摘要

【摘要】新石海(Neolitsea acuminatissima)新鲜种子在30/20℃光照条件下(每天光照12 h)萌发缓慢，需要> 20周才能完全萌发。种子在4℃冷分层处理9个月或1年，不仅保持了原有的活力，而且发芽率显著提高。新鲜种子具有发育完全的胚和透水的种皮和内果皮，在温暖的温度下发芽需要> 4周。因此，我们的结论是

Seed Dormancy and Germination in Neolitsea acuminatissima (Lauraceae)

【Summary】 Fresh seeds of Neolitsea acuminatissima germinated slowly at 30/20℃ in light (with a 12-h daily photoperiod) and required > 20 wk to complete germination. Seeds cold-stratified at 4℃ for 9 mo or for 1 yr not only retained their original viability, but the germination rate significantly increased. Fresh seeds have a fully-developed embryo and a water-permeable seed coat and endocarp, and they require > 4 wk to germinate in a warm temperature regime. Thus, we concluded that

期刊介绍： The Taiwan Journal of Forest Science is an academic publication that welcomes contributions from around the world. The journal covers all aspects of forest research, both basic and applied, including Forest Biology and Ecology (tree breeding, silviculture, soils, etc.), Forest Management (watershed management, forest pests and diseases, forest fire, wildlife, recreation, etc.), Biotechnology, and Wood Science. Manuscripts acceptable to the journal include (1) research papers, (2) research notes, (3) review articles, and (4) monographs. A research note differs from a research paper in its scope which is less-comprehensive, yet it contains important information. In other words, a research note offers an innovative perspective or new discovery which is worthy of early disclosure.
