Factors that affect rooting of cutting

Oxygen  supply

The root forming process requires ample supply of oxygen.

Light  Intensity

Soft  wood  cuttings and  herbaceous  cuttings used more light  for  synthesis  of  carbohydrates while  for  hard  wood cuttings  enough  carbohydrates  darkness  encourage rooting.

Tempurature

Cool to warm temperatures around the roots promote rooting because they reduce transpiration rate.

Relative  humidity

High relative humidity prevents desiccation and encourages rooting.

Leaf area

Some cuttings require leaves to root while others don’t.

Chemical  Treatment

Rooting hormones applied at the basal end of the cutting quicken the rooting process.

Common rooting hormones includes;

IAA (Indole Acetic Acid)

IBA (Indole  Bytric  Acid)

NAA (Naphthalene Acetic Acid)
