The results showed that the sex ratio of trees was 1 m 2 f, and the natural T. cuspidata tree was able to sexually reproduce for many years. Male trees had fecundity when the diameter at breast height ranged from 1.5 cm to 92 cm, while female trees had fecundity when the DBH from 9.5 cm to 68.1 cm. Male trees typically flowered at the age about 20 years earlier than female trees. The numbers of microstrobili were 3 times more than that of megastrobili, and only 1/10 megastrobili developed into seed. The numbers of strobili and seed were correlated with DBH, crown diameter and height of trees; however, no significant correlations were observed with other site factors. Numbers of strobili decreased from the upper to lower canopy layers, while the quantity of seed decreased from the middle, upper to lower canopy layers. Seed-setting rate increased from the upper to lower canopy layers. Numbers of strobili and seeds in different directions of the canopy were not uniform, but the differences weren't significant.

结果表明：现实东北红豆杉天然种群中，♀♂性比为1：2；天然东北红豆杉有性生殖持续时间长，雄株胸径在1.5~92cm，雌株胸径在9.5~68.1cm保持生殖状态，雄株较雌株早约20年进入花期；天然东北红豆杉小孢子叶球数量平均为大孢子叶球数量的3倍，大孢子叶球转化为果实的数量不足1/10，孢子叶球数量、结实数量与样株的胸径、冠幅、树高显著相关，与其他立地因子相关不显著；孢子叶球数量在冠层间的分布呈现由上至下的递减规律，而结实数量在冠层间沿中、上、下递减，结实率沿冠层自上而下递增；孢子叶球与结实数量在树冠不同朝向上也呈现出一定的特点，但总体上差异不显著。

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。

Among them, 7 compounds were firstly found from Trollius chinensis and 4 compounds were firstly found from the genus of Trollius. Most isolated compounds were flavonoid, and few were organic acid. The quality standard studies were conducted by determining the total flavonoids in the flowers of Trollius chinensis at different flowering time and deciding the optimum harvesting time.

在对其质量标准的系统研究中，以总黄酮为指标，对不同花期的金莲花进行了含量测定，确定了最佳采收期；对不同产地10个样品中总黄酮、荭草苷等活性成分进行了含量比较，结果表明金莲花中黄酮类成分含量稳定，适于在制定质量标准时作为含量测定的指标成分；通过对不同产地10个样品指纹图谱的比较，确定了21个共有峰所代表的化合物为金莲花的药效物质基础。
