Dormancy Breaking Of Acer and Fraxinus Seeds - A Brief Review

Abstract

This paper describes the most important methods of seed dormancy breaking based on existing literature for Acer and Fraxinus genera. Such methods are important for shortening seed germination. Seeds of many species from these two genera are released from dormant state when they are kept at relatively high humidity and generally low temperature; however more detailed investigations of the seed dormant state are needed, in order to recommend optimum pretreatments before sowing for each species.
