It was observed that the influence of bud and its position on the healing process of grafting unions using hardwood sectioning method, and found that:(1) bud of a scion and its position to the graft unions have no influence on callusing formation of the isolation layers, and the early differentiation of cambia;(2) a scion bud closer to the grafting union would promote the formation of more compacted callus cells and the earlier formation of callus bridges;(3) conduit differentiation in grafting unions of lower-bud scions was later than that of other treatments.
利用滑动切片法对芽子有无及芽位对嫁接愈合过程的影响进行了观察,发现:(1)接芽有无及芽位对隔离层及愈伤组织形成和形成层的早期分化没有影响;(2)芽或去芽的芽位距接口近,可以促进愈伤组织的紧密连接,即愈伤组织桥的形成;(3)低位芽枝嫁接体中导管分化较晚,而其它处理导管的分化几乎是同时发生的,而且导管首先出现于愈伤组织薄壁细胞中。

A series of grafting-modified dregs were prepared and the influence of monomer ratio, rotation speed and time of ball milling on grafting efficiency was investigated. It is demonstrated that mechanochemical techniques of ball-milling can smash up dregs as well as initiate in-situ grafting polymerization. Thus the usableness and uniform dispersion of dregs in polymer matrix can be ensured.
