Title
Role of Calcium in Aluminum Toxicity on Content of Pigments and Pigment‐Protein Complexes of Soybean
Dragica Milivojević; D. Stojanović Journal of Plant Nutrition 2003. doi:10.1081/pln-120017140
Other claims from this paper (4)
- Intervention effect Soybean leaf calcium content decreased with increasing solution aluminum concentrations and decreasing Ca:Al ratio.
- Intervention effect Without solution calcium, the decrease in soybean pigment parameters was more pronounced.
- Intervention effect Soybean chlorophyll-protein complexes were altered in photosystem 2, especially under aluminum stress and calcium deficiency.
- Intervention effect Aluminum-treated soybean chlorophyll-protein complexes were not significantly decreased when calcium concentrations were 0.05 to 0.1 M.
