Abstract:
The quality of cut rose flowers at the post-harvest stage is affected by the susceptibility to Botrytis flower blight. This parameter may be related to Ca concentration in the flowers. The objective of the present study was to increase the Ca concentration in the stem and petals of roses in order to improve cut-flower post-harvest quality and to reduce the use of fungicides. The effects of the solution composition, Ca, Na, K and Mg concentrations and night irrigation on Ca content in the cut flower and on its quality were studied in greenhouse experiments in Israel and in the Netherlands. The main results and conclusions are: increasing the Ca concentration in the solution from 0.5 up to 5.0 mmol·l-1 increased Ca concentration in the flower organs. Susceptibility to B. cinerea decreased with increasing Ca concentration in the solution and was negatively correlated with Ca concentration in the diagnostic leaf and petal. Potassium and magnesium reduced Ca uptake by the rose flower, and increased its susceptibility to Botrytis flower blight. Night irrigation enhanced the Ca concentration in the leaf but had no significant effect on Ca concentration in the petal and on the susceptibility to Botrytis.

Potassium and magnesium reduced Ca uptake by the rose flower, and increased its susceptibility to Botrytis flower blight.
