Abstract
Many factors are important in the rooting of cuttings, however, juvenility appears to be one of the most important conditions.
The discovery of auxins greatly increased the spectrum of plants that could be rooted.
Although auxins can increase the rooting potential of a large number of plants, there still exist many difficult-to-root plants which respond very little to auxin treatments.
Many juvenile forms and easy-to-root plants contain substances, called rooting co-factors, which are capable of stimulating root initiation.
These rooting cofactors can be extracted by various solvents, centrifugation and steam distillation.
In addition to cofactors, root inhibiting substances have been shown to regulate the rooting process.
Although experimental evidence indicates that rooting cofactors have an important role in the root initiation process, evidence exists for the presence of non-mobile component of root initiation.
