Abstract
An investigation entitled “Study on ideal tree canopy and seasonal effect on growth, flower yield, oil yield and quality of Ylang ylang (Cananga odorata Hook. F. and Thomson.)” was undertaken at aromatic crops field and quality analytical laboratory, Department of Horticulture, University of Agricultural Sciences, GKVK, Bengaluru, during June 2021 to May 2022. The field experiment was laid out in the Factorial Randomized Complete Block Design consisting of twelve treatments replicated thrice, to study the effect of different levels of heading back (3, 4 and 5 feet) and floral bud inducer spray (control, 2, 3 and 4 %) on growth and yield parameters. The analysed pooled data revealed that trees headed back at 3 feet and sprayed with 2 % potassium nitrate
produced maximum number of secondary branches per tree (109.22), number of leaves per tree (12550.29), number of flowers per tree (4383.29), length of green flower (8.68 cm) and yellow flower (8.96 cm), weight of green flower per tree (3812.31 g), weight of yellow flower per tree (2532.65 g) and oil yield (50.5 ml). The lab experiment was conducted to study the effect of
distillation frequency (0, 3 and 6 hours after harvest) and stage of harvest (green and yellow) on oil recovery and composition. The analysed pooled data indicated that yellow flowers distilled 3 hours after harvest had maximum oil recovery (1.34 %). Linalool which determines quality of Ylang-ylang oil was found maximum (33.31 %) in yellow flower distilled 6 hours after harvest
during Rabi season.
