Abstract
In this study, six different growing media (peat+pumice: 1:1, v/v; peat+perlite: 1:1, v/v; rice hull+pumice: 1:2, v/v; coarse sand+peat: 2:1, v/v; soil; and cocopeat) were evaluated for their effects on the plant growth and flower quality of the oriental ‘Siberia’ and ‘Vespucci’ lily varieties. Seven hundred and twenty bulbs were planted in perforated plastic crates and placed in an unheated greenhouse. The physical and chemical properties of the growing media were examined. The number of days to flowering, plant height, the number of flowers, fresh stem weight, the number of leaves and vase life were investigated in the study. The results indicated that the use of soilless growing media significantly affected plant growth and flower quality when compared with soil. The obtained values varied by substrate type. The earliest flowering time (154.78 d) and the longest plant height (120.82 cm in the ‘Siberia’ variety) were determined in peat+pumice, whereas the largest number of flowers (7 flowers in Siberia; 5.67 flowers in Vespucci) and the highest stem weight (266.13 g in Vespucci; 353.91 g in Siberia) were recorded in cocopeat. The vase life of the plants grown in soil was longer than that of the plants grown in the soilless culture. Regarding the number of leaves, rice hull+pumice (57.42 leaves) and sand+peat (54.46 leaves) gave the best results.

Highlights
Genus ‘Lilium’ belongs to the Family ‘Liliaceae’, which comprises over 180 species[1]
The objective of this study is to evaluate the effects of different media on plant growth and flower quality in order to improve the production of cut flower lilies
Rajera et al.[19] tried the cultivation of 2 varieties of LA hybrid lily bulbs in 7 different growing media. They discovered that M7:M1 and vermicompost+cocopeat (2:1:1, v/v) yielded the best result in terms of flowering time, the number of leaves per plant, the number of flowers per plant, stem weight, and vase life
Summary
Genus ‘Lilium’ belongs to the Family ‘Liliaceae’, which comprises over 180 species[1]. Lilium consists of thousands of cultivars that are classified in different hybrid groups and it is one of the most popular ornamental bulbous flowers throughout the world[2]. With 297.2 million units, Lilium ranked 6th among the most sold cut flower species in the auction in the Netherlands[4]. Lilies are usually produced in the field or the greenhouse with a soil or soilless culture medium. Soil-borne diseases and pests are two of the most important problems encountered in the cultivation of cut flower Lilium. Soilless culture has become the preferred technique in ornamental plants among the new growing methods. The properties of the growing media used in the soilless culture either directly or indirectly affect yield and quality
