Introduction and Cultivation of Six Varieties of Lavandula × intermedia in Fuyang Area
In order to explore the ecological adaptability and application potential of lavandin(Lavandula × intermedia)in Fuyang area,six introduced varieties of lavandin were investigated and analyzed in the third year of planting,including growth indicators such as plant height,crown width,number of flower branches,ornamental indicators such as leaf color,flower color,flowering period,and economic indicators such as essential oil content,composition,and unit yield.The results showed that all varieties could grow normally in Fuyang area,and the plant height of'Mentha'was the highest among the six varieties,reaching 81.30 cm;'Sumian'had the largest crown diameter,reaching 114.25 cm;and'Nizza'showed the largest amount of flowers,with a dry weight of 252.63 g/plant.Besides,deep calyx and corolla colors were observed in'Arabian Nights'with the earliest flowering and the longest ornamental period.According to economic indicators,'Arabian Nights'had the highest extraction rate of essential oil,reaching 5.34％,and'Nizza'had the highest yield of essential oil,reaching 9.22 g/plant.Gas chromatography-mass spectrometry(GC-MS)analysis showed that the content of linalool and linalyl acetate in the essential oil of variety'Nizza'was the highest and the quality was significantly superior to other varieties.In summary,among the six lavandin varieties,'Arabian Nights'is most suitable for ornamental cultivation,and'Nizza'is the most suitable variety for essential oil extraction cultivation in Fuyang area.
