Final answer:
Benzyladenine, a type of cytokinin, can induce the formation of adventitious shoots on leaf cuttings.
Step-by-step explanation:
Benzyladenine can be induced to form adventitious shoots on leaf cuttings. This plant hormone is a type of cytokinin, which is known to promote mitosis and stimulate differentiation of the meristem in shoots and roots. Hormones like indolebutyric acid (auxin) and gibberellic acid have different primary functions, such as promoting root growth and breaking seed dormancy, respectively. While these hormones might also play a role in shoot induction in some scenarios, benzyladenine is specifically known for its effectiveness in stimulating adventitious shoot formation.
