【摘要】 用来源于河北承德、河南卢氏、甘肃成县和岷县的苦参(Sophora flavescens)种子进行大田试验,研究不同来源苦参的生长发育规律。结果显示,不同来源苦参茎秆、叶数、叶干质量、根生长动态基本一致,叶数和叶干质量均在8月下旬达到高峰,而根干质量在10月下旬达最高。不同来源苦参生长量存在差异,河北承德苦参的株高最低,根干质量最高,叶在前期生长较快,后期衰老也较快,表现早熟特性;甘肃苦参株高最高,茎叶繁茂,后期落叶速率较慢,具有晚熟,产量中等的特性;河南卢氏苦参产量最低。更多还原

【Abstract】 The growth dynamics of Sophora flavescens from different sources which were Chengde City,Hebei Province,Lushi County,Henan Province,Min County and Cheng County,Gansu Province,were studied.The results showed a similar growth dynamics of stem,leaves and root for different source germplasms.The highest number of leaf and leaf dry weight were observed in late August,and for the roots,it appeared in the late October.However,significant differences in terms of biomass among five source germplasms were observed.S.flavescens from Chengde City attained the lowest stem height but the highest root dry weight compared with the others.A relative higher leaf growth rate in the earlier stage and earlier defoliation in the late stage was also observed in Chengde City germplasm,which indicated its early-maturing characteristics.The germplasms from Gansu provience attained the highest plant height with plenty leaves,intermediate production,later defoliation which indicated its late-maturing characteritics.The germplasm from Lushi County,Henan Province attained the lowest production.更多还原
