摘要
对驯化栽培3年的湖北野生石蒜(Lycoris radiata Herb)的生物学特性及形态解剖构造进行了研究。结果表明,由于驯化栽培石蒜与野生石蒜的生长环境存在显著的差异,从而使二者在生物学特性、外部形态和解剖构造方面产生了一定的差异,表现为驯化栽培3年后的野生石蒜抽薹期、盛花期和衰败期提前;叶面积缩小而叶的数目以及鳞茎直径和鲜重增加;叶上下表皮细胞、气孔直径明显减小,气孔密度明显增加。
The domestication of wild Lycoris radiata Herb was studied on biological,morphological and anatomical characteristics.The results indicated that there was a certain difference between the populations of the wild and the domesticated L.radiata because of their different habitats.The bolting phase,flowering phase and flower overripe phase of L.radiata,which was domesticated and cultivated for 3 years,became earlier.The leaf area was smaller than that of wild L.radiata,while the number of leaf,bulb diameter and fresh weight increased.At the same time,the epidermis cell of leaf and the stoma diameter became smaller in the domesticated population with a higher stoma density.
