We evaluated the effect of global warming on Araucaria angustifolia (Bert.) O. Kuntze, a critically endangered native tree of Southern Brazil, by studying the effects of short‐term high temperature treatment on cell viability, respiration and DNA repair of embryogenic cells. Compared with control ce...
