Floral traits influence the opportunity for selection among male gametophytes: independent and combined effects of style length and petal area

The data set included here was used for the analyses published in a paper titled, \" American Journal of Botany, for which the abstract is as follows: PREMISE: Strong correlations between traits can obscure their independent effects on components of reproduction. Style length (SL) and petal area (PA) vary within species, for example, but their independent effects on the opportunity for selection among pollen genotypes are poorly understood. Previous work in Clarkia detected a positive effect of SL on pollen receipt, potentially intensifying selection. However, this apparent effect of SL may be influenced by a correlated trait, such as PA. Here, we examine the independent effects of these two traits on pollen receipt and performance.  METHODS: We collected petals and styles from wild populations of two insect-pollinated Clarkia taxa and estimated the independent and combined effects of SL and PA on pollen receipt and performance.  RESULTS: In both taxa, SL and PA are p...本数据集用于发表于《美国植物学杂志（American Journal of Botany）》的一篇论文的分析研究，该论文摘要如下： **前提**：性状间的强相关性可能掩盖其对繁殖组分的独立影响。花柱长度（Style Length, SL）与花瓣面积（Petal Area, PA）在物种内存在变异，但其对花粉基因型间选择机会的独立影响仍未得到充分阐明。此前针对克拉花属（Clarkia）的研究发现，SL对花粉接收量存在正向作用，可能强化选择压力。然而，SL的这一表观效应可能受到相关性状（如PA）的干扰。本研究旨在探究这两种性状对花粉接收量与繁殖表现的独立影响。 **方法**：我们从两个虫媒传粉的克拉花属类群的野生种群中采集花瓣与花柱，并估算了SL与PA对花粉接收量及繁殖表现的独立与联合效应。 **结果**：在两个类群中，SL与PA均为...
