Factors affecting the grafting survival rate for Ormosia hosiei

The research on grafting was carried out to investigate the effects of five key factors such as grafting methods,grafting time,types of scion,ground diameter of rootstocks and stored time on grafting survival rate of Ormosia hosiei by using 2-year-old container seedlings as rootstocks. The results showed that the influence of various factors on the grafting survival rate was significantly different. In the grafting method test,the best grafting method was veneer grafting,the survival rate of which was 60. 6%. In the grafting time test,the best grafting season was spring,the survival rate of which was 60. 6%,and the survival rate in autumn was55. 0%. In the type of scion test,the best type of scion was semi lignified scion and dormancy bud,the survival rate of which was61. 7%. In the ground diameter of rootstock test,the best ground diameter of rootstock was among 1. 6- 2. 0 cm,the survival rate of which was 55. 0%. In the stored duration test,the optimal stored duration was stored for one day,the survival rate of which was61. 1%.
