研究了靖西广豆根种群营养器官的生态解剖结构及其与岩溶环境协同进化。结果表明:靖西广豆根具有良好适应干旱、高温岩溶环境的生态结构,保护组织、输导组织、光合组织、机械组织和薄壁组织等都产生较大程度的进化,意味着具有多样性的应对胁迫的遗传基因,具有良好的自我生存机制。同时,各种组织的进化不是全面的,大多数表现为一种细胞的进化,保护组织表皮的角质膜厚,表皮毛多;叶肉的栅栏组织3层;输导组织和机械发达源于发达的维管束;薄壁组织发达,但没有专门的贮水组织。仅能生长在具有一定植被的岩溶环境。对于“石漠化”极为严重的整体环境,要有效保护靖西广豆根,必须加强引种驯化、封山育林、生态恢复,严格控制采集量,建立多区域生态保护斑块。
The ecological anatomical structure of vegetative organs of Quercus fabri in Jingxi and their symbiotic evolution with karst environment were studied. The results showed that the broad-bean root of Jingxiu had a good ecological structure adaptable to arid and high-temperature karst environments. The protective tissues, the transport tissues, the photosynthetic tissues, the mechanical tissues and the parenchyma all had a large degree of evolution, which meant that they had diversity The response to stress genes, has a good mechanism of self-survival. At the same time, the evolution of various organizations is not comprehensive, most of the performance of a cell evolution, the protection of the epidermal keratinocytes thick, epidermal hair more; mesophyll palisade tissue layer 3; guide the organization and machinery developed from the developed Vascular bundle; parenchyma developed, but there is no special water storage organization. Can only grow in a certain vegetation karst environment. For the extremely serious “rocky desertification” environment as a whole, in order to effectively protect the broad bean root of Jingxi, we must strengthen the introduction and acclimation, seal off the afforestation, restore the ecosystem, strictly control the collection volume and establish the multi-region ecological protection patches.
