The study of opening of inflorescences and the vase life (Dendranthema grandiflora Tzvelev. ‘Bronze Repin’) early picked of chysanthemum, was carried out in an experiment entirely set up in bifactorial 2 x 6 with five repetitions, at the Department of Fitotecnia of Santa Maria’s Federal University. The stems were stored at 2ºC or 5ºC for 7 days, prior to being treated with pulsing solutions for 24 hours and maintained in vases with distilled water, renewed every two days. The solutions used as follows: Water (control); Silver Thiosulfate-STS 11mg.L-1 (Crysal AVB); Giberelic Acid-GA3 50mg.L-1 (Pro-gibb); Sodium Hipochloride-NaOCl 200mg.L-1; 8-Hidroxyquinoline-8-HQ 100mg.L-1; Tiabendazole-TIBA 100mg.L-1 (Tecto 100). With the exception of the control, all solutions contained 2% sucrose. Perfect opening of the flower was not achieved, but vase life could be extended in order to place them in the market.
