Water entry in cercis siliquastrum leguminosae seeds



Water entry in cercis siliquastrum leguminosae seeds



Nordic Journal of Botany 4(5): 675-679



By use of scanning electron and light microscopy a study on the histological organization controlling water entry in the C. siliquastrum L. seeds was carried out. The intact mature dry seed of Cercis is impermeable. This property is prevalently due to a non-cellular layer situated at the inner border of the testa enclosing the endosperm. When this layer is damaged, water enters endosperm and embryo, increasing their volume, and stretching the testa. The testa copes with the increasing volume of the seed without rupturing and decreases in thickness. The shape of the hypodermal cells changes from almost circular in section to periclinally elongated, as an effect of the imbibition.
