“…This implies that the arrested growth of the rhizome that followed the cutting of tip parts from a big plant system as reported by TIDMARSH (1939), was probably caused by an assimilate shortage in the rhizome tip. Import of assimilates into tip parts of a plant with a growth habit similar to that of the sand sedge is also reported from 14C distribution studies in Cynodon dactylon (FORDE 1966a) and in Ranunculus repens (GINZO & LoVELL 1973).…”

“…This study on growth and dry matter distribution in sand sedge plants forms part of an investigation on the physiological properties that permit the far creeping growth of these rhizomatous plants. In studies on plants that grow with rhizomes or stolons it is important to find out to what extent the shoots are dependent on each other (TIDMARSH 1939, GINZO & LoVELL 1973, ALLESSIO & TIESZEN 1975.…”

The growth and the dry matter distribution of sand sedge plants were followed in time by means of an indirect estimation method. This method enabled us to calculate the time courses of both the growth of the whole plant, and the growth of the individual shoots from measure: ments of the shoot length, the number ofleaves and the length and width of the leaflaminae only.The growth rate of each individual shoot decreases with time. In the primary shoots 1-7 the amounts of dry weight added during the experiment were equal to each other, indicating a higher growth rate for the younger shoots. A comparison of dry weight production and increase in dry weight of shoots gave the amount of dry matter import or export by those shoots. The dry matter production in the tip part of the rhizome (two shoots, a shoot bud, the rhizome parts and the roots attached to them) proved to be far too small to maintain the growth of the non-assimilating tissue in this part. There must be a considerable export from the older plant part towards the rhizome tip region. It should be mentioned that the results presented here are similar to those obtained from 14C studies. Because of its simplicity the method we used would be very suitable for use in field studies.

“…In contrast, less than 20% of the labelled carbohydrate was found in older segments of Carex bigelowii (Jonsdottir and Callaghan 1988) and less than 10% in Clintonia borealis (Ashmun et al 1982), two species with clonal architectures similar to mayapple. Ranuculus repens, a species with a more complicated clonal morphology, also exported less than 10% of labelled assimilate to older portions of a labelled stolon (Ginzo and Lovell 1973).…”

“…Because genetic individuals in such species are not stationary, they experience spatial variation in environmental characteristics. These features of clonal plant biology have led ecologists to describe clonal growth as a movement process (Bell 1984, Sutherland and Stillman 1988, Cain 1990, Callaghan et al 1990, Klimes 1992 and to investigate empirically the morphological response of plants to spatial variation in biotic and abiotic components of their environment (McIntyre 1967, Ginzo and Lovell 1973, Turkington and Harper 1979, Penalosa 1983, Salzman 1985, Grime et al 1986, Slade and Hutchings 1987a, b, Kelly 1990, see also the recent review by Hutchings and de Kroon 1994). Some clonal plant species decrease rhizome or stolon internode lengths and/or increase the frequency of branching in favorable environments (Ashmun and Pitelka 1984, Schmid 1986, Mitchell and Woodward 1988, de Kroon and Knops 1990, Alpert 1991, and references cited in Table 1 in Sutherland and Stillman 1988).…”

Some clonal plant species decrease rhizome or stolon internode lengths and/or increase the frequency of branching when they grow in favorable environments. This foraging response is thought to be beneficial since it should allow ramets to concentrate in areas of favorable habitat. However, there have been few critical tests of the effectiveness with which ramets are placed in favorable habitat as a result of the foraging response. In this paper, I use empirically calibrated stochastic simulation and diffusion models to compare the growth of clones in favorable and unfavorable habitat. I ask whether observed changes in rhizome lengths and clonal branching patterns are likely to decrease significantly the distance clones move, and thus, to enable mets to remain for longer periods of time in favorable habitat. For the empirical data used in this study, results from the models indicate that the effectiveness of the foraging response is likely to be variable. In some cases, such as results from models based on the response of Glechoma hederacea to nutrients, there is no significant difference in the distance clones move in favorable and unfavorable habitat. Thus, even through rhizome lengths may be significantly shorter in favorable patches, this does not guarantee that clones disperse significantly less far and thereby remain longer in favorable habitat. The effectiveness of the foraging response depends strongly on the distribution of clonal growth angles, the pattern of clonal branching, and the variance in rhizome or stolon internode length. These results, particularly the importance of growth angles and the relatively limited effectiveness of the foraging response, differ from those in previously published models of foraging in clonal plant species. I conclude with a discussion of reasons that may underlie these differences.
