When selecting materials for planting the following factors must be considered: Suitability to the ecological conditions The selected planting materials should be well adapted to the soil conditions, temperatures and amount of rainfall in the area. There are many varieties of maize, for example, which are suitable to different ecological conditions. Hybrid 622f or example

Temperature: for the cuttings to produce roots warm temperatures are required around the root zone while cool temperatures are important for the aerial part of the cuttings. For most species optimum day and light temperatures for rooting are 22 -27°c and 15-21° c respectively.  Relative humidity:Proper rooting of cuttings requires high humidity which lower the transpiration

These are plant parts which have the ability to produce roots, they grow and develop in to new plants.
