摘要
探讨了砧木种类、砧木年龄以及砧木地径等对广东含笑嫁接育苗的影响,结果表明,不同砧木嫁接成活率差异不显著,均达80%以上,其中以1 a生黄兰为砧木的嫁接成活率最高,为88%。砧木种类、砧木年龄及砧木地径均显著影响嫁接苗的生长,以2 a生火力楠为砧木嫁接广东含笑效果最好,其嫁接苗长势明显优于其他砧木的嫁接苗。研究还表明,接穗的高生长与砧木地径呈正相关关系。
The grafting experiment of Michelia guaagdongensis were carried out w^ta amerem KlnOs, a^e class and ground diameter of rootstocks. The grafting survival rates of different rootstocks were more than 80% , without significantly differences. The highest survival rate was 88%, using one-year-old Michelia champaca seed- ling as rootstock. The kinds, age class and ground diameter of rootstock had an obvious effect on the growth of Michelia guangdongensi grafting. The seedling using two-year-old rootstock of Michelia macclurie performed better than the other rootstocks. Meanwhile, it＇s found that there was a positive correlation between the height of scion and the size of ground diameter of rootstock.
