Abstract
In the view of Benzyladenine (BA), salicylic acid (SA) and nanosilver (NS) potential, the present research was conducted to screen various treatments for promoting the vase life and evaluating the possible physiological induced changes during the postharvest life of gerbera cut flowers (Gerbera jamesonii Dune). The gerbera cut flowers in sixteen different groups were treated in pulse method (24 h) by the four levels of benzyladenine (0, 50, 100 and 150 mgL -1 ) or salicylic acid (0, 50, 100 and 200 mgL -1 ) containing 8% sucrose and then transferred to the solution containing distilled water or nanosilver of 5 mgL -1 . As the time went by, the reduction rates of the weight, the soluble solid contents, anthocyanin levels and the membrane stability were declined by the applied preservatives, BA and SA, which the second one was more effective and the effectiveness of the used preservatives were promoted by the nanosilver usage. The activities of phenylalanine ammonia lyase (PAL), catalase (CAT) and superoxide dismutase (SOD) decreased with the passage of time, however, the applied treatments of SA or BA, especially the combined ones with nanosilver, led to the induced activities of the mentioned enzymes. The applied preservatives had promoting effects on the longevity of gerbera cut flowers where the highest used concentration of SA in combination with nanosilver was the most effective treatment. Results indicated that the efficacy of SA or BA on the vase life of gerbera cut flowers significantly promoted by the applied concentration of nanosilver and with increasing the tested levels of BA, the longevity of treated cut flowers reversely affected, most probably due to
