Variation in functional traits, growth relationships, and resource allocation among annual twig of dove tree along with latitudes

<p><span>Dove tree (Davidia involucrata Baill.), a monotypic rare species in China and a famous ornamental plant in the world, was employed as a model species in our study. The  morphological and biomass traits  of annul D. involucrata twigs were investigated in three latitude regions (32°19′ N, 30°08′ and 27°55′) in the Sichuan, Southwest China. </span></p>
