披麻草生物学特性初步研究

A Preliminary Study of Biological Characteristics of Veratrum Nigrum

目的通过披麻草的植物形态、内部结构和生态适应性等进行生物学特性研究。方法实地调查、观察、测量和植物组织常规石蜡切片法。结果披麻草具有喜凉爽植物的结构和特征;皮层宽广,内皮层明显;鳞茎有多层鳞叶包裹,鳞茎中央维管束和导管丰富;披麻草适于生长在高寒山区,喜凉爽阴湿的环境,忌强光,其土壤以腐殖质壤土或砂质壤土为主。结论披麻草的生物学特性可为合理的开发、利用和GAP规范化种植提供理论依据。

Objective： To study the biological characteristics of Veratrum Nigrum through its plant morphology, internal structure and ecological adaptability. Methods： A field survey was conducted to investigate, observe, measure Veratrum Nigrum and plant tissue paraf- fin section method was used. Results： Veratrum Nigrum has the structure and characteristics of growing in cool areas, broad cortex, clear endodermis, bulb wrapped in multiple layer scale leaves, bulbs with central vascular bundle and rich catheter. Veratrum Nigrum is suitable to grow in the alpine mountains, has preference for cool damp environment and shuns hard light, mainly in loam soil with humus or sandy loam. Conclusion： The biological characteristics of Veratrum Nigrum may provide a theoretical basis for its rational development, utiliza- tion and GAP standardized planting.
