5 layer number of cortical cells in stem was n ' t changed evidently , however the ratio between cortical thickness and stem increased as well as the ratio between vascular cylinder and stem , up the gradient of nacl concentration . 6 stem dm of suaeda salsa remarkably decreased with increasing nacl concentration , so did the vessel dm of xylem in the stem ( 5 )隨鹽濃度的增加，莖皮層細胞層數未發生明顯的變化，但皮層厚度所占莖的比重增加，維管組織占莖的比重同皮層厚度與莖半徑的比值表現出相同的趨勢。 |

We have observed the following characteristics of anatomical structure and development : ( 1 ) the primary roots belong to archetype and the lateral roots occur in the position toward the xylem of the vascular cylinder ; ( 2 ) the root endodermis consists of thicken casparian strips , and there are from two lo four layers parenchyma cells near the pericycle ; ( 3 ) the pith and resins canals are absent in the toots ; ( 4 ) secondary structure occurs in the root hair zone , and vascular cambium is formed from the parenchyma cells between the primary xylem and primary phloem ; ( 5 ) tanning materials are abundant in pericycle cells and phelloderm cells ; ( 6 ) sclereids are found in secondary phloem , and rays are rather rich in secondary xylem 結果表明：氣生不定根具有以下結構特征和發育特點： ( 1 )根為二原型，側根正對著木質部發生； ( 2 )幼根內皮層細胞具凱氏帶加厚，維管柱內緊挨中柱鞘內側具有2 ~ 4層大型薄壁細胞； ( 2 )根中無髓和樹脂道； ( 4 )次生結構發生于根毛區，維管形成層由初生木質部和初生韌皮部之間的薄壁細胞轉化形成； ( 5 )中柱鞘和栓內層細胞富含單寧類物質； ( 6 )次生韌皮部有石細胞，次生木質部射線發達。 |

Leaf gap ( lacuna ) a region of parenchyma differentiated in the stem vascular cylinder immediately above a diverging leaf trace . lateral connections insure no break in the vascular system 葉隙：葉跡從中柱分出的上方，初生維管柱上方出現的一些薄壁組織細胞，與莖的維管柱結構不同，它的側向連接保證了莖葉維管系統的連續。 |
