Catechin, A Novel Root Exudate Of Centaurea Stoebe, Exhibits Pleiotropic Effects On The Soil Microbial Community And Individual Soil Isolates, And Undergoes Chemical Changes With Numerous Abiotic Factors From Soil, Jarrod Leroy Pollock
Graduate Student Theses, Dissertations, & Professional Papers
Allelopathy has been studied for (±)-catechin, a root exudate of spotted knapweed, as a plausible mechanism that facilitates knapweed invasion in North America. Phytotoxic effects are observed in invaded fields as well as greenhouse experiments when employing catechin or growing spotted knapweed, demonstrating similar effects on native plant species. However, many studies ignore the impact of catechin on microbial populations in soil. Understanding the impact of catechin on microbial processes will greatly aid our understanding of how spotted knapweed invasion can alter soil chemistry and biological processes. Chapter 2 will address the impact of soil and media parameters on catechin …
