Maintenance of water uptake and reduced water loss contribute to water stress tolerance of Spiraea alba Du Roi and Spiraea tomentosa L.

Stanton, K. M., & Mickelbart, M. V. (2014). Horticulture research, 1, 14033.



Plants that are able to tolerate drought conditions without wilting are more desirable as landscape plants,5 and neither species exhibited wilting during the gradual water stress event in this experiment. Growth was inhibited by water stress, but this would not detract from their landscape potential. While the experimental design employed allowed for a slow dry-down, in a typical landscape loam soil, the decrease in water availability would likely be even slower, perhaps allowing for greater potential to adapt to the reduced water availability.
