摘要
杉木穗条不定根的发生属于诱生根原始体型。不定根发生部位有两种类型:皮层生根型和混合生根型,但以皮层生根型为主。不同无性系开始发根时间有显著差异。在观察期内,发根最早的无性系生根时间为23d。
The adventitious roots of cuttings from Cunninghamia lanceolatabelong to the type of root primodia after being induced. There are twotypes of rooting :adventitious roots originated from cortices and adventiti-ous roots originated from calli,with give first places to the former. For-mation of adventitious roots among the clones has a significant differencein date. After cutting, clone NO.119 emerged adventitious roots in 23 days,which is the earliest one among the clones.
