Effects of Auxin and Media Culture on the Production of Lily (Lilium spp.) Bulblet Using Scaling

Lily (Lilium spp.) is one of the most popular geophyte ornamental plants of cut flowers in Iran and the world. The country’s dependence on the import of bulb and following that high price and lack of easy access to the quality bulbs are the main problems for producers of lilies cut flower in the country. For this purpose, the objective of this study was to optimize the production of bulblets as the first stage of bulb production. The factorial experiment was performed in a completely randomized design with three replications and eight scales per replicate. Experiments were as follow: (I) five levels of auxin [control (distilled water), 250 and 500 mg/l indole-3-butyric acid, 250 and 500 mg/l naphthalene acetic] for one hour, (II) Three levels of media culture [Cocopeat, Cocopeat + Perlite (1:1) and Black Peat moss]. The results showed; the maximum number of bulblet (2.07) in the treatment of indole-3- butyric acid 500 mg/l [Non significant difference with treatment 250 mg/l naphthalene acetic acid], more the highest bulblet weight (0.81 g) and bulblet diameter (1.32 cm) in the control treatment, the maximum number of root (4.37) and root weight (0.60 g) in the treatment indole-3-butric acid 250 mg/l, the highest bulblet production percentage (75.55%) [Non significant difference with treatment control] were obtained.
