Kinetin and Cycocel effects on vase life, flower stem anatomical structure and floral stem bending of Carnation plant Dianthus caryophyllus L.

Abstract

Abstract This study was conducted at the department of horticulture –college of agriculture - Basrah university, to investigate the effect of kinetin at 0, 50 and 100 mg/l and/or cycocel at 0,1000 and 2000 mg/l on anatomical structure of flower stem of Carnation plant Dianthus caryophyllus L. in a factorial experiment designed with RCBD in the lath house. Plants of eight months old were spread with kinetin and/or treated with cycocel as a soil drainage and results showed that spraying with kinetin at 50 or 100 mg/l led to an increase in the number of cell rows and thickness in xylem and Phloem tissues, and reduced the flower stem bending in vase at both growing seasons. Adding 1000 or 2000mg ccc/l led to an increase in the previous indicators.
