RESUMOO presente trabalho teve como objetivo avaliar o efeito de soluções de condicionamento ("pulsing"), em inflorescências de esporinha (Consolida ajacis) visando ao aumento da vida em vaso pelo uso de sacarose, tiossulfato de prata (STS) e pela combinação destes elementos. As inflorescências foram colhidas, uniformizadas em tamanho e estádio de abertura das flores, e posteriormente colocadas em vasos por 30, 60, 90 e 120 minutos com sacarose a 5%, 10%, 15% e 20 %, ou em solução de STS a 0,2, 0,4, 0,6, 0,8 e 1,0 mM e os respectivos controles com água destilada. Avaliaram-se os efeitos da combinação das soluções de 0,2, 0,4, 0,6, 0,8 e 1,0 mM de STS em combinação com sacarose a 5% por 30 minutos. A utilização de sacarose isoladamente não influenciou a vida em vaso ou a redução da abscisão das flores quando comparado com ao controle. O tratamento com STS, combinado ou não com sacarose a 5%, aumentou a longevidade, a abscisão e murchamento das flores. Condicionamento das inflorescências com 1,0 mM de STS, combinado ou não com sacarose a 5% por 30 minutos, elevaram a longevidade de aproximadamente 8 dias (controle) para o mínimo de 15 dias e reduziu a abscisão das flores de 66,9% para valores inferiores a 17,5% .Palavras-chave: flor de corte,'"pulsing", vida de vaso, abscisão. ABSTRACT Longevity of Consolida ajacis inflorescences influenced by pulsing with sucrose and silver tiosulfateThe present work had the objective to evaluate the influence of silver tiosulfate (STS) in combination or not with sucrose on Consolida ajacis inflorescence vase life. The inflorescences were standardised in length and flower opening and than pulsed for 30, 60, 90 and 120 minutes in 5%, 10%, 15% and 20% sucrose or with 0.2, 0.4, 0.6, 0.8 and 1.0 mM STS, and the control treatments with distilled water. In a second set of experiments the inflorescences were pulsed with 0.2, 0.4, 0.6, 0.8 and 1.0 mM STS combined with 5% sucrose for 30 minutes. Treatment with sucrose did not affect the vase life or flower abscission, when compared with the control. Pulsing the inflorescences with STS, in combination or not with 5% sucrose, were effective in extending the flower vase life and reducing flower abscission and wilting. Pulsing the inflorescences with 1.0 mM of STS mixed or not with 5% sucrose for 30 minutes increased flower longevity from approximately 8 days (control) to about 15 days, and fell down the abscission from 66.9% to values bellow to 17.5%.
