🔑 Key Concepts & Definitions

• Maïs (Corn): A cereal plant originating from Mexico, requiring warm temperatures and water; classified as a herbaceous, monocotyledonous grass.
• Origine: Native to Mexico, cultivated for its edible grain, and known for its adaptability to warm climates.
• Botanical Structure: A grass with a single stem, bearing separate flowers: the panicle (male flower) and the ear (female flower), with the ear being oval-shaped.
• Reproduction: Involves pollen produced by the panicle, transported by wind to fertilize the ovule in the ear; can be self-fertilization or cross-fertilization.
• Fécondation (Fertilization): The process where pollen fertilizes the ovule, resulting in grain formation; can be auto-fécondation (self) or cross-fécondation (between different plants).
• Maïs Hybride: Genetically crossed maize, obtained by cultivating two different varieties in proximity—one male and one female—to prevent self-fertilization and enhance desired traits.
