THE EFFECTS OF PUTRESCENCE AND SALICYLIC ACID ON THE QUALITY AND LONGEVITY OF CUT FLOWERS CLOVES (DIANTHUS CARYOPHYLLUS L.)Mehrasa Anvari, Behrooz Salehi and Amrollah Nabigol
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.
