The results showed with the increasing of NaCl concentration, the phenomenon of carnification could be found in the leaves of Arabidopsis thaliana . Under the stress of NaCl lower than 100 mmol/L, the tissue structure of root had no distinct difference from the control. When the concentration of NaCl was higher than 250 mmol/L, the stained color of safranine was deep but not even, and color in fibrovascular tissue and peripheral cortex cell were deeper than that around fibrovascular tissue.

当NaCl浓度小于100 mmol／L时，根组织结构与对照未表现出明显的差异；但当NaCl浓度达到250 mmol／L时，根组织结构对番红染料的着色较深而且不均匀，维管组织和外围皮层细胞着色较深，而维管组织周围的细胞着色较浅。

Six days after inoculation, the cucumber root tip was slightly swollen and symmetrical root-knots were observed at the meristematic and elongation zones. Giant cells were differentiated by previous cambium cells in the center of the root; 10days after inoculation, symmetrical and secondary root-knots were observed at the root hair and upper zones. Vessels were separated by giant cells, around which protoxylem vessels were observed; l6days after inoculation, hypo-vascular tissue appeared earlier than normal; 20-30 days after inoculation, the vertical arrangement of vessels was disordered, shape was distorted and a new vascular tissue appeared in the cortex.

测定出叶片表皮细胞、角质层和厚角组织厚度，表皮毛、气孔器和叶内组织的类型、大小等；测定出茎的表皮细胞厚度，表皮毛的类型和密度，皮孔密度，皮层、栓皮层、维管组织和髓的厚度，计算皮层与半径之比，维管组织与半径之比，髓与半径之比等。

In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.

结果表明：鹅掌楸亚科和木兰亚科在叶的结构上的主要区别是鹅掌楸亚科两种植物叶的部分下表皮细胞呈乳突状，且整个细胞外壁只形成一个乳突，而在木兰亚科的植物中有单列多细胞或单细胞的表皮毛，未发现乳突；鹅掌楸亚科植物的叶主脉维管组织环分隔呈束状，且其外包被的纤维也排列成束状，而木兰亚科的80种1亚种植物中，叶主脉维管组织连成轮状，其外面也由一圈连续的纤维环所包围。
