摘　　要：【目的】探究种源地对红花绿绒蒿果实及种子性状的影响。【方法】测量不同种源地红花绿绒蒿果实大小、种子大小及千粒重,测定不同种源地红花绿绒蒿根际土成分含量,进行果实及种子性状与环境因子的相关性分析。【结果】果实长与土壤pH呈极显著负相关关系(P<0.01),与土壤碱解氮呈显著正相关关系(P<0.05);种子长与经度呈显著负相关关系(P<0.05),与年均降水量呈极显著正相关关系(P<0.01);种子千粒重与经度呈显著负相关关系(P<0.05)。【结论】土壤因子显著影响红花绿绒蒿果实性状,气候因子显著影响红花绿绒蒿种子性状。【Objective】The study is carried out to explore the influence of provenance on fruit and seed characters of Meconopsis punicea.【Method】The fruit size,seed size and 1000-grain weight of Meconopsis punicea from different provenance were measured.The content of rhizosphere soil components of Meconopsis punicea from different provenance was determined,and the correlation between fruit and seed characteristics and environmental factors was analyzed.【Result】The fruit length showed a highly significant negative correlation with soil pH(P<0.01),and a significant positive correlation with soil hydrolyzed nitrogen(P<0.05).There was a significant negative correlation between seed length and longitude(P<0.05),and a highly significant positive correlation with annual rainfall(P<0.01).The seed 1000-grain weight were negatively correlated with longitude(P<0.05).【Conclusion】The soil nutrient in the producing area significantly affects the fruit characters of Meconopsis punicea.The longitude and annual rainfall significantly affects the seed characters of Meconopsis punicea.
