This invention relates to growth media for capturing and sustaining the growth of conifer embryogenic tissue and conifer embryos. Using media of the invention allows good growth of embryogenic tissue and conifer embryos which can subsequently be germinated to obtain plants. With these media there is no need to use plant regulator/hormones such as auxins and/or cytokinins for embryogenic tissue cature and maintenance.

Growth medium

This invention is directed to a method for maturing plant material, such as cotyledonary stage embryos, on a medium which includes the step of placing a filter over a vessel containing the plant material and the medium, the filter being water vapor permeable and impermeable to micro-organisms.
