High Atmospheric CO₂ Concentration Mitigates Drought Effects on Acanthostyles buniifolius an Important Grassland Weed in South America.

ABSTRACT: The differential growth and yield response of plant species to rising carbon dioxide concentrations and climatic change may alter species diversity within biomes. The Pampa Biome in South America is an important grassland biome of agronomic and environmental importance. Acanthostyles buniifolius (Chirca) is one of the most important weeds in natural pasture areas widely distributed in southern South America and can adversely affect livestock production. The current study was designed to identify possible responses of Chirca to CO₂ concentration ([CO₂]) and drought that would indicate higher adaptation and potential proliferation within the Pampa Biome. Chirca plants were cultivated at two CO₂ concentrations (400 (a[CO₂]) and 700 (
