Horticulture Propagation Quiz

Propagation is the process of producing new plants. Many horticultural crops are propagated through seeds because it is quick and economical. A good growing medium for seeds must drain well, hold moisture, and be sterile. Seeds are composed of a seed coat, endosperm, and embryonic plant. Producing plants from seed is a type of sexual propagation. Asexual plant propagation is the reproduction of plants through vegetative structures like stem cuttings rather than seeds, and is necessary to reproduce plants that do not produce viable seeds or to maintain their desirable characteristics.
