ABSTRACT
|
Gerbera is an important cut flower that is famous for its attractive and wonderful colors. The gerbera is produced in all around the globe especially in South East Asian country of Japan and in Netherlands in Europe. The short vase life of gerbera is limiting factor in earning full profit from gerbera cut-flower sale. The standardization of suitable substrate for extending vase life of gerbera is not present. The gerbera was placed in substrates 6-Benzyleadenine, Silicic acid and Silver nitrate (20, 40, 60, 80 and 100 ppm) with sucrose (5, 10, 15, 20 and 25g), respectively. The cut flower response was observed by observing the time (days) for sustaining the freshness of cut flowers. Net fresh weight (g) after 15 days according to the formula and Dry weight of the flower (Flower head + flower stem) were taken on placing flowers at 50oC in incubator for 36 hr. The environment of laboratory during research was 20oC. The best response for extending the freshness was observed in cv. Bonnie (Orange) that performed excellent when placed in medium level of 6-Benzyleadenin (20-40ppm with 10-15g/l of Sucrose). The results of 6-Benzyleadenin (20-40ppm with 10-15g/l of Sucrose) are recommended to common retailers for extended storage life of gerbera cut-flower prior to sale. The present substrate is easy to use and non-toxic for extending the vase life/freshness of gerbera cut flower.
