Age Mediated Effects On The Alternative Respiratory Pathway In Leaves Of Rhodiola Rosea And Ajuga Reptans, Natalia V. Pystina, Roman A. Danilov

Turkish Journal of Botany

The influence of aging processes on respiration and the ratio of respiratory pathways in the leaves of Rhodiola rosea L. and Ajuga reptans L. under natural conditions was investigated. Young leaves had a higher respiration rate and higher activity of the alternative respiratory pathway than did mature leaves. The capacity of the alternative respiratory pathway did not show significant differences between the young and mature leaves of R. rosea and increased in the mature leaves of A. reptans (from 60% up to 88%). This fact may be explained by the higher requirements of growing tissues for metabolites. In this case, …
