Abstract:
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 determine 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 determined 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 III, 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.
