Effects of temporal heterogeneity in nutrient supply on intra- and inter-genet competition of a clonal herb

Nutrients are often released heterogeneously over time (e.g., in pulses) natural habitats. Different genotypes of the same plant species may vary their responses to temporal nutrient heterogeneity so that influence intraspecific interactions. To test effects on intra-genet (competition between ramets genotype) and inter-genet competition different genotypes), we conducted a greenhouse experiment with five clonal herb Hydrocotyle vulgaris. We grew one ramet (no competition), two genotype or pot supplied total amount nutrients either homogeneously heterogeneously. Results showed affected growth biomass allocation some genotypes, but had no impact those other H. These suggested were Temporal little effect vulgaris likely because did not differ heterogeneity. However, increased competitive ability higher productivity. conclude can interactions by altering competition, this further change population dynamics plant.
