Effect of dry storage on scape bending in cut Gerbera jamesonii flowers.

ABSTRACT :

 

The effect of dry storage on scape bending in cut flowers was investigated in 9 G. jamesonii cultivars (Cora, Donatella, Liesbeth, Mickey, Nikita, Regina, Rosamunde, Simonetta and Terrafame). Freshly cut flowers placed in water for 14 days in summer or winter showed no bending, except for cultivars Cora and Liesbeth. During the summer, dry storage (4 days at 1 deg C) had no effect on most cultivars but increased the curvature in cultivars Cora and Liesbeth, whereas in winter dry storage increased bending in all cultivars tested. Amongst the cultivars tested, no differences were found in water potential after dry storage nor in the water balance during vase life. The scape curvature after dry storage in winter was not correlated with FW of the flower head or the uppermost 12 cm of the scape, nor with scape diameter at 12 cm from the flower head. The percentage DW of the scapes, however, was lowest in Cora and Liesbeth, which may explain why they are apt to bend.
