Four seasons were carried out at the Department of Plant Production, Faculty of Agriculture ”Saba Basha”, Alexandria University in December (2018-2019) on Rosa hybrida L. cv. ”Black magic” cut flowers, June and January (2019-2020) on Helianthus annuus L. cv. ”Sunbright Supreme” (sunflower) cut flowers.
This study aimed to find out the effect of dry cold storage duration and vase life periods as well as pulsing solutions on the postharvest quality of Helianthus annuus L. cv. ”Sunbright Supreme” and Rosa hybrida L. cv. ”Black magic” cut flowers to help the growers to extend the marketing periods and export seasons as long as possible using cold storage facilities without affecting cut flowers standard characteristics.
