利用扫描电子显微技术对松嫩平原的羊草(Aneurolepidium chinense)、獐毛(Aeluropus litoralis)、星星草(Puccinelliateninflora)、朝鲜碱茅(P.chinampoensis)和野大麦(Hordeum brevisublatum)等5种耐盐碱牧草进行解剖结构研究,发现它们适应盐碱环境而演化出的各种特殊的结构特征,即:根的皮层薄壁组织形成大的通气腔(其形如水生植物的通气腔),茎中维管束演化出近散生结构,叶上表皮泡状细胞和气孔下陷,叶脉维管束鞘不为C_3植物型亦不为C_4植物型,而演化出C_3—C_4的中间类型。
A total of five species of Aneurolepidium chinense, Aeluropus litoralis, Puccinellius inflora, P.chinampoensis and Hordeum brevisublatum on the Songnen Plain were detected by scanning electron microscopy Saline-alkali pasturage was anatomically studied and found to adapt to various salient features of the saline-alkali environment, ie, the parenchyma of the root forms a large aeration chamber (shaped like the aeration chamber of an aquatic plant) and the stem The vascular bundle evolved into a near-disastrous structure, the epidermal bubble cells and stomata subsided, and the vascular bundle sheath was not C_3 plant type nor C_4 plant type, but evolved the intermediate type of C_3-C_4.
