“…These concentrations are also constant and independent of the external availability level in Senecio (Fenner 1986), however they can be increased by fertilizer application in a number of other species (e.g. Iwata & Eguchi 1958;Lipsett 1964;Austin 1966a,b;Schweizer & Ries 1969;Williams & Bell 1981). In the studies cited it would be interesting to know whether the reproductive biomass allocation was limited by one of the applied nutrients and by which.…”

The frequency of annuals, monocarpic perennials and polycarpic perennials among the dicotyledonous, herbaceous representatives of the European plant families are compared and related to various characteristics of plant architecture. It is suggested that the evolution of life-history may be governed by plant architecture. A comparison between annual and biennial Centaurium species suggests that the selective advantage of bienniality could relate to the production of a large stem within a short period. The typical architecture of a monocarpic perennial does not automatically imply an allometric relation between seed production and plant size. Size-dependent seed allocation, when present, is due to disproportionality between the plant's size and the amount of resources available for reproductive allocation, and not to the size constraints imposed by the plant's architecture. The evolution of monocar pic perenniality is therefore not a simple allometric step. Interpopulation differences in seed allocation may arise from differences in the nature or the availability of that particular resource that limits the reproductive allocation of biomass, and do not necessarily reflect differences in partitioning strategies.

The objective of this study was to determine whether infection of Avena fatua L. plants by the mycorrhizal fungus Glomus intraradices Schenck & Smith could influence the vigor of the offspring generation. Two experiments demonstrated that mycorrhizal infection of the maternal generation had slight but persistent positive effects on offspring leaf expansion in the early stages of growth. In two other experiments, mycorrhizal infection of mother plants had several long lasting effects on their offspring. Offspring produced by mycorrhizal mother plants had greater leaf areas, shoot and root nutrient contents and root:shoot ratios compared to those produced by non-mycorrhizal mother plants. Moreover, mycorrhizal infection of mother plants significantly reduced the weight of individual seeds produced by offspring plants while it increased the P concentrations of the seeds and the number of seeds per spikelet produced by offspring plants. The effects of mycorrhizal infections of maternal plants on the vigor and performance of offspring plants were associated with higher seed phosphorus contents but generally lighter seeds. The results suggest that mycorrhizal infection may influence plant fitness by increasing offspring vigor and offspring reproductive success in addition to previously reported increases in maternal fecundity.
