Abstract:
Akebia trifoliate has been reported to have many pharmacological activities and the roots, petioles and seeds are used to different symptoms. However, the structure and anatomy of its seeds was almost not reported until now. In the present study, we investigated the morphological characters of the fruit and seed, and the anatomical characters of the testa, micropyle, embryo and endosperm, which could provide evidences for the study on classification, identification and application of A. trifoliate. Our results showed that the testa of A. trifoliate consisted of an epidermic cell layer, the sclerenchyma cells layer, the parenchyma cells layer and an innermost pigment layer. At the micropylar region, the outermost epidermal cells were specialized the white caruncle-like structure and the testa included a lot of lignified tissues. Endosperm comprises two layer cells. Outermost yellowish-brown layer cells contains lots of fat droplets, and innermost white layer cells contains lots of aleurone grains and crystalloids.
