“…The seeds of the studied species have a hard seed coat with a layer of macrosclereids (palisade-like cells with strongly lignified walls), typical for many wild Fabaceae species [24,25], and most part of them is characterized by high and moderate levels of hardseededness (Table 2). A physical dormancy often occurs as a means of adaptation to the different habitats with the severe climatic conditions, and such seeds are highly resistant to unfavorable environmental factors [26,27]. It is low permeability of hard seed coat that may play some role in the cryotolerance of these seeds [19,28].…”

Seed survival after storage in liquid nitrogen (–196°C) was examined in 12 wild medicinal legume species occurred Far East of Russia. Dry seeds of all species survived cryostorage without loss of viability. Initial germinability varied from 3 to 85%. The stimulatory effect of cryogenic temperature on germination, with or without subsequent chemical scarification, was observed in all species studied with deep physical dormancy or heterogeneous levels of hardseededness. Frozen seeds demonstrated higher germination percentages (the percentage of germinated seeds) and germination rates (time for first seed to germinate (T0) and time required (in days) to reach 50% of the final germination percentage (T50)) than the control ones. The anomalous seedlings were not observed after storage of seeds in liquid nitrogen. This study shows that cryostorage may be successfully applied for conservation of native species without detrimental effects on germination and growth.

“…Воздействие ультранизкой температуры с последующим размораживанием было аналогично воздействию серной кислоты и, по-видимому, также связано с повреждением семянной кожуры. Преодоление экзогенного типа покоя под действием сверхнизких температур отмечено ранее для видов Oxytropis (Kholina, Voronkova, 2012;Voronkova et al, 2008;Voronkova, Kholina, 2010) и других дикорастущих бобовых (Kholina, Voronkova, 2012;Pence, 1991;Perez-Garsia, 2008;Salomăo, 2002).…”

“…Цель настоящей работы -разработать подходы к сохранению генофонда ценного лекарственного растения O. lanata: выявить молекулярные маркеры для определения уровня генетического разнообразия, исследовать жизнеспособность и криоустойчивость семян O. lanata и оценить влияние глубокого замораживания семян на развитие растений на ранних этапах онтогенеза. Наша работа является продолжением собственных исследований по криоконсервации семян дикорастущих растений (Voronkova et al, 2008;Voronkova, Kholina, 2010).…”

“…Complete burial by ash kills small annual species (Smith, 1913;Gal an de Mera et al, 1999;Tsuyuzaki and Hase, 2005), but, if the tephra layer is not too deep, plants with buds localized near volcanic ash surface can recover more easily than annual species (Kent et al, 2001;Voronkova et al, 2008). Persistent seed banks can survive under tephra.…”
