| 摘 要： | 通过细胞组织学解剖方法 ,观察研究梭梭幼嫩光合枝显微结构的抗逆性特征 ,并结合 H2 O2 酶活性的测定 ,得出梭梭光合枝显微结构中有 3点与相关文献报道不同。 1是具有一层海棉组织 ,富含叶绿体 ,细胞体积相对较小 ,为不规则圆球状细胞层 ;2是退化的鳞片状叶表皮层下仍有一层细胞体积小 ,圆形 ,具有明显的细胞核 ,无叶绿体 ,排列紧密的细胞层 ;3是栅栏组织细胞具泌盐的功能 ,并有发育较好的盐结晶存在于细胞之间 ,显示出较强的抗逆特征。

| Abstract: | The observations on the photosynthetic branch of H.ammodendrom (C.A.Mey) Bunge. The microphotos of H.ammodendrom (C.A.Mey) Bunge show:1.There is layer spongy tissue cell under the patisade tissue of H. ammodendrom leaf;2.There is a layer small, spherical cell tissue under the epiderm of H.ammoderdrom leaf;3. There is the microstructure of secretion salt and good salt crystal body among polisade cell. |
