Abstract
This research was conducted as completely randomozed design including two experiments for the first time. The effects of four levels of chitosan (0% plus 2% sucrose, 0.05% plus 2% sucrose, 0.1% plus 2% sucrose and 0.2% plus 2% sucrose), 2% acetic acid plus 2% sucrose and distilled water (control) as presevative solution method was investigated on some qualitative and physiological characteristics of anthurium cut flower in the first experiment. In the secound experiment, the effects of three levels of chitosan (0.05% plus 2% sucrose, 0.1% plus 2% sucrose and 0.2% plus 2% sucrose), acetic acid plus 2% sucrose and distilled water (control) as spray method was evaluated. Results showed that the maximum vase life was observed by chitosan treatments 0.2% plus 2% sucrose in two methods. 0.2% chitosan plus 2% sucrose treatments as preservative solution increased vase life more than 2.5 folds (50 days) in comparison with control. In spray method, vase life enhanced two folds (35 days) in compared with the control, too. The maximum and minimum ion leakage was obtained in acetic acid plus 2% sucrose and 0.2% chitosan plus 2% sucrose treatments in preservative solution method, respectively. In addition, the highest and lowest ion leakage was observed in 2% sucrose and 0.1 and/or 0.2% plus 2% sucrose chitosan treatments in spray method, respectively. In conclusion, in according to environmentally friendly of chitosan the application this compound for extending vase life of anthurium cut flowers are suggested.
