Neoregelia 'Flandria'and N. 'Van Durme'are ornamental cultivars of Bromelia.Propagation by seeds is not viable and prunes constitutes the only way to propagateavoiding alterations. In this article the developmental floral pattern of 72 Bromeliastreated with ANA 190 ppm (T1), Ethrel: ANA + ETHREL,(T2) y ETHREL, (T3) anddivided into two age groups: E1 y E2 are shown. The treatments studied generated moreelongated plants and six new patterns. Using the Markov chain methodology theprobability to evolve to any pattern and the percentage of each were studied.
