Medicago minimaandErodium cicutariumare two naturalized annual species in extensive semi-arid, temperate rangelands of central Argentina. A field study was conducted during 1989 and 1990 to evaluate the effects of different levels of soil water availability on above- and below-ground dry weight production and partitioning in these species. Dry weight production byM. minimawas more sensitive to water stress than that byE. cicutarium. Although the response was more marked inM. minima, both species allocated a larger proportion of total plant dry weight to fruits under water stress than under irrigated conditions during early spring. Percentage allocation of total plant dry weight into reproductive organs in both species, and stems and peduncles inE. cicutarium, was correlated with total dry weight of these organs; this might indicate a correlation between sink size and strength. Persistence of both species in the local flora appears to be associated with their capacity to colonize open, degraded areas and grow in association with native perennial grasses, as well as to tolerate severe drought periods.Copyright 1998 Annals of Botany Company
