Abstract:
Objective: To screen higher value Dendrobii strains for development and utilization, the growth vigor and active ingredient contents of nine annual Herba Dendrobii seedlings (T5, T3, T2, YD-1, W-3, GDYS, TN, W-1, and T4) were studied. Methods: The growth and active ingredient contents were measured by the physiological and pharmacognosical methods. Cluster analysis was carried out by SPSS11.5 statistical analysis software. Results: The most desirable growth was T4 while that of T2 was the worst, and the other strains were between them. The nine different strains could be divided into three groups by cluster analysis: The first group included GDYS, TN, T5, and T4, in which the most of the active ingredient indicators were similar and higher than other strains. The second group included W-3, YD-1, and T3, in which there were the second average contents. The third group included W-1 and T2, in which there were lower contents in most active ingredients. Conclusion: GDYS, TN, T5, and T4 could be produced in large scale as good strains, while W-3, YD-1, T3, and T2 could be conserved as germplasm resources, but unfavorable to grow in large scale. The strain of W-1 has a higher content of alkaloids and ash, which could be used as the special extracting materials or the backcrossed parents to improve the individual unfavorable traits of good strains.
