Evaluation of postharvest storage and treatments in cut ruscus foliage / R. Bulgari, M. Negri, A. Ferrante. - In: ADVANCES IN HORTICULTURAL SCIENCE. - ISSN 1592-1573. - 29:2-3(2015), pp. 103-108.
Abstract:
Danae racemosa (L.) Moench is an important cut foliage in the ornamental market. During postharvest, leaf
senescence symptoms are leaf yellowing, weight loss and/or abscission of leaves. The aim of this work was to evaluate
the effect of pre-treatments for 24 h with glycerol and Thidiazuron (TDZ) on Danae vase life before and after storage.
Treatments were applied in vase water containing glycerol 0.1, 1 or 10 mM, 10 μM TDZ and a combined treatment of 10
μM TDZ plus 10 mM glycerol. The effect of treatments was evaluated through the determination of vase life, chlorophyll
content, chlorophyll a fluorescence parameters, sucrose and total sugars content. The cut foliage were stored in sealed
plastic bags and placed in a dark room at 4°C for two months. The vase life, before and after storage, was determined in
a controlled chamber set to 20°C and RH 50-60% with a light intensity of 20 μmol m-2 s-1. Results demonstrated that 10
μM TDZ plus 10 mM glycerol was the most effective treatment in maintaining quality during vase life of stored and not
stored cut foliage.
