Background: Nutrient conditions during plant growth may affect tolerance to abiotic stresses. This study investigated whether the waterlogging stress of ginseng (Panax ginseng C. A. Meyer) is affected by nutrient supply.
Methods and Results: Two-year-old ginseng was cultured under nutrient-deficient (ND), -moderate (NM), and -excessive (NE) conditions, and waterlogging treatment was implemented for 3 days in August. Waterlogging caused the loss of chlorophyll, a decrease in leaf turgor, and withering of the shoots. Waterlogging-induced damage to the shoots was highest under the ND condition, and it was minimal under the NE condition. Photosynthesis and stomatal conductance were decreased by waterlogging under all nutrient conditions, and the maximum quantum yield (Fv/Fm) was highest for the NE condition. Waterlogging resulted in root rot and the loss of fine roots. Root rot after waterlogging was minimal under the NM condition. After waterlogging, root length and root weight were highest under the NM condition. The amino acid and sucrose content were also highest under the NM condition, before and after waterlogging. The saponin content was dependent on the nutrient levels, but was barely affected by waterlogging.
Conclusions: The findings of this study suggest that soil nutrient management as a standard condition during standard ginseng cultivation contributes to minimizing waterlogging stress.
