Sexual and asexual propagation of Baccharis dracunculifolia DC., a dioecious medicinal Brazilian shrub
نویسندگان
چکیده
Baccharis dracunculifolia DC. is a pioneer plant native from Brazil that has great importance due to its secondary metabolites (essential oil and Brazilian green propolis) potential in the recovery of degraded areas. The main goal this study was evaluate propagation techniques B. by sexual reproduction asexual male female stem cuttings. For reproduction, individuals natural population were periodically monitored for their reproductive development diaspores collected maximum dry mass accumulation determine physiological maturity. germination test performed testing four temperatures (20, 25, 30, 20–30°C), addition speed index (GSI) first count. vegetative propagation, cuttings (8 cm) treated with an indole butyric acid (IBA) solution at 0, 1,500, 3,000, 4,500, 6,000 mg L−1. evaluated mortality, survival, rooting, sprouting, leaf retention, callogenesis, number roots, average length roots (cm) after 120 days. maturity occurred 40 days anthesis, which best time collection field. 25 or 20–30°C should be used tests species. count identified sowing last 11 rooting very low. Sex did not influence parameters, but increasing IBA doses positively influenced negatively calluses formation.

Streptococcus mutans triggers dental caries establishment by two major factors: synthesis of organic acids, which demineralize dental enamel, and synthesis of glucans, which mediate the attachment of bacteria to the tooth surface. Propolis is a natural product that may prevent dental caries. Baccharis dracunculifolia DC (Asteraceae), a native plant from Brazil, is the most important botanical o...
