Root competition among neighboring plants was studied by growing plants with their roots inside tubes of PVC pipes.Some tubes had holes of varying sizes,allowing their neighbors' roots to enter the tubes of a target plant.As the percentage of a target plant's tube open to neighbors' roots increased,

Question

Quizplus · Accepted Answer

When the percentage of a target plant's tube open to neighbors' roots increases, it allows neighboring plants to access more resources, such as water and nutrients, which leads to increased root biomass for the neighbor plants. However, the target plant has to compete for these resources and will have reduced biomass as a result. Therefore, the target plant biomass decreases and neighbor plant root biomass increases.
