Influence of pulsing and holding solutions in vase-life of Gladiolus cv. American beauty

Abstract

The results revealed that the vase life were found maximum (11.37days) with the 10% sucrose +8-HQ 200ppm in the factor A. In case of factor B Silver Nitrate @ 50ppm gave the better vase life of (10.80days). In the interaction effect treatment combination 8% sucrose + 8-HQ 200ppm + Citric acid @ 2000ppm gave the maximum vase life of (11.94days).In the factor A the percentage of floret opening was recorded maximum ( 93.10%) in 10% sucrose + 8-HQ 200ppm and in the factor B Citric acid @ 2000ppm gave the maximum (89.28%). In case of interaction 8% sucrose + 8-HQ 200ppm + Citric acid @ 2000ppm gave the maximum of (95.21%).Diameter of floret were found maximum (12.36cm) with the 2% sucrose + 8-HQ 200ppm in factor A and in factor B it was found maximum (11.71cm) with Aluminum sulphate @ 300ppm.in case of interaction treatment combination maximum diameter (13.18cm) were found with 2% sucrose + 8-HQ 200ppm + Aluminum sulphate @ 300ppm. In the water relation factor A 8% sucrose + 8-HQ 200ppm and factor B Silver Nitrate @ 50ppm showed the remarkable influence on water uptake (61.7ml) and water balance (0.981) as individual and in the interaction effect also. The minimum water losses (60.86ml, 60.99ml) were observed with the factor A 8% sucrose + 8-HQ 200ppm and factor B Silver Nitrate @ 50ppm but in case of interaction the minimum loss (60.36ml) were found with the distilled water + Silver Nitrate @ 50ppm.
