A better understanding of embryo development would provide insights into seed   quality and subsequent germination events in the interspecific hybridization   of Cymbidium faberi ‘Jiepeimei’ × C. sinense ‘Qijianheimo’. At the mature   stage, 26.1% of the ovules were abnormal. Most of the hybrid embryos could   develop normally. Abortions mainly occurred at the zygote (9.5%) and   2-4-celled embryo (15.1%) stages. No germination was observed at 90 and 105   days after pollination (DAP), when the embryo was at the early globular   stage, with abundant organelles but no storage materials. During 110-130 DAP,   the globular embryo was formed and the starch grains began to accumulate in   plastids. The hybrid seeds collected at 120 DAP showed initiation of   germination. Germination significantly increased at 135 DAP and was maximal   at 150 DAP, during which period the hybrid embryos developed into the late   globular stage. The storage materials, i.e. lipid and protein bodies, began   to accumulate and the filamentary structures derived from suspensor cells   still persisted. After the seeds matured (160 DAP), the germination   percentage declined sharply. Safranin staining revealed that the outer seed   coat was totally cuticularized and the inner seed coat appeared as a cuticle   layer enclosing the embryo proper tightly, which may be the main factor   inhibiting the subsequent germination of hybrid seeds. In conclusion, 150 DAP   should be the opportune time for the in vitro germination of C. faberi   ‘Jiepeimei’ × C. sinense ‘Qijianheimo’ hybrid seeds
