[Seedling quality and root rot on Panax notoginseng].

The experiment was carried on the relationship between seedling quality and root rot on Sanqi (Panax notoginseng). The result showed that seedlings from new reclamation land, the root rot disease was fewer and existing rate of seedling was higher than that of seedlings from old gardenplot. Therefore, selecting ill-free and robust seedling is one of important measure for the control of root rot on Sanqi cultivation.
