In order to find the factors affecting seed vitality in Carya Nutt,the change rule of Carya Nutt seed germination rate with storage time prolongation under different storage conditions was researched.The factors affecting seed vitality were discussed from the aspects of water content in seed,catalase content in seed,relative conductivity of lixivium from seed,and so on.The results show that the factors of seed germination rate,water and catalase contents in seed,are decreased with storage time prolongation.Relative conductivity of lixivium from seed is increased with storage time prolongation.Seed germination rate has very significantly positive correlation with water and catalase contents in seed,and has very significantly negative correlation with relative conductivity of lixivium from seed.
