Abstract

We investigated the seed production of Styrax tonkinensis from 3～5 year old plantation and the seeds'edible value in Luxuling Forest Farm in Jiangxi Province.It showed that the tree of Styrax tonkinensis may begin to fruit after planted in 2 years.The seed production in the third year of plantation reached av.2～2.5 kg per tree;owning to stands'closure after 5 years of that,its seed production reduced to av.1.05 kg per tree.The commercial seeds might produce oil at 21% of weight.The oil from seeds of Styrax tonkinensis comprise rich nutrition;of its fatty acids,the total content of unsaturated fatty acid reached as high as 85.4%.Thus we considered this tree was a good candidate for excellent edible oil producer.
