| Abstract: |
| To explore the grafting seedling technology for fragrant resin-producing varieties of Aquilaria
sinensis and obtain the optimal grafting method, a three-factor orthogonal experiment was conducted involving
the scion position, rootstock height, and rootstock thickness to investigate the differences in grafting seedling
rate, seedling shoot length, diameter at the grafting position, leaf growth, and growth performance after afforestation (afforestation survival rate, seedling height, and ground diameter). The results showed that the rootstock ground diameter was the main factor affecting the seedling rate, shoot length, grafting interface thickness,
seedling height, and ground diameter of the grafted seedlings of A. sinensis. The scion position significantly affected the seedling rate and leaf growth of grafted seedlings of A. sinensis (P<0. 01). The effects of rootstock
height on shoot length, grafting interface thickness, and survival rate were significantly different (P<0. 05). The recommended grafting methods for fragrant resin-producing varieties of A. sinensis involved using an upper
scion, a rootstock with a ground diameter above 1. 2 cm, and a rootstock grafting height of 10-12 cm. |
