Leaf morphology is dynamic, continuously deforming during leaf expansion and among leaves within a shoot. Here, we measured the leaf morphology of more than 200 grapevines (Vitis spp.) over four years and modeled changes in leaf shape along the shoot to determine whether a composite leaf shape comprising all the leaves from a single shoot can better capture the variation and predict species identity compared with individual leaves.

沿芽叶形状的复合建模比单个叶子更好地区分葡萄品种

叶片形态是动态的，在叶片扩张期间和枝条内的叶片之间不断变形。在这里，我们在四年内测量了 200 多种葡萄藤 ( Vitis spp.) 的叶子形态，并模拟了沿着枝条的叶子形状变化，以确定包含单个枝条的所有叶子的复合叶子形状是否可以更好地捕捉变化和与单个叶子相比，预测物种身份。
