Phosphate is a limiting plant nutrient and essential for corn growth and development. Thus, the impact of phosphate fertilization, location, and the variety of modern corn ( L.) hybrids on the profiles of fatty acids, carotenoids, and tocochromanols (vitamin E) was assessed in corn grains. Eight different corn hybrids were grown with (52.9 kg of phosphorus per ha) or without starter fertilizer at three experimental sites in Germany. Location ( < 0.05) and genetics ( < 0.001) but not phosphate fertilization significantly altered the concentrations of individual saturated and unsaturated fatty acids, carotenoids, and tocochromanols. Significant ( < 0.05) interaction effects on the concentrations were mainly observed between the variety and the location. In conclusion, the choice of the corn variety had a more significant impact on the biosynthesis of fatty acids, carotenoids, and tocochromanols than the location or phosphate application on phosphate-sufficient soils.
磷是一种限制植物生长和发育的必需营养素。因此，评估了在德国三个实验地点种植的 8 种不同现代玉米（ Zea mays L.）杂交种在玉米籽粒中脂肪酸、类胡萝卜素和生育三烯酚（维生素 E）的分布特征。在三种实验地点，8 种不同的玉米杂交种在施用（每公顷 52.9 公斤）或不施基肥的条件下进行了种植。地理位置（<0.05）和遗传因素（<0.001）而非磷施肥显著改变了单饱和和不饱和脂肪酸、类胡萝卜素和生育三烯酚的浓度。品种和地理位置之间主要观察到浓度的显著（<0.05）相互作用效应。总之，在磷充足的土壤上，与地理位置或磷施肥相比，玉米品种的选择对脂肪酸、类胡萝卜素和生育三烯酚的生物合成有更显著的影响。
