Abstract :
Gerbera one of 10 important cut flowers in the world and Iran. One of the
most problems is low-life after harvest and neck bending. Producers want to
increase longevity of these flowers with using chemical solutions. With the
aim of achieving the best chemical treatments to increase flower vase life
gerbera Goodtimming, nano silver (5 mg l-1), humic acid (50 mg l-1),
gibberellic acid (2.5 mg l-1) and Lactobacillus plantarum 110 CFU m l?1 and
Lactococcus lactis 110 CFU ml?1 with sucrose (4%) compared with controls.
This study in carried out with 6 replications. Cut flowers recutted to 35 ± 2
cm, and then tested in different solutions for 20 days. The results showed that
silver nanoparticles (5 mg l-1) + sucrose 4% + gibberellic acid 2.5 mg l-1 with
the 19.5 days vase life compared with controls (17.67days) had the highest
durability. Distilled water + sucrose 4% with 5.98 mm stem diameter was
better than control (5.49 mm) (P?0.01), while humic acid 50 mg l-1 + sucrose
4% + gibberellic acid 2.5 mg l-1 had lowest average daily stem diameter (5.44
mm), respectively. Highest water uptake observed in silver nanoparticles 5
mg l-1 + sucrose 4% + gibberellic acid 2.5 mg l-1 treatment (8.78 ml g-¹ F.W.).
Silver nanoparticles 5 mg l-1 + sucrose 4% + gibberellic acid 2.5 mg l-1 had
highest fresh weight per day (24.89 g) and dry weight (4.96 g), respectively.
