摘要
对金线莲种苗的株高、地径、叶片数、全株鲜重和高径比5个形态指标进行检测,并进行主成分分析确定分级指标,采用逐步聚类分析方法聚类分级;进行不同等级种苗盆栽试验,对植株生长指标,药材产量和品质指标进行测定。结果表明可以选用株高和地径为种苗分级的质量指标,并初步制定了金线莲种苗质量分级标准;不同级别金线莲种苗对植株生长发育,药材产量有影响,Ⅰ级苗的株高和地径要比Ⅱ级、Ⅲ级苗高,且药材产量也显著高于Ⅱ级、Ⅲ级苗药材产量,而对药材内在品质无明显影响,为金线莲规范化栽培提供依据。
The morphological index of the seedlings including the plants height, the ground diameter, the leaf amounts, the fresh weight of the whole plant and the ratio of height to diameter was measured and the principal components were analyzed so as to de- termine the grading index, and stepwise cluster analysis was applied for clustering analysis. Pot experiments were used to measure the indicators of plant growth and development, the yield and the quality. The results showed that the height and ground diameter were de- termined as the quality indicators of the seedlings grading and the standard quality grading of seedlings of Anoectochilus roxburghii was initially set up, different seeding plants influenced the plants growth and the yield. The ground diameter of the class I was larger than that of the class II and llI, so as the yield. The seedling grading had no obvious effect on the internal quality of medicinal materials. The results of the study provide the basis for standard cultivation of A. roxburghii.
