While the pink cultivar exceeded the diameter of the inflorescence (66.26 mm), the diameter of the stalk (3.93 mm) and the length of the stalk (22.40 cm). Where the treatment of spraying with a mixture CPPU+GA exceeded the treatment of Roselle extract and control in all characteristics, the number of inflorescences 2.87 inflorescence. plant-1 , inflorescence diameter 65.84 mm, stalk diameter 3.95 mm, stalk length 22.39 cm and vase life 8.99 days.
