The study analyzed calcium (Ca) status in 54 plant species from salinized habitats in Tianjin, focusing on Ca crystals and components.
Most species (38/54) exhibited Ca crystals, primarily drusy and prismatic Ca oxalate, with only one species showing Ca carbonate crystals.
The findings indicated that deciduous arbors and shrubs had higher Ca oxalate crystal concentrations, which helps them tolerate salt stress, while herbs displayed higher water-soluble Ca and no Ca oxalate crystals.
