High temperatures disrupt water regulation behavior in Pinus radiata
By
Sharma, Kritika, Bourbia, Ibrahim, Pérez, Faustino Rubio, Brodribb, Timothy
Summary
This article examines how high temperatures affect the water regulation behavior of Pinus radiata (radiata pine). While this species has traditionally been characterized as strongly isohydric—meaning it closes its stomata to maintain stable leaf water potential—the research suggests that under high temperature conditions, this isohydric behavior is lost. The study investigates the physiological response of the tree to thermal stress, indicating a shift in water management strategy when temperatures rise.
