During a six years' period the course of the life cycle was observed of five species of dune annuals at three different density levels. The studies have shown that: (1) the time of seedling emergence and the duration of the seedling phase depend primarily on the weather conditions; (2) after the seedling phase has been passed, an increase in density is accompanied by an acceleration of the developmental phases (until the flowering time) and shortening of the life cycle; (3) the shorter the growth cycle of a species the more marked is the effect of density on the phenological development of individuals.
