For cuttings used in propagation to grow root faster, rooting hormones are usually used.due to the fact that the plant root hormones have not been produced, the rooting hormones added facilities the growth of root till the plant root hormones are produced.this lead to strong root and faster growth of plants. Rooting hormones which has auxis present inside of it helps in cell length growth. Rooting hormones which also help increase auxin concentration in plants leads to faster and stronger plant growth.using when it is placed or applied into the cuttings, it will help produce root cell via(through) the replacing of stem cell in plant with undifferentiated cell ( that form the root cell)
