|Title:||Are there buds in the roots of Aspidosperma spp. (Apocynaceae)? A comparative morphoanatomical study of underground organs|
|Abstract:||Resprouting is an important strategy for plant persistence through time. This strategy is considered a functional trait that allows plants to recover from disturbances such as fire, drought and mechanical injuries. Despite advancements on the ecology of resprouting from underground organs, few studies aimed at elucidating the anatomical nature of these organs, which is key for the proper identification of the nature of these organs. Literature reports and field observations of Aspidosperma spp. with aggregate distribution and individuals physically connected via underground organs indicated that resprouting may occur in species of the genus. Aspidosperma Mart. & Zucc. representatives are trees in the Apocynaceae family, widely distributed in the Neotropics. In this study, we investigated the anatomy of the underground organs of four Aspidosperma spp. aiming at elucidating their anatomical nature. In addition, we monitored for bud formation on the underground organs of the selected species following collections and described the mode of origin and bud development of Aspidosperma cylindrocarpon. Our findings revealed the root nature of bud bearing underground organs of Aspidosperma, which indicates a potential for vegetative propagation via bud-bearing roots in species of the genus, an important trait in the regeneration of plant communities|
