Longevidade de inflorescências de lírio, de diferentes estádios de colheita, pré-tratadas com sacarose e tiossulfato de prata (STS)

摘要: Flower senescence is triggered by physiological changes including degradation of starch and chlorophyll, increase in respiration ethylene production. Pulsing cut flowers with STS one efficient way to inhibit action To evaluate the effects combined or not sucrose on flower longevity quality, lily inflorescences cv. Ace were pulsed 5% for 12 hours, 1mM 15 minutes, + control (distilled water) harvested three bud at different ages. They evaluated length opening buds, relative water content, content chlorophyll longevity. The lilly variety influenced stage harvest, longer younger stage, A. Inflorescences A had bigger diameter, but treatment reduced quality. improved buds increased vase life. Thus use allowed harvesting earlier increasing
