Desiccation tolerance of Zizania palustris seeds: temperature dependence, imbibitional damage, and role of 'dehydrin' proteins


Proceedings of the Fourth International Workshop on Seeds: basic and applied aspects of seed biology, Angers, France, 20-24 July, 1992 Volume 3: 851-856
Desiccation tolerance of Zizania palustris seeds: temperature dependence, imbibitional damage, and role of 'dehydrin' proteins
Previously thought to be intolerant of desiccation, seeds of North American wild rice (Zizania palustris var. interior) can survive dehydration to as low as 7% moisture content if dehydration occurs at temperatures >25 degrees C, and if imbibitional damage is avoided by slow rehydration at temperatures between 10 degrees and 25 degrees. Developing embryonic axes are germinable as much as 2 weeks prior to the acquisition of desiccation tolerance.
