Brassinosteroids are natural compounds which have a strong biological activity and have been used as yield stimulators in agriculture. However, since 80´s decade endings of last century, searching of analogs of these compounds whose synthesis is more economic and that have a long lasting activity under field conditions has been working. In Cuba, some spirostanic analogs of brassinosteroids which have a biological activity like natural brassinosteroids and give very good results as crop yield and growth stimulators have been synthesized. In this paper, information about the activity of some of these analogs and its influence on germination, rooting, growth, yield and quality of some economically important crop is analyzed and discussed. Results about the use of these analogs as growth regulators in the plant micropropagation are, also, presented.
