The influence of water availability and defoliation on extrafloral nectar secretion in quaking aspen ( Populus tremuloides )

In recent years, water stress has led to widespread growth declines and dieback of several North American tree species. In addition to its direct effects on tree physiology, water stress may compromise anti-herbivore defenses. We tested whether extrafloral (EF) sugar secretion rate in Populus tremuloides Michx. (quaking aspen) increases in response to… CONTINUE READING
