S., Growth and reproductive characteristics of the columnar cactus Stenocereus queretaroensis and their relationships with environmental factors and colonization by arbuscular mycorrhizae, Tree Physiology, 2002, 22(9):667-674, doi: 10.1093/treephys/22.9.667
The study compares seasonal growth, reproduction and arbuscular mycorrhizal root colonization in three natural Stenocereus queretaroensis populations in western Mexico. It also examines tissue phosphorus, fruit traits and germination. Field observations show that relationships vary among populations.
