چکیده

Alstromeria is a new cut flower in Iran that due to the high performance, long life, and pretty flowers and colors diversity is highly regarded. Premature yellowing of leaves in cut flowersAlstromeria before petal fall is the most important factor limiting the vase life of flowers. To delay leaf yellowing and increased quality, factorial experiment based on completely randomized design carried out with the two factors thidiazuron (TDZ) (0, 10, 20 and 50 mg l-1) and naphthalene acetic acid (NAA) (0, 10 and 20 mg l-1). Results showed that the maximum vase life and the value of chlorophyll b were achieved (20 mg l-1 thidiazuron 20 mg l-1 NAA) and the most petals proteins was related to treatment 10 mg l-1 thidiazuron and 20 mg l-1 NAA. The most petals carotenoids and dry matter content and the least ethylene production was obtained in 10 mg l-1 TDZ and 10 mg l-1 NAA, respectively.
