Abstract
To evaluate the beneficial impacts of different species on mint, some yield characters were investigated. Our objective in this research was the studying of different species effects on essential oil variations. In this respect, the experimental unit had designed by achieved treatment in completely randomized block design with three replicates. The factor including mint species (Mentha longifolia var. amphilema (from Qazvin and Ardabil localities), Mentha spicata (from Tehran and Yazd localities), Mentha piperita (from Tehran and Ardabil localities), Mentha aquatica (from Gheilan and Ardabil localities)) at Iran was studied. Our final statistical analysis was indicated that mint species significantly affected essential oil yield of leaves, essential oil percentage of leaves and leaf yield (P < 0.01) and leaf length (P < 0.05). M. longifalia var. amphilema from Ardabil locality were provided highest essential oil yield of leaves (25.13 kg/ha) and essential oil percentage of leaves (1.64%). Longest leaf length (4.01 cm) was achieved by M. piperita from Tehran locality and highest leaf yield (914.4 kg/ha) was obtained by M. aquatica from Tehran locality. Our findings indicated that were significant difference between essential oil variations of mint species. Therefore, the selection of species that performs well over a wide range of environments can increases essential oil yield of medicinal and aromatic plants.
Key words: Mentha species, essential oil yield of leaves, essential oil percentage of leaves, leaf yield.
