Abstract: The five years old ‘Changlin 4’ oil-tea camellia was selected to study the effect of different canopy position on fruit characteristics. The results showed that the fruits bearing upper outside the canopy, which average weight was 29.5 g and average number of seeds was 4.8, were both higher than that inside the canopy. While the fresh ratio of seeds and fruit shape index of the fruits bearing upper outside the canopy were lower, which was 46.8% and 0.81 respectively. The oil content ration in seeds of fruits bearing upper outside the canopy was 41.2% (α=0.05) which was significantly higher than that bearing inside the canopy. And no difference of oil content ration in seeds was found among fruits bearing on the different position of outside canopy. In addition, the fat acid composition of seeds was not significantly affected by different bearing position in canopy, and the quality of tea oil was also not influenced by growth zone of fruits greatly.
