Estudios preliminares sobre el efecto de dos brassinosteroides sintéticos sobre el crecimiento in vitro de yuca, ñame y piña

The effect of two brassinosteroids, (22R,23R)-2α,3α,22,23-tetrahydroxystigmastan-6-one (28-homoethylcastasterone) and (22R,23R)-3β-acetoxy-22,23-dihydroxystigmastan-6-one, was evaluated over micropropagation growth of three tropical plants commonly known as cassava (Manihot esculenta, Crantz, CM-668...

Darién cultivar) and pineapple (Ananas comosus L., Merrill, Cayena Lisa vatiety). Usually, these plants show a slight response to growth promoting factors and a low rate of development under in vitro micropropagation conditions. The number of stems, the number of roots and the height of the seedlings in cassava and yam, and bud sprout from pineapple crown were studied. Results suggest an improvement of micropropagation processes when using these brassinosteroids, although further studies should be carried out in order to obtain the best experimental conditions for their application.
