水杉在1943年以前公认是绝迹的树种,1945年我国科学工作者在湖北省利川县水杉坝一带即现在的红星公社和青年公社等地发现该树种以后,通过鉴定证实水杉并未绝迹,所以有活化石之称.自此以后以种子和插条繁殖传播国内外,但种子发育不完全,有胚的少,发芽率低,限制了以种子繁殖,不能满足广大人民的要求,为此我组与湖北省林科所协作进行水杉有性生殖过程的研究,借以探明球果结实率低的原因,以供生产者的参考.
Metasequoia was recognized as a tree species extinct before 1943. In 1945, scientists in our country found that the Metasequoia did not disappear after the discovery of the tree species in the red cedar commune and youth commune in Lichuan County, Hubei Province in 1945. Therefore, Living fossils. Since then, the propagation of seeds and cuttings spread at home and abroad, but the seed is not fully developed, with fewer embryos, germination rate is low, limiting the breeding of seeds, can not meet the needs of the general public, for which I group Hubei Forestry Branch collaborative research on the genital Metasequoia reproductive process, in order to explore the reasons for the low coniferous fruit rate for producer’s reference.
