| 摘 要： | 为了适应衰老器官内大量的降解物质在短期内迅速转移到贮藏器官和生长部位，胞间连丝内部结构在酶的作用下瓦解，其周围的细胞壁物质也被降解，胞间连丝结构拓宽，形成胞间通道。

| Abstract: | Transfering and reuse of organic substances in senescent organs rely on the transport and regulation of plasmodesma and cell wall surrounding plasmodesma which are disintegrated by digesting enzymes.Thus,the plasmodesmata are modified and enlarged,a wide intercellular channel is formed by plasmodesmal secondary modification. |

| Keywords: | Plasmodesma Enlargement and modification of plasmodesma Intercellular channel Material transport |
