摘要
胡先和郑万钧在20世纪40年代对水杉新种进行研究的同时,采集了种子寄给国内外树木园、植物园和试验林场进行引种研究。其中1948年春汪振儒在得到水杉后首先对水杉种苗进行了系统研究,并在1949年1月正式发表了《Observations on seed germination and seedling development of Metasequoia glyptostroboides Hu & Cheng》(《水杉种子及幼苗发育观察》)一文。由于文章发表的时间正值北平解放,该刊发行较少,并为英文所写,解放后也没有被人引用而被遗忘。2002年,笔者开始对我国重要保护植物——水杉造林技术进行系统研究,找到此文并引用,同时也找到了在北京最早引种栽植的水杉,确认北京为世界上最早成功引种水杉的地点之一。笔者还对上文的作者进行了多次访问,并进行了有关文献的查阅和实地调查,上文不但是第一篇有关水杉种苗的研究论文,而且是在中华人民共和国成立之前较早采用林木种子、苗木质量指标(净度、千粒重、发芽率、发芽势和苗高、地径等)系统研究林木种苗的论文之一,调查还澄清了水杉在中国以及北京早期引种的一些误传。
While making researches on new species of Metasequoia (Metasequoia glyptostroboides Hu & Cheng) in 1940s, Hu H H(胡先骕) and Cheng W C(郑万钧) posted the seeds to arboretums, botanical gardens and forest-experimental-farms at home and abroad. Wang Y C (汪振儒 ) published the article of Observations on Seed Germination and Seedling Development of Metasequoia glyptostroboides Hu & Cheng in Jan, 1949. In 2002, the authors of this paper found that article and cited it when studying the Metasequoia silviculture. Meanwhile, the authors discovered the earliest Metasequoia trees planted in Beijing and thus proved Beijing to be one of the first places where adventitious Metasequoia was successfully planted. Also, the authors interviewed the writers of that article several times, referred to relative documents and made on-thespot investigations. It is observed that the article was not only the first treatise on Metasequoia seedlings but also one of the treatises published before 1949 that researched on tree seedlings after examining tree seedseedling quality index, i.e., seed purity, thousand-seed weight, germination rate, germinating capacity, seedling height and caliper (basal diameter) etc. Misinformation on introduction of Metasequoia planting in Beijing and other places of China is cleared of after the investigations.
