Abstract:

The aim of this work was to propose a methodology for commercial classification of gerbera´s capitulum based on the trans flowers overlap coefficient. Three to eight capitula of twenty-eight cultivars of gerbera cut flower and seven non-commercial accesses were used. The width measurement of the trans flowers group (internal ray flower) as well as the sum of the width of the trans and ray flowers (external ray flower) groups were taken from each capitulum. The average of each access and the overlap coefficient were calculated (CS = width of the trans flowers group / Σ of the width of the trans

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 gro

Better understanding of the effects of irrigation frequency and dose on flower production of gerbera plants (Gerbera jamesonii) can lead to optimal water management and crop yield. Measurements of greenhouse microclimate and production and quality characteristics of a gerbera crop were carried out under two irrigation frequency regimens in soilless cultivation in a greenhouse located in Arta, Greece. Irrigation scheduling was based on solar radiation and performed whenever accumulated solar radiation energy outside the greenhouse reached 1650 kJ·m−2 [high irrigation frequency (HIF)] or 3300 kJ

Photoperiodic flowering response varied with the 3 cultivars; ‘Appelbloesem’ was not sensitive to photoperiod; ‘Oranje Nasau’ and ‘Fabiola’ were promoted by short day (SD). In pot-grown Gerbera, SD increased the number of flowers (inflorescences) per plant of ‘Oranje Nassau’ and ‘Fabiola’ in the summer-fall and fall-winter.

The influence of different light intensities (L0: full sunlight; L1: reduced sunlight; L2: 60% reduced sunlight) showed significant variations on growth and flower characteristics. Forty per cent reduced sunlight was more effective on growth and flower production than 60% reduced or in full sunlight. Tallest and thickest peduncles were produced (28.5 and 1.7 cm, respectively) with L1, similarly bigger flowers (6.0 cm diameter) were also found with L1 in comparison to L0 and L2.

Abstract:

One of the critical quality criteria in cut flower marketing is vase life. The neck bending issue observed in gerbera flowers can substantially reduce vase life. This study aimed to identify effective vase solutions to prolong the vase life in the ‘Yeliz’ and ‘Rosalin’ gerbera varieties. Seven different vase solutions were evaluated: sodium dichloroisocyanurate (DICA), sodium hypochlorite (klorak), sodium hypochlorite + sucrose, 8-hydroxyquinoline citrate (8-HQC), perlan + sodium hypochlorite, and perplex + sodium hypochlorite and potable water (Ks: control). Parameters such as vase life, tota

Abstract:

The effect of pretreatment with gibberellin A3 (GA3) and calcium chloride (CaCl2) on the vase life of cut gerbera ‘Minou’ was investigated. Cut gerbera flowers were treated with GA3 and/or CaCl2 for 24 h and then transferred to an antimicrobial solution. Pretreatment with GA3 at 0, 29, 72, 144, and 289 µM delayed the opening of the tubular florets and promoted stem bending due to elongation of the flower stems, which shortened vase life. When cut gerbera was pretreated with 144 µM GA3 in combination with CaCl2 at 90, 180, 270, and 360 mM, stem elongation was suppressed with the increasing conc

Scape bending is the primary cause shortening the vase life of cut gerbera flowers (Gerbera jamesonii ‘Harmony’). A previous study showed that this bending is closely related to the scape hardness, which is attributed to cell wall rigidity maintained by calcium ion bonds. In this experiment, the developing gerbera scape was sprayed with 0.5 and 1% calcium chloride to determine whether exogenous calcium directly influences scape hardness and whether it is related to pectin crosslinks. The calcium spray hardened the scape by 12% and efficiently reduced bending, thereby prolonging the vase life o

Cut flowers are one of the most important floricultural products and one of the features that define its quality is vase life. Thus, longer vase life will be achieved when production sites are closer to the consumer market. Based on the above, this experiment compared vase life of rose, gerbera and chrysanthemums supplied by Pelotas’s local growers and by São Paulo’s wholesalers. For each treatment (origin), 20 stems of each species were evaluated.
