Postharvest Quality of Goldenrod Cut Flowers on Different Vase Solutions Cv. Tara Gold

Goldenrod (Solidago canadensis) is a genus of about 100 to 120 species of flowering plants in the family Asteraceae. Most of them are herbaceous perennial species growing from woody caudices or rhizomes. In floriculture industries, post-harvest losses of flowers are the major problem due to its highly perishable nature and it ultimately affects the quality and vase life of flowers. To overcome these issues proper post-harvest practices are essential. The present research work on the “postharvest quality of goldenrod cut flowers on different vase solutions cv. tara gold” was carried out in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar during 2017 to 2018. The experiment was with five replicates in completely randomized design. Cut flower spikes treated with silver nitrate and 8-HQS at 200 ppm along with sucrose at concentrations of 2, 4, 6, 8% and control (distilled water) were used in the study. The results showed that all treatments had improved the keeping quality and vase life of cut flowers when compared to control. Among all these treatments, silver nitrate 200 ppm + sucrose @ 6% (T3) recorded maximum water uptake, transpirational loss of water, water balance, loss of water and water uptake ratio. Fresh weight, cumulative physiological loss in weight and vase life which was extended to maximum on T3.
