INFLUENCE OF VARIOUS HOLDING SOLUTIONS ON VASE LIFE OF CHRYSANTHEMUM CV. PUJA

Abstract

The present experiment entitled “Influence of various holding solutions on vase life of Chrysanthemum (Dendranthema grandiflora) cv. Puja” was carried out under Complete Randomized Design with three replications in the Horticulture Laboratory of School of Agricultural Sciences and Technology RIMT University, Mandi Gobindgarh, Punjab during 2020. The result showed that the vase life was significantly affected by different holding solutions. Among the various treatments, T10 (Sucrose 6% + Citric acid 300ppm) was resulted in minimum number of days taken (3.22 days) for bud opening, fresh weight of spike (11.04 g), flower height (6.89 cm), stem diameter (4.85 mm), minimum moisture loss (44.44%), maximum vase life (19.33 days) and dry weight of spike (2.46 g). Whereas, treatment T9 (Sucrose 4% + Citric acid 200 ppm) was resulted in maximum total solution consumption (24.00 ml). Maximum diameter of the flower on 6th, 9th and 15th days of experiment was recorded in treatment T10 (Sucrose 6% + Citric acid 300 ppm). Treatment T9 (Sucrose 4% + Citric acid 200 ppm) was also resulted in maximum diameter of the flower on 3rd and 12th day of trial. Treatment T10 (Sucrose 6% + Citric acid 300 ppm) was resulted in maximum weight of spikes on 3rd, 6th and 9th day of experiment. And also maximum weight of spikes on 12th and 15th days of trial was observed in treatment T9 (Sucrose 4% + Citric acid 200 ppm).
