玉米果皮保护籽粒发育和灌浆期间种子免受病原菌的危害。果皮也影响水分向种子內外的移动。虽然水能在果皮內自由流动,但基本不是通过它的外表皮吸收水分。果皮的厚度和透性是决定玉米籽粒干燥速率的重要因素。薄果皮品种的干燥比厚果皮品种的快。较厚的果皮也可以较好地抗御籽粒发育期间内部的压力,并防止种子炸裂不使其暴露于病原菌之中。果皮的厚度不大受环境的影响。破碎的果皮与减少发芽、出苗和幼苗活力有关。果皮的柔软性在加工的甜玉米是一个相当重要的品质因素。柔软性,即果皮对受咀嚼而
Corn peel protects seeds from the pathogen during seed development and filling. Peel also affects the movement of water inside and outside the seed. Although water can flow freely within the pericarp, water is not absorbed primarily through its outer skin. The thickness and permeability of the peel is an important factor that determines the drying rate of corn grains. Thin peel varieties dry faster than thick peel varieties. The thicker peel also resists internal pressure during grain development and prevents the seeds from exploding without exposing them to pathogenic bacteria. The thickness of the peel is less affected by the environment. Broken peels are associated with reduced germination, emergence and seedling vigor. The peel’s softness is a very important quality factor in the processing of sweet corn. Softness, that is, the peel is chewed
