Seed storage behaviour of tropical members of the aquatic basal angiosperm genus Nymphaea L. (Nymphaeaceae).

ABSTRACT: Eighteen native species of Nymphaea (waterlilies) inhabit a range of freshwater wetlands in northern Australia, which are threatened by increased development and the potential impacts of climate change. To investigate conservation seed banking of these vulnerable species, we aimed to characterize their seed storage physiology by determining (i) seed desiccation tolerance and (ii) the effects of moisture content and storage temperature on seed germination and viability. Seeds of N. immutabilis, N. lukei, N. macrosperma and N. violacea (including multiple collections of three species) were placed in experimental storage at a range of temperatures (25°C, 5°C, -20°C and -190°C) following pre-equilibration at different RHs (15%, 30%, 50%, 70% or 95%). Seeds we
