摘要
                
                    从20世纪70年代以来江苏省·中国科学院植物研究所开展了落羽杉属(Taxodium Rich.)种间杂交育种研究,并以落羽杉[zdistichum(Linn.)Rich.]为母本、墨西哥落羽杉(T.mucronatum Tenore)为父本培育出‘中山杉302';此后,又以‘中山杉302’为母本、墨西哥落羽杉为父本获得回交一代‘中山杉118',至今已累计扩繁出‘中山杉302’和‘中山杉118’苗木680×104株,造林示范面积达1.9×104hm2。
                
                Effect of mixed-substrate [ V(peat soil): V( perlite):V( sandy loam)= 3:3:1] and sandy loam on rooting and growth of cutting seedlings of Taxodium mucronatum Tenore hybrid clones including ' Zhongshanshan 405',' Zhongshanshan 406' , ' Zhongshanshan 407' and ' Zhongshanshan 502' were studied. The results show that rooting and growth indexes of cutting seedlings of above four clones on mixed-substrate are generally significantly or extremely significantly higher than those on sandy loam, root lignified degree is higher, and rooting position is 1-3 em on basal portion of cuttings. It means that mixed-substrate is suitable for cutting propagation of T. mucronatum hybrid clones.
