Abstract
The present investigations was carried out at the Department of Postharvest Technology, College of Horticulture, Mudigere during 2015-16, to develop vase-tablet formulation and to evaluate their effect on vase life attributes in anthurium and gerbera cut flowers. In experiment-Ia and Ib, best two vase-chemical combinations for anthurium and gerbera cut flowers. Anthurium var. Tropical was placed in Sucrose (2.0%) + Sodium hypochlorite (0.3%) + Benzyl adenine (10.0 ppm) and Sucrose (2.0%) + Sodium hypochorite (0.3%) + Aluminum sulphate (50.0 ppm). Whereas, when gerbera var. Julia was placed in Sucrose (1.5%) + Sodium hypochlorite (0.3%) + Benzyl adenine (20.0 ppm) and Sucrose (1.0%) + Sodium hypochlorite (0.3%) + Benzyl adenine (20.0 ppm) significantly influence quality of flowers.
Further, the two best standardized chemical combinations used for development of tablet formulation with five different carrier materials and their effect was studied in experiment-IIa and IIb. It was found that anthurium were placed in Sucrose (2.0%) + Sodium hypochlorite (0.3%) + Benzyladenine (10.0 ppm) with pregelatinized starch carrier material exhibited the highest cumulative water uptake (50.16g), cumulative transpiration loss (48.93g), cumulative water balance (0.75g), relative fresh weight (60.21%), membrane stability index (60.02%), vase life (23.71 days) and the lowest ion leakage (39.98%) and tablet cost (` 0.66/day/flower) was on par with Sucrose (2.0%) + Sodium hypochlorite (0.3%) + Benzyladenine (10.0 ppm). Wereas, when gerbera placed in Sucrose (1.5%) + Sodium hypochlorite (0.3%) + Benzyladenine (20.0 ppm) with pregelatinized starch carrier material showed the maximum cumulative water uptake (63.41g), cumulative transpiration loss (67.71g), cumulative water balance (-3.70g), relative fresh weight (72.52%), membrane stability index (60.18%), vase-life (13.94 days) and the minimum ion leakage (39.82%) and tablet cost (` 0.92/day/flower) which was on par with Sucrose (1.50%) + Sodium hypochlorite (0.3%) + Benzyl adenine (20 ppm). Hence pregelatinized starch based tablet is compatible for maintaining longevity and quality of anthurium and gerbera cut flowers.
