POST HARVEST CONSERVATION OF GLADIOLUS FLOWERS (GLADIOLUS COMMUNIS)
In order to minimize these losses, studies were conducted to determine the effects of some chemicals wich promote a later senescense, through the following treatments: control sample destillated water, potassium nitrate 40 ppm, gibberellic acid 60 ppm, magnesium sulfate 40 ppm. After harvesting, the flower branches were immersed in the solutions, where they stayed till the senescense began.
Flowers were daily evaluated, through the grade criterion, considering the wilting of the first flowers as a sign of senescense.
In this test conditions, distilate water was more efficient in maintaining flowers quality and longevity, than the other tested products.
