“…longevity in gerberas. Amariutei et al (1986) reported consistent differences in vase life between two gerberas. 'Symphonie' lasted 2 days longer than 'Richard' either when treated with pulsing agents or when untreated.…”

A broad source of Gerbera × hybrida Hort. germplasm was evaluated for vase life. Senescence mode, i.e., bending or folding of stems or wilting of ligulae was also recorded for flowers evaluated. Intensive selection was practiced to improve vase life. About 10% of the plants from a sample population were selected for having flowers with high vase life. Progeny means for vase life resulting from a topcross between these plants and `Appleblossom' were used to select five plants (about 1.5% of the sample population) whose flowers had high vase life. A diallel cross using these five plants as parents resulted in a progeny population with an increase in mean vase life of 3.4 days compared to mean vase life for the initial sample population. Increases in vase life means for days to bending, folding, and wilting were 0.3, 3.5, and 1.2 days, respectively. Plants with flowers which senesced due to wilting had the longest mean vase life before and after breeding. Changes in proportion of senescence modes were observed; bending decreased, folding and wilting increased. Frequencies of bending, folding, and wilting were compared to vase life means for 10 progenies. Proportion of bending generally decreased as vase life increased.

“…Postharvest longevity of gerbera has been extended using postharvest treatments (Abdel-Kader and Rogers, 1986;Accati, 1989;Amariutei et al, 1986;Kohl, 1968;Marousky and Woltz, 1975;Meeteren, 1978a;Nowak, 1981;Nowak and Plich, 1981;Waters, 1964) but the extent to which these treatments can improve vase life may be limited by the plant genome.…”

“…Different chemicals have been used in vase solution to extend vase life of cut flowers mainly by improving their water uptake and reducing transpiration, thereby promote the vase life (Lu et al, 2010). Vase life of gerbera can be extended using post-harvest treatments as evidenced by different authors (Abdel-Kader and Rogers, 1986; Accati and Jona, 1989;Amariutei et al, 1986 andNowak, 1981). Aim of this study was to search for the preservative solution(s) for extending vase life of cut gerbera.…”

Silvar Thiosulphate (50-ppm) were used as vase solution to increase post-harvest life of gerbera. Minimum score for petal discoloration (1.6) and flower freshness (3.8) was found from T9. Stem bending (13.7 days), petal discoloration (10.5 days) and petal shriveling (13.3 days) were also found to be delay in T9 treatment. Maximum stem diameter (7.2 mm), solution uptake (72.7 ml), petal water content (72.7%) and vase life (13.3 days) was found from T9 followed by T6. Sugar + Silvar Thiosulphate and Sugar + Citric Acid can lead to extend longevity of cut gerbera by reducing the fungal infection also by increasing solution uptake and supplementing carbohydrate.

“…La finalidad de las soluciones preservativas es incrementar la vida útil de las flores; la mayoría de éstas contienen sustratos, bactericidas y antimicóticos (Wounter et al, 1994). En los pétalos el contenido de azúcar disminuye durante la vida florero, causando marchitamiento (Amariutei et al, 1986). En clavel el azúcar en la solución preservativa disminuye los efectos de la senescencia (Acock y Nichols, 1979).…”

Gerbera jamesonii presenta una vida florero corta caracterizada por el doblado del tallo floral (escapo). Con el objetivo de alargar la vida f lorero de gerbera se probaron tres concentraciones de CaCl2 (0.1, 0.5 y 1.0%) en las variedades Duela y Shirlaine. Las concentraciones 0.5% y 1.0% redujeron la pérdida de peso de la f lor entera y lígulas en comparación con el testigo. La concentración 0.5% fue el mejor tratamiento, aumentó la vida media florero (25 d Duela y 24 d Shirlaine). Los tallos f lorales tratados con CaCl2 acumularon más Ca+2 en el ápice (25.33 μg g-1 Duela y 64.0 μg g-1 Shirlaine), permaneciendo erectos por más tiempo que el testigo (9.67 μg g-1 Duela y 13.67 μg g-1 Shirlaine). Con la concentración 0.5% se hizo un segundo experimento para evaluar los cambios en concentración de carotenos, antocianinas (pelargonidina, cianidina) y fenoles totales de las lígulas. Las antocianinas de Shirlaine, no cambiaron entre tratamientos. Los fenoles aumentaron 21% en Shirlaine y 40% en Duela con respecto a su concentración inicial, en contraste los carotenos disminuyeron al fin de la vida f lorero 60% y 35%. En Duela el tejido interfascicular es más lignificado que en Shirlaine confiriéndole mayor resistencia. El área relativa (%) lignificada de la región media del escapo fue mayor en Duela (7%) que en Shirlaine (4%). La mayor resistencia del tallo de Duela es explicada por su anatomía y lignificación pero el CaCl2 fue efectivo para retrasar la senescencia y el doblado del escapo en las dos variedades.
