PROVENANCE VARIATION IN SEED OIL YIELD FROM Calophyllum inophyllum GROWN IN COASTAL UTTARA KANNADA AND PHYSICO CHEMICAL CHARACTERIZATION OF OIL
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
Studies on effect of provenance on seed oil yield and its physico-chemical characterization of oil of Calophyllum inophyllum, provenance influence on seed oil content and its physico-chemical properties were conducted in Uttara Kannada district (Agro-climatic Zone-10) of Karnataka during 2014-2015. Study was undertaken in the already existing trees in natural forests at five different locations with varying altitudes (2.7-26.6 m) and rainfall (3209-4145 mm). Seed oil yield were highly variable ranges from 36.07 to 48.87 percent. Honnavar sites recorded highest oil yield of 48.87 per cent and the lowest oil yield was recorded in Kumta sites (36.07 %). Sites near coastal area recorded highest oil yield (44.51 %) and sites away from coastal area recorded lowest (42.50 %). The percentages varied significantly among the locations and sites which indicate potential effects of the locality on oil content. C. inophyllum oil was greenish yellow in colour with disagreeable odour. Oil is having kinematic viscosity of 38.17 cSt (at 40 °C), density of 933 (kg/m3 at 30 °C), acid value of 39.6 (mg KOH/g), specific gravity of 0.933 (at 30 °C), free fatty acid content of 34.08, saponification value of 202.71 and iodine value of 93.05.
