A Preliminary Report on Walnut Seed Seedling Raising Tests in Panzhihua

In this experiment,walnut seeds were sown in autumn and spring.And the seed treatment ways included the four methods such as soaking with warm water (40℃~45℃),soaking with room temperature water,sand storage,and untreatment,aiming to conduct the germination contrast experimental study.The results showed that in the autumn sowing and by use of sand storage and room temperature water treatment,the germination rate and seedling growth of walnut seeds were significantly better than those by use of other treatments,and the wanut seed had the highest germination rate by use of room temperature water treatmut reaching 93.98%,and the seedling emergence time necded about 50 days.So,the walnut breeding in Panzhihua shoud adopt a timely manner,and the autumn sowing,the use of room temperature water and sand storage method showd be the best.
