  Cold storage is a strategy mainly used for ornamental cuttings for the
purpose of prolonging production duration that provide the cuttings with the
best condition at the time of planting. The results have been obtained from
cold storage of carnations and chrysanthemums confirmed the fact that the
herbaceous cuttings could be stored for about two months at not lower than 0 C
and more than 4 C, with similar results of the cuttings directly planted
without storage. On the other hand, hardwood cuttings are stored at low
temperature in order to improve rooting ability via reducing rooting inhibitors
that occur in dormant cuttings which were taken during dormant seasons (late
fall or early winter). So, declining in rooting inhibitors has been observed in
the hardwood cuttings of deciduous trees and Vitis spp which were subjected to
low temperature for around 2-6 months. Consequently, rooting was improved in
these species. Also, cold storage of cuttings of some coniferous trees
increased rooting at a high rate. Other factors like cultivar and storage
method may interact with cold storage duration and temperature degree as well.
This review article outlines the information of the studies that have been
obtained as a result of cold storage of the cuttings of different species.
