Reports summarize forestry study results from S. Silim and co-researchers.

According to recent research published in the journal Trees - Structure and Function, "The dynamic responses of stomatal conductance (g(s)) net photosynthesis (A) and leaf water potential (Psi(leaf)) to a progressive drought were examined in nine poplar clones (Populus spp.) with contrasting drought tolerance from the Canadian Prairies, a region prone to frequent droughts. Plants were grown in a greenhouse and either well-watered or drought preconditioned (5-6 cycles of drought) for 8 weeks."

"At the end of the last cycle, plants were watered to saturation then progressively dried-down (-1.25 MPa Psi(soil)) during which A, gs and Psi(leaf) were measured. Drought …
