This experiment was conducted to evaluate the effect of four types of nutrient solutions on growth, quantitative and qualitative characteristics of Lilium cut flower (Lilium LA Hybrid Fangio) in soilless culture in a completely randomized design with four treatments, four replications with 10 pots per replicate in the research greenhouse of the University of Guilan. Plants with four treatments of macro elements(S1, S2, S3 and S4 highest to lowest macro elements,respectivly) were arranged on the base of modified Quick nutrient solution with different salts including potassium nitrate, di potassium hydrogen phosphate, potassium dihydrogen phosphate, calcium nitrate, ammonium nitrate, calcium chloride and Magnesium sulfate mg/L. All macro elementscontained similar amounts of micro-elements. Results showed that there were significant difference between different treatments of macro elements for length of bud, leaf length and width, number of leaves, daughter bulb weight, total chlorophyll content of leaf, anthocyanin and petal protein, leaf nitrogen, potassium, phosphorus and magnesium. Also, significant difference was not observed for traits such as plant height, number of flowers, number of days to flowering, number of daughter bulb, proline content, ion leakage, leaf relative water content and lipid peroxidation in leaf. Results of mean comparison of data showed that S1 treatment, had the highest concentrations of macro elements, had a positive effect on vegetative characteristics such as length of largest flower bud, leaf length and width, leaf number and weight of daughter bulb as well as biochemical parameters like anthocyanin and protein in petal, chlorophyll in leaf, and concentration of mineral elements of nitrogen, phosphorus, potassium, calcium and magnesium in the leaf of lily cut flower in soilless culture conditions.
