Profile of water uptake in winterfat during seed germination

摘要：

Aquaporins are enriched in zones of fast cell growth, expansion and vacuolization ( Ludevid et al., 1992;Schaffner, 1998).These observations suggest that aquaporins are involved in cell elongation and growth, osmotic regulation and resistance to drought and salinity stress ( reviewed in Schaffner, 1998 ; Johansson et al., 2000).We examined : (1) the role of aquaporins in seed water relations during seed imbibition and early seedling growth of winterfat at low temperatures ; and (2) water distribution and biophysical status within a germinating seed.
