“…Moreover, bacteria levels of 11 log CFU mL -1 significantly reduce water uptake in 'Charlotte' roses (Macnish et al, 2008). In this study, the high presence of bacteria in the vase solution of all the treatments evaluated seemed not to affect solution uptake (Table 3) since no relation between this parameter and the accumulation of bacteria was observed.…”

“…On the other hand, Macnish et al (2008) recommended 2 µL L -1 of ClO 2 to control bacterial growth during the postharvest life of Gerbera, Gypsophila and Matthiola. However, the same study observed leaf yellowing and premature flower drop at the concentration of 50 µL L -1 applied to others species, such as Alstroemeria and Lilium.…”

“…Chemical preservatives with surfactant effects include 8-hydroxyquinoline citrate, 8-hydroxyquinoline sulfate, alkylethoxylate (van Doorn et al, 2001), Tween-20, Tween-80, Agral-LN (van Doorn et al, 2001), and Triton X-100 (Jones et al, 1993), among others. Those with biocidal effects help to prevent occlusions from occurring mainly at the basal stem end of cut flowers, which strongly decrease water uptake from the vase, and many products have been used in cut flowers for this purpose such as sodium hypochlorite (Macnish et al, 2010), silver nitrate (Figueroa et al, 2005), Physan 20, 8-hydroxyquinoline (Cruz et al, 2006), silver thiosulfate (Figueroa et al, 2005) and chlorine dioxide (Macnish et al, 2008). Despite the benefits described for these flower preservatives, their effects depend on the dosage and duration of exposure (Chao et al, 2010;Macnish et al, 2008), since in certain species, high doses or long exposure may provoke toxicity and thereby reduce vase life by dehydration, browning (van Doorn et al, 2001), leaf chlorosis and premature flower drop (Macnish et al, 2008).…”

ROLE OF FLOWER PRESERVATIVE SOLUTIONS DURING POSTHARVEST OF Hydrangea macrophylla CV. BELA

et al. 2016

Hydrangea macrophylla (hydrangea) is widely used as an ornamental plant and cut flower due to its inflorescence, which is composed of colored bracts. As cut flowers, hydrangeas show a postharvest life of up to 1 month at 2 °C, but little is known about their postharvest life during air shipment. This study was aimed at evaluating the effect of Triton X-100 (surfactant) and ClO 2 (biocide) during an air shipment simulation of hydrangea harvested at two floral stages of development: fresh and antique. Vase life, fresh weight loss (FWL) and solution uptake were evaluated after an air shipment simulation. Furthermore, bacterial counts and microscopic observation of the bracts were performed in order to understand the water relations of hydrangea during vase life. The longest vase life was observed in antique hydrangeas, and the control (deionized water) was the best treatment, reaching up to 32.7 days in this floral stage. FWL was faster when using Triton X-100 (3.83 days to lose 20% of FW) compared to deionized water (8.75 days). However, this flower preservative was efficient at promoting solution uptake (31.96 mL). Bacterial plugging did not appear to occur considering that the high presence of microorganisms counted did not affect solution uptake or vase life. The presence of stomata on the bracts seems to be crucial for the dehydration of the inflorescence, a problem that was not solved by the higher water uptake promoted by Triton X-100. Thus, deionized water was the best treatment, and the effect of flower preservatives in order to extend vase life of hydrangea cut flowers was insignificant.

“…A menor vida de vaso foi observada nas inflorescências mantidas em água desionizada, possivelmente por não ter controlado a oclusão vascular, nem ter fornecido substrato para os processos bioquímicos que ocorrem após a colheita. Em A. majus 'Potomac Pink', a solução contendo 10μL L -1 de dióxido de cloro (ClO 2 ) prolongou a vida de vaso das inflorescências, mostrando que o controle da oclusão vascular tem resultados positivos no aumento da longevidade floral (MACNISH et al, 2008).…”

“…Em seguida, foram distribuídas em vasos contendo 400mL das diferentes soluções avaliadas: (1) água desionizada (20ºC, tratamento controle), (2) água quente (43°C) por uma hora e água desionizada (20ºC) colocada no vaso, (3) solução de Flower ® (Ecoplanet, SC) que foi preparada seguindo as recomendações do fabricante (20ºC), (4) solução de vaso preparada com 200mg L -1 de 8-HQC+20g L -1 sacarose+150mg L -1 ácido cítrico (20ºC), (5) água quente (43°C) por uma hora e Flower ® em solução de vaso (20ºC), e (6) água quente (43°C) por uma hora e solução contendo 200mg L -1 8-HQC, 20g L -1 sacarose e 150mg L -1 ácido cítrico (20ºC) como solução de vaso. Todas as hastes tiveram a base cortada (2cm) a cada 48 horas, no momento em que também foi feita a troca das soluções até o final da vida de vaso das inflorescências, quando apresentaram 50% ou mais das flores e/ou folhas murchas ou caídas (MACNISH et al, 2008).…”

The relatively brief postharvest life of most cut flowers and potted flowering plants can be extended by a range of technologies. Studies have shown that vase life is negatively correlated with respiration after harvest, so prompt cooling to the lowest safe storage temperature is a key to long-distance transport of these perishable crops. Forced air cooling is the method of choice for cut flowers, and vacuum cooling has been shown to be very effective for cooling potted plants. In contrast to some other horticultural crops, controlled and modified atmospheres seem to have little effect on petal respiration, and these techniques have not proved commercially useful in the marketing of many cut flowers. Low temperatures are also important in managing the effect of other factors contributing to early senescence, including water loss, the effects of ethylene, leaf yellowing, and the growth of diseases, particularly caused by Botrytis cinerea. Ornamentals originating in the tropics and subtropics cannot be cooled below 10 C because they rapidly show the symptoms of chilling injury. Chemical strategies to improve the life of ornamentals include the application of abscisic acid to reduce water loss, particularly in potted and bedding plants, pretreatment with the volatile ethylene inhibitor 1-methylcyclopropene (1-MCP) to prevent the 1
