Gentianella caucasea, G. germanica (with hemitropous ovules) and Swertia iberica (with ana-campilotropous ovule) are characterized by proliferated antipodals and rapid seed development (less than 25 days). Proliferated antipodals accelerate embryogenesis by substituting for the function of the endosperm in the early stages and promote rapid seed development. The structural differences of ovule and embryo sac may determine duration of the life cycle, which may stipulate for development of a specific adaptation to the severe environmental conditions due to the shortening of a life cycle and origin of annual ephemers well adapted to the cold and arid climate of alpine environment. 2004-01-01 published Bulletin of the Georgian National Academy of Sciences 170 1 Georgian National Academy of Sciences 125-129 http://scholar.google.com/citations?view_op=view_citation&hl=en&user=SLNYbL0AAAAJ&cstart=40&citation_for_view=SLNYbL0AAAAJ:bEWYMUwI8FkC TRUE 0132 - 1447 http://www.science.org.ge/english.html https://www.researchgate.net/publication/256421501_Relationships_between_structure_of_the_reproductive_organs_and_the_life_cycle_in_the_family_Gentianaceae?ev=prf_pub
