Phenotypic Variations of Fruiting-related Traits of Populations in Paeonia ostii ‘Feng Dan' Native to Qinling Mountains
In order to understand the phenotypic variations of fruiting-related traits of natural Paeonia ostii ‘Feng Dan’ populations native to Qinling Mountains in Shaanxi Province,8 qualitative traits and 14 quantitative traits,concentrating on the leaves and fruits of 8 populations,were systematically observed and analyzed.The results indicated that the variations of plant types existed both within and among populations,while traits,such as branch-growing pattern,color of new branches,leaf shape and fruit color,were significantly different only among populations,but tended to be consistent within populations.As for the quantitative traits,they had great differences except single fruit pod length.Specifically,the average variation coefficients of the quantitative traits of 8 populations were different.Among these traits,the fruit number,the seed number in a single fruit,the length of a single fruit pod had relatively high variations,compared to which the width of a single fruit pod and seed diameter had less variations.Correlation analysis on the relationship betweens environmental factors and the chosen traits suggested that seed number in a single fruit pod of ‘Feng Dan’ was significantly and negatively correlated to latitude,and positively correlated to mean annual temperature.
