Ecophysiological characteristics of turions of aquatic plants: A review

Popis výsledku v původním jazyce

Turions or winter/overwintering buds are vegetative, dormant storage organs formed by perennial aquatic plants. They are formed in subtropical to polar zones in response to unfavourable ecological conditions, usually at the beginning of autumn. In this way, fragile shoots of aquatic plants avoid freezing and damage. Turions are formed in at least 14 genera of aquatic vascular plants from nine plant families, mainly in submerged (or amphibious) and free-floating species. Turions are propagules formed by extreme condensation of apical stems (internodes) with modified attached leaves or scales which are dissimilar to summer leaves, they germinate and sprout after they separate from the mother plant. As opposed to pale subterranean rhizome apices, turions contain chlorophyll and sprouting turions are able to photosynthesize, which gives them an ecological advantage. Here I review various aspects and particulars of turion biology – structure, ecological significance, costs and benefits, turion formation, dormancy, germination, sprouting, metabolism and frost tolerance – from an ecophysiological point of view with an emphasis on ecological and biochemical developmental signals of turion formation and germination or sprouting. All turion forming genera and species are included except Spirodela polyrhiza.
