“…A low soil water content is conducive to the synthesis of saponins in the roots of P. notoginseng (Zheng et al, 2021; Xia et al, 2016). However, other studies have shown that a low soil water content can inhibit the accumulation of saponins in the roots of P. notoginseng , but promotes the accumulation of saponins in the leaves (Yang et al, 2023; Gao et al, 2019), which is similar to our results (Figure 3). In this study, drought stress severely inhibited the basic growth and development of P. notoginseng .…”

“…Influenced by the limited land resources and increasing demand, the model for P. notoginseng cultivated in the forest has been rapidly developed for high‐quality and safe production, providing a suitable growing environment with a high level of biodiversity (Yang et al, 2023; Wu et al, 2020). By 2020, the planting area of P. notoginseng cultivated in the forest in the Yunnan Province was approximately 1333 hm 2 (Yang et al, 2023; Yang et al, 2020). Appropriate irrigation improves plant immunity and promotes healthy growth by affecting nutrient utilization and modifying the physical and microbiome properties of the soil (Kresovi'c et al, 2016; Soothar et al, 2021).…”

“…Appropriate irrigation improves plant immunity and promotes healthy growth by affecting nutrient utilization and modifying the physical and microbiome properties of the soil (Kresovi'c et al, 2016; Soothar et al, 2021). We have previously reported that a quantitative irrigation of 80–85% field moisture capacity was conducive to maintaining the balance between yield, saponin content, and disease occurrence in P. notoginseng cultivated in the forest (Yang et al, 2023). In addition, our previous research results on planting P. notoginseng in plastic greenhouses showed that no matter what kind of soil, high soil water (75–90% field moisture capacity) content was conducive to the accumulation of biomass of P. notoginseng (Guo, 2019).…”

Drought is the most common abiotic stress that hinders plantgrowth. To clarify the changes in the growth and metabolism of Panax notoginseng following drought stress, here the effects of drought stress on the growth and metabolism of P. notoginseng are investigated using gas chromatography–mass spectrometry based on a widely targeted metabolomic approach. We conducted drought stress treatments (DS) and re‐watering treatments after drought stress (RW) with no drought stress as the control group. The results showed that DS treatment significantly inhibited biomass accumulation and root development of P. notoginseng. Single saponin Rg1 and total saponin in the roots were the highest in the control group, while the total saponins in the leaves were the highest in DS. A total of 120 metabolites were identified using metabolomics and they were classified into eight categories. The metabolites of P. notoginseng under DS were significantly different from the control and RW treatment. Caffeic acid was significantly enriched in all comparison groups, suggesting its important role in the drought resistance of P. notoginseng. Enrichment analysis of differential metabolites showed that the ATP‐binding cassette (ABC) transporters, the metabolic pathway of valine, leucine, and isoleucine were closely associated with the drought resistance of P. notoginseng. We also verified that significantly upregulated differential metabolites such as 5‐aminolevulinic acid (5‐ALA) and quinic acid can enhance the drought resistance of P. notoginseng through exogenous application.

Purpose The ecological cultivation of Panax notoginseng under a forest canopy relies on the coupling of the P. notoginseng growth environment and the forest ecosystem Methods In this study, six tree species, such as Platycladus orientalis (L.) Franco, were chosen to research the effects of species interactions on the growth, quality, and disease occurrence under intercropping with P. notoginseng, with single P. notoginseng serving as the control. Results Intercropping P. notoginseng with PO (Platycladus orientalis, a coniferous tree species) or with SW (Schima wallichii Choisy, a broad-leaved tree species) promoted the accumulation of P. notoginseng biomass, reduced the occurrence of root rot, improved the contents of nitrogen, phosphorus and potassium in P. notoginseng, and increased the saponin concentration. Then, 43 differentially abundant metabolites were screened in the P. notoginseng-tree intercropping system by soil metabolism analysis and compared with those in the monocropped system. Indole-3-carboxaldehyde showed a significant negative relationship with the occurrence of root rot disease and inhibited Fusarium oxysporum. In addition, 2-naphthalenesulfonic acid was significantly positively correlated with biomass and increased the dry weight in the underground part of P. notoginseng in the pot experiments. Conclusions Thus, the coniferous tree species PO and the broad-leaved tree species SW are potentially good neighbours of P. notoginseng, and soil metabolic changes may be important mechanisms for the growth and disease resistance benefits observed in the understorey of P. notoginseng.
