Vase-life of Gerbera jamesonii Bolus cut flowers depending upon; media, mineral nutrition, their morphological attributes and treatment with flower preservative

R. M. Rudnicki, J. Nowak

Abstract


The correlations among different media, mineral nutrition and morphological features of gerbera flowers in relation to their vase-life period investigated. The bast medium for longevity of cut gerbera flowers was the mixture of composted pine bark and peat moss fertilized with N – 250 mg/1 and Mg – 150 mg/1. It was found that cut gerberas lasted longer when they were the Alkemade type, i.e. with wide petals. Yellow flowers remained fresh longer than red and pink ones. It was also found that the vase-life period of gerberas directly correlated with the length of floral stalk, its ability to grow and the inflorescence diameter. The solution of flower preservative Proflovit-72 was effective 'in extending life at room temperature and improved the quality and longevity of flowers which were previously in coldstorage for 1 to 3 weeks.
