Impact of certain chemicals on vase-life of different cultivars of China aster and gladioli

Abstract

Two set of experiments were carried out to investigate the effect of vase solution made of different chemicals on vase-life and quality of cut flowers of gladiolus and China aster cultivars. Out of the four vase solutions applied, the treatment with 200 ppm citric acid, 200 ppm AgNO3, 5% sucrose and 0.02% Tween-20 was observed to be the best followed by 200 ppm citric acid, 200ppm CoNO3, 5% sucrose and 0.02% Tween-20, resulting in the longest vase-life and maximum weight gain at third day and total solution uptake. Correlation revealed that floret diameter had a strong positive correlation with loss in weight of vase solution up to ninth day, total weight loss of vase solution, floret opening per cent and vase-life in various cultivars of both crops.
