摘　　要：[目的]探讨何首乌种源的生长、生理、产量和质量等性状的地理变异规律。[方法]以10个何首乌野生种源(GZ、HJ、ZZ、PD、EM、ES、NJ、JZ、TS、SX)为材料,采用完全随机设计研究不同种源何首乌花期、种子成熟期、种子性状、生长节律和生长动态的地理差异。[结果]北端种源何首乌的花期和种子成熟期早于南端种源。各种源间种子长度、种子宽度、种子千粒重、总藤长、总地径及萌条总数均存在极显著差异,GZ的种子宽度和千粒重最大(分别为0.197 cm和0.193 g),种形指数最小(1.387);JZ的种子长度、种子宽度和千粒重最小(分别为0.231、0.131 cm和0.120 g),种形指数最大(1.756)。[结论]不同种源何首乌的花期、种子成熟期及种子性状均存在明显差异。[ Objective] The aim was to study the geographical variation rule of growth, physiological, yield and quality of Polygonum multiflorum Thunb. provenances. [Method] With 10 P. multiflorum wild provenances （GZ, HJ, ZZ, PD, EM, ES, NJ, JZ, TS, SX） as the materials, the geographic variations of their florescence, seed maturity, seed traits, growth rhythm and growth dynamics were studied by completely random design. [ Result] The florescence and seed maturity of north P. multiflorum provenanc.es were earlier than those of south P. muhiflorum provenances. The seed length, seed width, 1 000-seed weight, total fujinaga, total ground diameter and total number of stump plants of different P. multiflorum provenances were all significantly different. The seed width and 1 000-seed weight of GZ were the biggest （being 0. 197 cm and 0. 193 g resp. ） with the smallest seed form index （ 1. 387）, the seed length, seed width and 1 000-seed weight of JZ （being 0. 231, 0. 131 c m and 0. 120 g resp. ） were the smallest with the biggest seed form index （1. 756）. [ Conclusion ] The florescence, seed maturity and seed traits of different P. multiflorum provenances were obviously different.
