world. Themajority of thecarnation cultivars are sensitive to ethylene which affected the physiological and biochemical postharvest characteristics of these flowers.Applying inhibitors of biosynthesis and action of ethylene is important factor to protect the display quality and extend postharvest life. In order...
