#morphophysiological dormancy

Seed dormancy of the first flowering plants

Dormancy mechanisms act to optimise the timing of seed germination for many seed plants. Fogliani et al. demonstrate that the New-Caledonian shrub Amborella trichopoda exhibits a type of morphophysiological dormancy in which the mechanical resistance of surrounding fruit tissues plays a key role in the initial physiological phase. Reconstructed chronological sequence of Amborella trichopoda seed…
