We concentrate on two types of cutting: Pelargonium cuttings which are sensitive to extended darkness and those of different species (Dipladenia, Alamanda, Lantana, Heliotropium, Plecterntus and more ) which are sensitive to cold. In few of the species which are sensitive to cold we found that the ethylene receptor inhibitor, 1-MCP, reduces the damage as is seen in the picture of Alemnda cuttings.
