The stem of higher plant generally shows the negative gravitropism in the vegetative growth. On the other hand in the reproductive growth, there are some plants, such as the peduncle of Papaver rhoeas (poppy) and Eichhornia crassipes (water hyacinth) and the gynophore of peanut (Arachis hypogaea) in which the downward growth was shown toward gravity direction. Such interesting phenomenon, positive gravitropism of Eichhornia crassipes is considered to be specific in the reproductive growth. The downward growth of the stem in the reproductive growth of Eichhornia crassipes is discussed from a viewpoint of the gravitropic response.
