Effect of rootstocks on quantity and quality of essential peel oil of 'Kinnow' mandarin (Citrus reticulata Blanco)
A quantitative and qualitative study was designed to check the effect of various rootstocks on peel essential oils of Kinnow mandarin.
Eight different rootstocks, i.e., Mithi (Citrus jambhiri Lush.), Volkamariana (C. jambhiri Lush × C. volkamariana), Yuma citrange (P. trifoliata (L) Raf × C. sinensis (L) Osbeck), Brazilian sour orange (C. aurantium L.), Rough lemon (C. jambhiri Lush.), Troyer citrange (P. trifoliate (L) Raf × C. sinensis (L) Osbeck.), Citrumelo 1452 (P. trifoliate (L) Raf × C. paradisi Macf.) and Citrumelo 4475 (P. trifoliate (L) Raf × C. paradisi Macf.) grafted by Kinnow mandarin were evaluated.
Quantitatively, the extracted citrus peel essential oils ranged from 6.47 to 22.76 mL, with a quantitative difference of 16.29 mL between the selective rootstocks.
Maximum peel essential oils were depicted by rootstock Mithi (31.76 mL), followed by Troyer citrange (28.45 mL). Gas chromatography of peel samples of Kinnow revealed five volatile compounds (β-terpinene, myrcene, citronellyl acetate, citral and citronol) in Mithi, Volkamariana, Yuma citrange and Brazilian sour orange; four compounds (β-terpinene, linalool, citronellyl acetate and limonen) in Rough lemon and Troyer citrange; single compound of limonene in Citrumelo 1452 and limonene and piperonaldehyde were identified separately in Citrumelo 4475. It can be concluded from the findings that rootstock has a profound effect on the amount and composition of peel essential oils of Kinnow mandarin.
