摘  要:
白桂木是国家珍稀濒危植物(三级保护),通过人工育苗研究,打破白桂木种子休眠,创造条件提高种子发芽率,大量培育种苗,稳定和壮大种群数量,保护和恢复白桂木资源。通过无菌催芽、激素催芽等研究,白桂木种子沙床催芽发芽率达95%以上,入袋培育成活率达90%以上,掌握了一套白桂木种子育苗的技术。

摘  要:
Artocarpus hypargyreus belongs to state rare and endangered plants(third class protection).Artificial breeding was studied.Through breaking seed dormancy,and creating conditions to improve seed germination,a large number of seedlings were bred.The Artocarpus hypargyreus population amount was stabilized and expanded.Through study on the asepsis and hormone accelerating germination,the seed germination rate of sand bed reached more than 95%,and the survival rate with nutritional bag achieved more than 90%.In the end a set of Artocarpus hypargyreus breeding technique was mastered.
