Investigations were carried out under the All India Co-ordinated Floriculture Improvement Programme, College of Horticulture, Vellanikkara during 2012-2013 to study the effect of pre cooling temperatures on the keeping quality of cut anthurium stems. The cut flowers of Anthurium andreanum 'White King' were harvested early in the morning and subjected to pre cooling at three different temperatures for three durations. The longest vase life of 19.33 days was obtained in the pre cooling treatments, T6 (12°C for 5 h) and T8 (14°C for 3 h). This was followed by T5 (12°C for 3 h) which showed a vase life of 15.67 days. Experiments were also carried out to study the effect of holding solutions on the keeping quality of anthurium cut flowers. The freshly harvested flower stems were put in different vase solutions and evaluated at 23±2°C after recutting the basal portion under water and keeping in holding solutions at 16 h illumination (1000 lux intensity provided by 40 W fluorescent tubes) under laboratory conditions. Of the eleven treatments tried, the flowers subjected to the treatment sucrose (5%) + Al2(SO4)3.16H2O, 300 ppm) (T7) exhibited the highest vase life (14 days). This was followed by T1 (NaOCl 50 ppm) (13 days) which was on par with T2 (Al2(SO4)3.16H2O, 300 ppm) and T4 (Al2(SO4)3.16H2O, 300 ppm + kinetin, 25 ppm). Total water absorbed ranged from 4.33 mL (T1) to 16.67 mL (T8). Phytotoxic symptoms were not observed on the spathe in any of the treatments.
