| 摘 要： | 山楂幼树抽条与休眠期枝条的皮孔、组织解剖构造有关。枝条上皮孔多,早春皮孔打开的早,皮孔结构不严密的品种易失水抽条。木栓层的细胞层少、木质部组织疏松、木质部导管横截面积大,髓部面积与木质部面积之比大,射线面积与木质部面积之比小的品种易失水抽条,反之,不易抽条。

| Abstract: | The desth of branches in hawthorn Young-trees have a close relationshipwith lenticel,anatomy structure of its branch in dormant period.Some ofvarieties were easy to lose water resulting in the death of branches.whichcould be attributed to the large amount of lenticels on the branch and totheir opening in early spring Bisides,such varieties bad loose anatomic str-uctures.The varieties that have less cell-layers of cork-layer,looser tissuesof ligneous tissue,bigger total area or vessel,bigger rate between pith areaand ligneous area,smaller rate between total ray area and ligneous area areeasy to produce died branches. |
