Variety traits

Drought tolerance — Berberis thunbergii

Berberis thunbergii DC.

Berberis thunbergii exhibits moderate drought tolerance, requiring regular watering only at a young age and during periods of severe drought. The plant is sensitive to waterlogging and requires well-drained soils for full adaptation.

In the reference 5 varieties crop Japanese barberry, where this is mentioned in the description.

Once established, mature specimens demonstrate the ability to adapt to varying moisture levels; however, prolonged water deficit negatively affects leaf turgor, growth intensity, and the overall winter hardiness of the shrub. Excessive moisture poses a greater risk to the crop than temporary drought due to the risk of root system damage.

Under field research conditions, a 5-point scale of visual damage is used to assess the species' drought tolerance, where the highest score is assigned to plants showing no signs of leaf margin scorching or premature leaf drop. In laboratory practice, tolerance is assessed through leaf water-holding capacity indices and water recovery coefficients.
