Title: DETERMINING LEAF YIELD, SOME PLANT CHARACTERS AND LEAF ESSENTIAL OIL COMPONENTS OF DIFFERENT CULTIVARS OF LAVENDER AND LAVANDIN (LAVANDULA SPP.) ON THE HARRAN PLAIN ECOLOGICAL CONDITIONS
Abstract: This study was conducted to determine the yield and some plant characters of different types of lavender (Lavandula spp.) at Harran University, Faculty of Agriculture, in Şanlıurfa, Turkey, during 2015, with Randomized Complete Block Design with three replications.In the study, 5 different types of lavender [L.angustifolia (Grosso Tina, English cv.) and L. x intermedia (Abriel, Dutch, Grosso cv.)] were used as plant material.This research was determined the plant height (29.30-31.15and 25.47-30.10cm), canopy diameter (47.72-56.86 and 44.33-47.60cm), dry herb yield (91.32-111.80 and 66.17-103.31g plant -1 ), dry leaf yield (68.52-83.11and 53.36-78.99g plant -1 ) and essential oil ratio (0.92-0.99% and 0.87-0.99%) of L. angustifolia and L. x intermedia, respectively.In addition, the major constituents of the essential oils of L. angustifolia and L. intermedia leaves were determined to be 1.8 cineol (33.11-36.19%),camphor (21.04-22.15%)and borneol (7.33-9.63%).
