摘要：The Tulip Collection of Horticulture Department, University of Pitesti was founded in autumn 2008, with 35 species and 253 varieties. The bulbs were purchased from a certified facility for production and marketing of propagating material, to assure the authenticity of species and varieties. For each species and variety were planted 10 bulbs, following the bulbous planting technological sequences: depth 10 cm, distance between bulbs/row – 10 cm, distance between rows – 25 cm and numeric labeling. To eliminate the risk of bulbs' damage, they are removed from the soil every year, are sorted, treated and stored properly
