Correlation Analysis of Flower Characters of Prunus mume'Gongfen'
The paper aims to study the overall ornamental features and the interaction degree between flower characters during the flowering period of Prunus mume'Gongfen',and to provide theoretical basis for the scientific management and character evaluation of the flowering period.The flower characters of P.mume'Gongfen'were studied by linear fitting,index variation,R-type clustering,principal component and correlation analysis.In this study,the investigation and correlation analysis of 12 kinds of flowering characters were conducted.The results showed that there was a significant linear correlation between the flower characters,and the best fitting effect was found between petal length and petal width(R2=0.53,Pearson's r=0.73),and the flowering characters had high instability.The number of unblooming,total number of flowers,petal width and pedicel length could be used as reference indexes to judge flower characters.There was a strong correlation among various flower characters,which could regulate flowering characteristics cooperatively.
