摘要: 对单优种羊草种群的演普及演化规律的分析表明,黑钙土型羊草植物体结构简单,盐碱土型羊草结构复杂,演化出进化程度较高的通气组织、保护组织、薄壁组织及输导组织等.研究结果表明,不同土壤型羊草具有明显的种内差异.

Abstract: The analysis of succession and evolution patterns in single excellent species of Aneurolepidium chinense shows that the morphological structure of A.chinense on chernozem-type soil is simple, and that on saline-alkaline soil is complex,which consists of higher evoluted tissues,i.e.aerenchyma,protective tissue,parenchyma and conducting tissue etc.The results show that A.chinense on different soil types has significant intraspecific difference.
