Discovering adventitious roots in Glycine tomentella Hayata: lack of adventitious roots as a morphological and taxonomic species indicator is worth considering.
Glycine tomentella Hayata is characterized by a lack of adventitious roots. In China, G. tomentella is distributed only on the southeastern coast. Here, 59 G. tomentella natural populations on the islands and coasts in Fujian and Guangdong Provinces were morphologically investigated. We discovered G. tomentella (2n=80 tetraploid) having adventitious roots existed ubiquitously along the southeastern coast of China. Fasciated stem variation was also discovered in populations at three sites.
