The effect of calcium to magnesium ratio on adenosine triphosphatases from wheat roots
The activities of ATPase isolated from 4 days old wheat roots grown on distilled water were found to be associated with the ratio of Ca : Mg ions added in different proportions to the incubation medium.

| Summary: | The activities of ATPase isolated from 4 days old wheat roots grown on distilled water were found to be associated with the ratio of Ca : Mg ions added in different proportions to the incubation medium. This relationship was stated in the crude cell wall free homogenate (fraction I) as well as subcellular fraction II and fraction III under investigations. It is stated moreover that activity of ATPases extracted from wheat roots grown on deficient nutrient solution with different Ca : Mg ratio is dependend on exogenic ratio of these cations. These results support the concept that activity of plant ATPases depends not only .on mineral nutrition and concentrations of Ca2+ and Mg2+ ions but also on the Ca : Mg ratio in soil or in nutrient solution and in separate subcellular fractions of plant cells. |
