Comparison on Seed Traits of Different Natural Typesof Torreyagrandis in Pan’an

Seeds of 11natural typesof Torreyagrandis andT. grandis‘Merrillii’were collected in Pan’ancounty of Zhejiang province in September of 2016. Determinations and analysis were carried out on seed traits, such as single fruit/nut/kernel mass, nut verticle/cross diameter, and content of protein/total sugar, fatty acid composition, etc. The results demonstrated that there was extremely evident difference of seed traits among tested ones. The single mass of seed (nut,kernel) among determinedtraits had the largest variation coefficients,followed by the index of nut shape, index of seed shape, arilthickness. HeheXiangfei had the largest species richness variation.
