摘要
[目的]研究青刺果几个数量性状的相互关系。[方法]以丽江大具乡白麦村青刺果丰产示范林为试材,通过对青刺果的几个数量性状的相关分析、通径分析和主成分分析,找出了与产量形成有着密切关系并对产量形成起直接重要作用的数量性状。[结果]与产量密切相关的数量性状是冠幅和单花序果数,冠幅主要是通过单株果数来影响单株产量,在生产中要注意协调好冠幅和单花序果数的关系,单果重与单株产量也有正相关关系,在生产中也可适当考虑。[结论]该研究可为今后青刺果的丰产栽培和育种工作提供依据。
[Objective] To study the correlation among some quantitative characters of Prinsepia utilis Royle.[Method] Using Prinsepia utilis Royle produced in Baimai county in Daju Village of Lijiang City as tested materials,correlation analysis,path analysis and principal component analysis of its some quantitative characters were conducted.[Result] The yield of Prinsepia utilis Royle was closely related to crown width and number of single inflorescence fruit,among which crown width affected the yield per plant mainly through fruit number.The weight per fruit had positive relation to the yield per plant.During the production process,it should pay attention to balance the correlation between crown width and number of single inflorescence fruit,as well as weight per fruit and yield per plant.[Conclusion] This study could provide basis for high-yield cultivation and breeding of Prinsepia utilis Royle in the future.
