Data and code for "Genetically correlated leaf tensile and morphological traits are driven by<b> </b>growing season length in a widespread perennial grass"

Leaf tensile resistance, a leaf’s ability to withstand pulling forces, is an important determinant of plant ecological strategies. One potential driver of leaf tensile resistance is growing season length. When growing seasons are long, strong leaves—which often require more time and resources to construct than weak leaves—may be more advantageous than when growing seasons are short. Growing season length and other ecological conditions may also impact the morphological traits that underlie leaf tensile resistance. To understand variation in leaf tensile resistance, we measured size-dependent leaf strength and size-independent leaf toughness in diverse genotypes of the widespread perennial grass <i>Panicum virgatum</i> (switchgrass) in a common garden. We then used quantitative genetic approaches to estimate the heritability of leaf tensile resistance and whether there were genetic correlations between leaf tensile resistance and other morphological traits.叶片抗拉伸强度（leaf tensile resistance）指叶片抵御牵拉作用力的能力，是决定植物生态策略的关键因素之一。生长季长度是影响叶片抗拉伸强度的潜在驱动因子之一。当生长季较长时，强壮叶片的构建往往比柔弱叶片需要更多时间与资源，相较于生长季较短的场景，此类强壮叶片此时会更具生存优势。生长季长度及其他生态条件，还可能通过调控叶片抗拉伸强度的内在形态性状，对该特性产生影响。为探究叶片抗拉伸强度的变异规律，我们在同质种植园（common garden）中，对广泛分布的多年生草本植物柳枝稷（*Panicum virgatum*，switchgrass）的多个不同基因型，开展了尺寸依赖性叶片强度与尺寸非依赖性叶片韧性的测定工作。随后，我们采用定量遗传学方法，估算了叶片抗拉伸强度的遗传力，并分析了该特性与其他形态性状之间是否存在遗传相关性。
