Effects of Fruit Maturity and Compost on Oil Yield and Quality of Camellia reticulate

HUANG Jia-cong; KAN Huan; WAN Xiao-jun; YANG Kai-bao

Fruit collection and compost trials were conducted, including four combination treatments of two fruit maturity (eighty percent matured and almost fully matured) with the fruit composted or not, by using 38 superior trees of Camellia reticulata. The oil yield and quality were tested and compared for each tree and treatment. The results showed that there existed significant differences in oil yield and quality among the four treatments, collecting the eighty percent matured fruits led to heavy loss of oil yield, and the ratio of oil in kernel, seed and fruit declined by 11.0, 18.2 and 31.7 percent, respectively, while the oil acid value also deceased by 10.5 percent which was good for oil storage. After compost treatment, the matured fruits were seen that the ratio of oil in kernel declined by 4.5 percent as well as oil acid value increased by 7.3 percent. It was thus concluded that fruit should be collected when matured and seed-husking should be done as soon as possible after fruit collection. These findings will provide technical support for fruit collection and treatment of C. reticulata.
