USE OF NUTRIENT SOLUTIONS AND TRADITIONAL PRODUCTION SYSTEM OF CHRYSANTHEMUM ON POSTHARVEST QUALITY
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%.
