Characterization of the photosynthetic pathway of some tropical food yams (Dioscorea spp.) using leaf natural 13C abundance uri icon

abstract

  • A total of 23 genotypes belonging to seven tropical food yams and two wild relative species of different origin and coming from two sampling ecological zones (the Republic of Benin in Africa and Guadeloupe in the Caribbean) was analysed for their C-13 content. The delta C-13 values for all yam samples (from -25.39 and -30.07 parts per thousand) indicated that all species had a C-3 photosynthetic type.
