Analysis of fruit and seed characters of Meconopsis punicea from different provenance
[Objective]The study is carried out to explore the influence of provenance on fruit and seed charac-ters 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 differ-ent 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 corre-lation 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.
