Post-harvest characteristics of cut carnations as the result of chemical treatments

Abstract: Cut flowers of Dianthus caryophyllus L. cv. Asso were treated with 8-hydroxyquinoline sulphate (8-HQS) at 200 and 400 ppm with or without sucrose at 50 g l-1, silver thiosulphate (STS) at 0.2 and 0.4 mM with or without sucrose at 50 g l-1,and 1-methylcyclopropene (1-MCP) at 0.3, 0.5 and 0.7 g m-3 for 6 h to study the effect of these chemicals on post-harvest quality. 8-HQS treatments increased the vase life and the percentage loss of initial fresh weight compared to the control. In addition, the vase life was … Show more

“…Similar results were obtained by H a s s a n and S c h m i d t [28] in their research on Dianthus caryophyllus L. J a n o w s k a , while J e r z y [19] obtained interesting results when observing the response of Zantedeschia elliottiana leaves to storage in 8-hydroxyquinoline sulphate. In the case of the 'Black Magic' cultivar, no influence of storing in 8HQS was reported.…”

“…HQS was used in all solutions to prevent the growth of microorganisms in the vase water and xylem vessels during long observation periods (>20 days); it is known to be efficient and safe for many cut flowers including carnations (Hassan and Schmidt, 2004).…”

“…Anju et al (1999) observaram que hastes de crisântemos tratadas com 8-HQS + sacarose tiveram a vida de vaso prolongada e menor perda de massa fresca. Nos resultados obtidos para Chrysanthemum morifolium por Hassan & Schmidt (2005), verifica-se que a perda de massa fresca foi diminuída de acordo com o aumento na concentração de 8-HQS. A adição da sacarose não minimizou as perdas, levando ainda a um efeito negativo.…”

“…Dentre as soluções testadas, Figura 2 -Quantidade de botões, flores entreabertas e abertas durante os 12 dias que as hastes de crisântemos foram submetidas a cinco soluções de manutenção e armazenadas por 12 dias a 22º C. (2000), que armazenou flores em baixas temperaturas, o acréscimo de flores abertas do início ao final do armazenamento foi de aproximadamente 10%. Nos resultados obtidos por Hassan & Schmidt (2005) mostra-se que a utilização do 8-HQS em tratamentos para hastes de crisântemos, prolongou a vida de vaso e a qualidade das flores, independente de estar associado ou não à sacarose. À medida que a concentração de sacarose nas soluções aumentava, a resposta das flores para a abertura floral foi maior.…”
