Do greenhouse experiments predict willow responses to long term flooding events in the field?

Flooding tolerance should be included as a trait in breeding programs in forested areas where extreme flooding events lasting several months can occur. In this context, it is difficult to carry out controlled, long-term flooding experiments with big trees due to the large number of specimens to scre...
