Correlation and Regression Studies on the Effect of Biocides on Vase Life of Carnation (Dianthus caryophyllus l.) Cv. Dona

Abstract

The present study explores correlation and regression analysis on the effect of biocides on vase life of carnation (Dianthus caryophyllus l.) cv. Dona. Keeping quality is a critical factor in determining the quality of cut flowers for both domestic and international markets. To extend the vase life of cut flowers, it is advised that chemical preservatives be added to the holding solution. Due to its beauty, colour diversity, exceptional keeping quality, and vast range of flower forms, the carnation (Dianthus caryophyllus L.), a member of the Caryophyllaceae family, is one of the most significant cut flowers in the world. However, one of the most important concerns in the floriculture sector is preserving the quality and longevity of cut flowers. Cut flowers, particularly carnations, face challenges in maintaining quality and longevity due to issues like microbial blockage and physiological disruptions in the stem. The chemical composition of the vase solution plays a crucial role in preserving cut flowers. Since a variety of biocides have been proposed as a means of preventing the growth of microorganisms in vase solutions, 10 treatments were tested in this experiment, and the results showed that vase life had significantly negative correlations with ODVS and stem curvature and significantly positive correlations with Water uptake (WU), Transpirational loss of water (TLW), Water balance (WB), and the number of days it takes to flower. This shows that WU, TLW, WB, and FWC increased vase life, but that the major influence lowered vase life by reducing WU, TLW, and WB in the vase solution, as indicated by the negative correlation of ODVS.
