<P> Adventitious buds develop from places other than a shoot apical meristem, which occurs at the tip of a stem, or on a shoot node, at the leaf axil, the bud being left there during the primary growth . They may develop on roots or leaves, or on shoots as a new growth . Shoot apical meristems produce one or more axillary or lateral buds at each node . When stems produce considerable secondary growth, the axillary buds may be destroyed . Adventitious buds may then develop on stems with secondary growth . </P> <P> Adventitious buds are often formed after the stem is wounded or pruned . The adventitious buds help to replace lost branches . Adventitious buds and shoots also may develop on mature tree trunks when a shaded trunk is exposed to bright sunlight because surrounding trees are cut down . Redwood (Sequoia sempervirens) trees often develop many adventitious buds on their lower trunks . If the main trunk dies, a new one often sprouts from one of the adventitious buds . Small pieces of redwood trunk are sold as souvenirs termed redwood burls . They are placed in a pan of water, and the adventitious buds sprout to form shoots . </P> <P> Some plants normally develop adventitious buds on their roots, which can extend quite a distance from the plant . Shoots that develop from adventitious buds on roots are termed suckers . They are a type of natural vegetative reproduction in many species, e.g. many grasses, quaking aspen and Canada thistle . The Pando quaking aspen grew from one trunk to 47,000 trunks via adventitious bud formation on a single root system . </P> <P> Some leaves develop adventitious buds, which then form adventitious roots, as part of vegetative reproduction; e.g. piggyback plant (Tolmiea menziesii) and mother - of - thousands (Kalanchoe daigremontiana). The adventitious plantlets then drop off the parent plant and develop as separate clones of the parent . </P>
