Different Amino Acids Inhibit or Promote Rhizome Proliferation and Differentiation in Cymbidium goeringii

The proliferation and differentiation of rhizomes are crucial for the propagation Cymbidium species. We systematically assessed effects different concentrations 20 amino acids on C. goeringii rhizomes. Rhizome rates were significantly higher in media with 2.0 mmol·L −1 cysteine, 0.5 arginine, 0.2 asparagine, 1.0 proline, lysine compared those control. Additionally, tyrosine, aspartate beneficial rhizome differentiation. Furthermore, two combinations acids, arginine + proline resulted 3.05 3.01, respectively, after 60 days. highest rate (5.39 days) was observed asparagine aspartate. This study demonstrated that certain can effectively promote during rapid goeringii.
