CO2 fertilizer effect on growth,
polyphenols, and endophytes
in two Baccharis species.

"The enhanced growth under elevated CO2 signifies what the authors describe as "an important achievement, especially when considering the typically slow growth pattern of the Cerrado plant species."

... they envision such growth will bring about "a denser savanna." And because polyphenols are known to enhance plant physiological and performance ...

,,, these findings together suggests both Baccharis species will remain important for use in bioremediation and medical applications.

According to Oki et al. (2020), Baccharis dracunculifolia and Baccharis platypoda are two key shrub species in tropical South America of considerable economic and biological importance.

In particular, the species thrive on soils contaminated with heavy metals, making them suitable for bioremediation.

And high leaf concentrations of diterpenes, triterpenes and flavonoids enhance the usability of these two shrubs in a broad array of medical and cosmetic applications.

... elevated CO2 stimulated plant height and leaf number by +15.4% and +16.1% in B. platypoda and +54.5% and +31.5% in B. dracunculifolia."
