Population origin determines the adaptive potential for the advancement of flowering onset in Lupinus angustifolius (Fabaceae)

In this study we used artificial selection to asses the adaptive potential for advancing flowering onset in <em>Lupinus angustifolius</em> L. We establisehd different artificial selection lines in individuals from four populations from two contrasting latitudes in Spain that were sown in a common garden environment. Flowering onset, reproductive success and other plant traits (height, biomass, shoot growth, LDMC and SLA) were measured.

本研究采用人工选择实验方法，评估窄叶羽扇豆（*Lupinus angustifolius* L.）实现开花始期提前的适应性潜力。我们从西班牙两个纬度差异显著的区域的4个种群中选取个体，构建多组人工选择系，并将其栽培于统一的共圃实验环境中。本研究测定了供试材料的开花始期、繁殖成功率以及株高、生物量、地上部生长、叶片干物质含量（Leaf Dry Matter Content, LDMC）和比叶面积（Specific Leaf Area, SLA）等植物性状。
