To achieve the genetic improvement of plant species, a good knowledge of the reproductive biology of the species is required. The technical platform of microscopy, cytology and flower biology analysis aims at analyzing the reproductive system of plant species in order to facilitate crosses, recombination and the understanding of the mechanisms. With this platform, we study the structure and functions of cells and tissues of plant species, and do chromosomes counting. The platform focuses on the training of undergraduate and graduate students. We also provide assistance to scientists and development agents.
