番茄（Solanum lycopersicum）是世界上种植最广泛的蔬菜作物之一。传家宝番茄保留了广泛的遗传多样性和相当大的范围内的果实品质和叶片形态性状。传家宝品种在田间条件下生长，并在14周的时间内测量产量锤度（BY）和其他性状。利用偏最小二乘通径模型分析了这些形态和生理性状之间的复杂关系，并建立了一致性模型。光合作用对果实的营养生物量和含糖量有很大贡献，但对产量有负面影响。相反，叶片形状，特别是圆叶，对果实糖含量和产量都有很强的积极影响。如Stupice和Glacier等品种，具有非常圆的叶子，在果实糖和产量方面表现最好。该模型以番茄叶形数据为输入，准确地预测了番茄的BY值，揭示了叶形对番茄果实品质的重要性，圆叶番茄果实品质显著提高。这种相关性保持在一系列不同的遗传背景，并显示了番茄作物改良中叶形态的重要性。
Commercial tomato (Solanum lycopersicum) is one of the most widely grown vegetable crops worldwide. Heirloom tomatoes retain extensive genetic diversity and a considerable range of fruit quality and leaf morphological traits.Here the role of leaf morphology was investigated for its impact on fruit quality. Heirloom cultivars were grown in field conditions, and BRIX by yield (BY) and other traits were measured over a 14‐wk period. The complex relationships among these morphological and physiological traits were evaluated using partial least‐squares path modeling, and a consensus model was developed.Photosynthesis contributed strongly to vegetative biomass and sugar content of fruits but had a negative impact on yield. Conversely leaf shape, specifically rounder leaves, had a strong positive impact on both fruit sugar content and yield. Cultivars such as Stupice and Glacier, with very round leaves, had the highest performance in both fruit sugar and yield. Our model accurately predicted BY for two commercial cultivars using leaf shape data as input.This study revealed the importance of leaf shape to fruit quality in tomato, with rounder leaves having significantly improved fruit quality. This correlation was maintained across a range of diverse genetic backgrounds and shows the importance of leaf morphology in tomato crop improvement.
