A Study of Seedling Raising and Grafting Reproduction of Magnolia liliflora Desr

Tests of seedling raising and grafting reproduction of Magnolia liliflora Desr were conducted in Beichuan County during 2004～2006.The results showed that the effect of seedling raising was best at an elevation of 600m and the one-year-old seedlings were 70.60cm in height and 0.75 cm in ground diameter and 16.00% in grafting rate.There was a strong negative correlation between the elevation and the seedling-forming rate.There was no significant difference in seeding breeding in spring or autumn.But there was a significant difference in seeding by traditional reproduction and standardization reproduction.The one-year-old seedlings were 76.97cm in height and 0.76 cm in ground diameter and 16.33% in grafting rate by standardization reproduction,but the one-year-old seedlings were 17.2cm in height and 0.29cm in ground diameter and 0% in grafting rate by traditional reproduction.There was a significant difference in grafting time and seedling rate.The seedling rate was very high in autumn,coming to 96.50% and 91.30% in September and October respectively.
