Abstract
The fruits and seeds of Hedysarum zundukii collected in two locations of its growth: at cape Zunduk and cape Khuzhir of West coast of Lake Baikal in 2007-2009 were studied. It was established that only 19-39 % of collected bean segments contained mature seeds depending on the year of collection and the place of its growing. Other segments were empty or contained damaged and immature seeds. It was supposed that beans and seed damage was caused by insects. Mature seeds needed scarification for germination, and germination was near to 55 %. It was shown for the first time that seed damage and delay of their maturation may be a significant limiting factor for the preservation of Hedysarum zundukii depending on the place of its growing.
