胡桃楸 ( Juglans mandshurica Max-im.)材质工艺性能极好 ,是建筑、军工等重要用材。其种子富含不饱和脂肪酸 ,是珍贵的保健食品。因其被大量采伐 ,资源日趋枯竭。体细胞胚胎发生是快速繁殖和人工种子研制的基础 ,对遗传改良有重要意义。迄今 ,未见到胡桃楸体细胞胚胎发生获得 Juglans mandshurica Max-im. Is an excellent material with excellent processability and is an important material for construction and military applications. Its seeds are rich in unsaturated fatty acids, is a precious health food. Due to its heavy harvest, resources are depleting. Somatic embryogenesis is the basis for the rapid propagation and development of artificial seeds and is of great importance to genetic improvement. To date, no Juglans mandshuroe embryogenesis has been reported
