Biomass and energy allocation in two orchids - Dactylorhiza majalis and D-fuchsii (Orchidaceae)

This paper describes and clarifies some of the trends in mass allocation in Dactylorhiza majalis and Dactylorhiza fuchsii to particular parts of the p lant, especially to reproductive organs, under- and above-ground structures , and vegetative and generative parts. Dactylorhiza majalis invests more bi omass into aboveground shoot and generative parts than Dactylorhiza fuchsii . The reproductive strategy of these two orchids mainly depends on the quan tity of generative parts such as faded flowers, capsules or seeds.
