Abstract:

Clitoria fragrans pigeon wings, is a limited seed producer and a federal-ly listed threatened plant. Therefore, we conducted a greenhouse study to determine whether C. fragrans can be propagated vegetatively from xylopodia and whether growth hormones can enhance propagation success. This information could be used to maintain population viability in the future. For this study, we collected mature plants from the field, transplanted them in the greenhouse, and harvested xylopodia from the root system. We treated the xylopodia with indole-3-acetic acid IAA or indolebutyric acid IBA at concentrations of 0, 250, 500, 1000, and 2000 mgL for the lateral root xylopodia and at 0 and 1000 mgL IAA for the terminal xylopodia. We observed the xylopodia for 114 days for signs of root growth, newly developed shoots, mold, and rot. Lateral xylopodia controls and those treated with IAA produced new plants, though propagation was inversely proportional to the treatment level of IAA. Two of the nine treated terminal xylopodia produced new plants. No plants were propagated from the IBA treatments. Propagating C. fragrans is possible and has potential to be a viable method for reestablishing the plant in the field. A total of 19 plants were produced in this study from only two initial C. fragrans plants.
