Does oxygen affect ageing mechanisms of Pinus densiflora seeds? A matter of cytoplasmic physical state.
During desiccation, the cytoplasm of orthodox seeds solidifies into an intracellular glass with highly restricted diffusion and molecular mobility. Temperature and water content govern seed ageing rates, while oxygen (O2) can promote deteriorative reactions. However, whether the cytoplasmic physical state affects involvement of O2 in seed ageing remains unresolved. We... -

A synopsis of Neotropical Dichapetalaceae.
The Neotropical Dichapetalaceae was last monographed by Prance (1972). Since then twenty-nine new species have been described and the known geographic distribution of many species has been much extended. The 1972 treatment is updated here with summary descriptions of all Neotropical species and keys for their identification. New information on...Range extensions, Dichapetalum, Conservation, Stephanopodium, Tapura, and Lectotypification
