Abstract: | Summary On 27 September 1985, Hurricane Gloria intersected the Rhode Island land mass and disrupted normal autumnal element resorption in 20 ramets of a trembling aspen clone (Populus tremuloides). No mechanical injury to the plants was observed, but in contrast to undamaged aspens, the wind/salt-damaged aspens did not withdraw nitrogen (N) or phosphorus (P) from senescing leaves. There was actually 17% more N in abscising leaves than in presenescent, pre-hurricane leaves. |
