长根的

Towards evening the mate and boat-swain begged the master of our ship to let them cut away the foremast, which he was very unwilling to: But the boat-swain protesting to him, that if he did not, the ship would founder, he consented; and when they had cut away the foremast, the main-mast stood so loose, and shook the ship so much, they were obliged to cut her away also, and make a clear deck.

临近傍晚，大副和水手长请求我们的船长让他们砍掉船头第一根桅杆；船长当然是很不愿意干的。但水手长坚持说，如果船长不这样做，船就会被风浪击沉；船长同意了。当他们把这根桅杆砍掉，主桅杆就站立不稳，船也随着剧烈摇晃，他们又只得把主桅杆也砍掉。这样就只剩下一个空荡荡的甲板了。

The 1/2 MS medium supplemented with 1.0 mg·L-1 BA and 0.1 mg·L-1 NAA was very beneficial to the protocorm differentiation and propagation of D.candidum .The highest protocorm propagation index was obtained from the medium containing the activated carbon.The highest root numbers and length were observed in plants growing in 1/2 MS medium containing 0.5 mg·L-1 NAA.

结果与结论：添加20%马铃薯液有利于种胚的萌发，种胚萌发率为79.37%；BA 1.0 mg.L-1和NAA 0.1 mg.L-1最有利于原球茎增殖，培养基中添加2%活性碳原球茎增殖倍数高；NAA有助于试管苗的生根，不同含量NAA以0.5 mg.L-1时试管苗平均根数最多和平均根长最长。

A pot experiment was conducted with two soybean varieties (Di2003-1 and Hefeng25) and two main soil types in Heilongjiang Province to study the interactive effects of variety and soil type on the root morphology and nodule traits of soybean plants. Root samples were collected at the fifth trifoliolate stage, bloom-beginning stage, pod-beginning stage, full pod stage, seed-beginning stage, full seed stage, and full maturity stage for the analysis of root dry mass, root length, root surface area, average root diameter, nodule number, nodule fresh mass, and mass per nodule.

选取黑龙江省2种主要农田土壤类型和2个大豆品种（滴2003-1和合丰25），采用盆栽试验，分别于大豆第5片复叶展开期、初花期、结荚初期、结荚盛期、鼓粒初期、鼓粒期和完熟期取样，进行根系形态（根干质量、根长、根表面积和平均根直径等）和根瘤性状（根瘤数、根瘤鲜质量和单个根瘤质量）的动态分析，以研究品种和土壤类型对大豆根系形态特征的影响。

We measured morphological and physiological characteristics of C. asiatica in spring 2004 and 2005 at three levels: ramet population, clonal fragment and leaf. Environmental factors of different microsites were investigated again in September 2006.
