中文摘要：

目的研究汉城细辛种群构件结构及其生长规律,包括分析汉城细辛生物量、根数量及龄级的生长规律。方法采用大样本随机取样的调查和测定方法。结果汉城细辛生物量和根数量之间有着密切的同速生长关系,且相关系数R值较高;汉城细辛龄级与根数量、龄级与生物量之间均具有异速生长关系。结论说明汉城细辛生物量的增加很大程度取决于根数量的增加;随着龄级的增加汉城细辛生物量、根数量也随着增加,但相对生长率不相等。

英文摘要：

OBJECTIVE To analyze the structure and growth pattern of the biomass,root number,and age class of Asarum sieboldii f. seoulense. METHODS A large sample,random sampling investigation and determination method were used. RESULTS The biomass and root number of Asarum sieboldii f. seoulense were correlated with the growth speed; the correlation coefficient was high. There existed allometric relationship between the age class and the number of roots of Asarum sieboldii f. seoulense; the age class and biomass had allometric relationship. CONCLUSION The increase of the biomass of Asarum sieboldii f. seoulense depends on the root number; with the increase of the age class,the biomass and root number of Asarum sieboldii f. seoulense increase,but the relative growth speeds are not equal.
