Root cytokinins, acid phosphatase and nodule activity in drought-stressed mycorrhizal or nitrogen-fixing alfalfa plants

Abstract

The objective of this research was to study the root and nodule responses to drought of mycorrhizal or nitrogen-fixing alfalfa plants in relation to root cytokinin levels. Double symbiotic plants showed significantly higher root and nodule activities during drought that may be related to smaller decreases in cytokinin content of mycorrhizal plants.
