On the other hand, conditions in the period following establishment, during establishment growth, affect vegetative regeneration and clonal growth of the plant in the future. Bud bank formation was studied in a root-sprouting clonal herb Epilobium angustifolium , a plant with root buds differing in size and number of leaf primordia, during establishment growth. We found out that the proportion of small buds was about 80 % and was not affected by nutrient availability and substrate heterogeneity; and plants produced more buds per root biomass under conditions of nutrient shortage in both homogeneous and heterogeneous substrates, but the effect was masked by lower root biomass.
