Abstract

Turions of perennial aquatic carnivorous plants of the genera Aldrovanda and Utricularia are dormant, overwintering buds and are formed by extreme condensation of short, modified leaves in the shoot apex at the end of the growing season (Fig. 1) (Sculthorpe 1967; Bartley & Spence 1987; Adamec 1999). These tough organs represent also storage organs both for carbohydrates and some mineral nutrients (N, P; Winston & Gorham 1979a; Adamec 1999, 2003, 2010, 2011; PÅ‚achno et al. 2014) and their respiration rate is greatly reduced as compared to that of summer shoots (Adamec 2003, 2008a, 2011).

Keywords: Aldrovanda vesiculosa, Utricularia spp., winter buds, turion drying and freezing, turion sprouting
