Abstract
To evaluate the effect of putrescine and salicylic acid on the quality and durability of cut flowers carnation White, an experiment in a completely randomized design with two factors putrescine in 3 levels (0, 150 and 300 mg/L) and salicylic acid in 3 levels (0, 150 and 300 mg/L) with three replications. The results showed that at 12 days after the beginning of experiment, the highest electrolyte leakage petals of control treatment, salicylic acid 69.67% and the lowest level of 150 mg/L of salicylic acid was 5.00%. In 24 days after the beginning of experiment, treatment with 300 mg/L putrescine highest relative water content petals (79.33%) and 150 mg/L of salicylic acid lowest relative water content (0.001%) was registered. In 35 days after the beginning of the experiment control putrescine, the highest relative water content (68.00%) and putrescine treatments of 300 mg/L and 150 mg/L salicylic acid and salicylic acid lowest relative water content (0.001%) showed. The highest flower longevity of flowers from treatment with 300 mg/L putrescine (19.00%) and the lowest treatment with 300 mg/L of salicylic acid (12.00%) was observed. The highest chlorophyll content of 150 mg/L putrescine (5. 47 mg /g tissue) and the lowest in the treatment with 300 mg/L of salicylic acid (2.13 mg/g tissue) was observed. In 23 days after the beginning of the experiment, the results showed that the levels of putrescine and salicylic acid, the highest solution uptake treatment with 300 mg/L putrescine and the lowest is putrescine control treatment. Therefore, treatment with 300 mg/L of putrescine to increase longevity and quality of cut flowers cloves recommended.
