Events Associated with Early Age-Related Decline in Adventitious Rooting Competence of Labill.

The development of adventitious roots is affected by several factors, including the age of the cutting donor plant, which negatively affects rooting capacity. quickly loses rooting capacity of cuttings as the donor plant ages, although the molecular and biochemical mechanisms behind this process are still unclear. To better understand the bases of rooting competence loss in , the time required for a significant decline in rhizogenic ability without exogenous auxin was determined in microcuttings derived from donor plants of different ages after sowing.
