Transport of resources among connected ramets can increase the growth of clonal plants when ramets are located in microsites with contrasting light, water, or total soil nutrient availability. To test whether this is also true for soil nitrogen availability alone, two greenhouse experiments were conducted using the stoloniferous herb Fragaria chiloensis (beach strawberry). First, pairs of ramets were prepared in which the two ramets were connected by a stolen but rooted in separate pots. Ramets in a pair were: (1) severed from each other and given contrasting levels of soil nitrogen (high vs. low); (2) left connected and given contrasting levels of soil nitrogen; or (3) left connected and given a uniform level of soil nitrogen (both high or both low). Second, single ramets were given the high, the low, or one of three intermediate levels of soil nitrogen. Maintaining the vascular connection between ramets given contrasting levels of the soil nitrogen resulted in a greater production of new stolons and new ramets by the ramet given low nitrogen level, and in slightly greater leaf growth of the ramet given the low nitrogen level if it was also younger than the connected ramet. However, a ramet given high soil nitrogen grew much more than a ramet given low soil nitrogen, even when connected. Maintaining the vascular connection between ramets given a uniform level of soil nitrogen had no significant effect on growth. Single ramets given a higher soil nitrogen had greater total and component masses, more stolons and new ramets, higher nitrogen concentrations, higher specific leaf area, and a higher proportional mass of leaves and of stolons and new ramets. Experiments suggested that: (1) transport of nitrogen among ramets can increase growth in F. chiloensis, but to a limited extent; (2) transport of nitrogen through a stolon may be either acropetal or basipetal but tends to promote the growth of younger ramets; (3) higher soil nitrogen availability alters plant architecture by increasing allocation to leaves and to new stolons and ramets; and (4) physiological integration among ramets modifies colonal architecture because nitrogen acquire by roots promotes growth of both a rooted ramet and its new ramets, whereas nitrogen acquired from another ramet promotes the growth of new ramets almost exclusively.
