Final answer:
To induce rooting in plant cuttings, factors such as rooting hormones, layering, and environmental conditions can be manipulated to promote root growth.
Step-by-step explanation:
To manipulate the factors that affect rooting and induce the rooting of a cutting, several methods can be employed. One method is the use of rooting hormones, such as auxins, which promote the growth of adventitious roots on cuttings. Applying synthetic auxins to plant tissues can help stimulate root development. Another method is layering, where a portion of the stem is bent and covered with soil, encouraging root growth. Additionally, providing the appropriate environmental conditions, such as moisture and temperature, can also facilitate the rooting process. By using these techniques, it is possible to manipulate the factors that affect rooting and successfully induce root growth in plant cuttings.
