The aim of this research was to evaluate the quality and vase life of flower stalks of chrysanthemum cultivated in a traditional system and in three concentrations of the Steiner nutrient solution (12.5; 25.0 and 37.5%). We determined five points of stalk cut in function of the flower opening: 1) 5 to 8 cm; 2) 8.1 to 9 cm; 3) 9.1 to 10 cm; 4) 10.1 to 11 cm; and 5) 11.1 to 12 cm; in which vase life, changes in stalk weight during vase life and sugar concentration at harvest in leaves were evaluated. A negative correlation between vase life and loss of weight in stems was observed. The diameter between 11.1 and 12 cm was not reached with the traditional system of cultivation; furthermore, these plants had a lower duration in vase life in the rest of points of stalk cut. In general, the higher concentration of sugars in leaves was recorded in plants treated with a nutrient solution of Steiner at 37.5%.
