Abstract:
An experiment was conducted to study the effect of different concentrations of floral preservatives on vase life of gypsophila flowers at Floricultura, l Research Station, SKLTSHU, Rajendranagar, Hyderabad during 2019 - 2020 and 2020 - 2021. The results of the experiment revealed that, among the different floral preservatives studied, the treatment cobalt chloride at 100 ppm was very effective in increasing the vase life of gypsophila flowers (13.33 days). It has led to increased water uptake (15.23 g/f), transpirational loss of water (16.72g/f), maximum fresh weight change (106.92%), water balance (4.840 g/f), minimum physiological loss in weight (4.71%), minimum optical density (1.735) and low microbial count (6.040 x 10-5 cfu/ml.) and control (distilled water) recorded minimum vase life (5.10 days), water uptake (7.44 g/f), transpirational loss of water (10.39 g/f) fresh weight change (85.15%), water balance (2.640 g/f) maximum physiological loss in weight (8.78%), maximum optical density value (1.858) and high microbial count (7.580x 10-5 cfu/ml).
