The prothallium produces both male and female sexual organs. When the female organs become fertilized by the male organs, small fern plants begin to grow. In some ferns it can take as long as six months for the first fronds (leaves) to appear after sexual fertilization.
For say 100,000 nematodes in a root system, the total nematode biomass is 20 g! Allowing for 50% production efficiency, total material extracted from the plant would be 40 g. So, the demand effect on the plant may be minimal unless plant is very stressed and resources are limited. An adult Heterodera schachtii consumes 11 nL/day of cell content (Muller et al, 1981). So, it would take 1,000,000 such females to remove 11 ml of cell content in a day.
